IDEXX EquiView® Digital Radiography System Operator’s Guide 1Getting StartedOverviewThe IDEXX EquiView® Digital Radiography System is a high-resolution digital X-ray system that generates X-ray images without films and chemistry. The digital X-ray plate is exposed by a diagnostic X-ray apparatus and the X rays are then directly converted into electrical signals. These signals are read by the X-ray generator and then converted into images by the EquiView software and displayed on the monitor. The images created by the EquiView software allow you to view both bone and soft tissue structures in one image with one single exposure. You can easily view and enhance relevant areas and structures for diagnosis. In addition, areas of an image can be enlarged up to three times without significant pixelization. Because of the high quality of the monitor, the IDEXX EquiView Digital Radiography System is suitable for mobile application as a digital X-ray computer as well as for diagnostic purposes.ComponentsThe basic components for the IDEXX EquiView Digital Radiography System consist of a computer, a digital X-ray plate, two switch boxes, a trigger, and a remote control. These components form a compact system for taking, processing, and archiving digital X-ray images. ComputerThe portable, Microsoft® Windows®-compatible computer runs the EquiView software, which lets you view, manage, and archive the image files created from the digital X-ray plate.Digital X-ray PlateThe digital X-ray plate is an ultracompact, portable plate for use in place of a regular film cassette, and can be used with any X-ray source generally available (portable sources should have a high-frequency, full-wave rectification (e.g., Gierth 80 HF ultralight). The plate generates digital X-ray images without using X-ray film or foil. The X rays are converted directly into an image and displayed on the computer. The direct conversion of the X rays into electrical signals without the use of a scintillator absorbs less energy, thereby reducing blurring. As a result, the various structures are better differentiated so that images are sharper and provide greater detail. The plate’s active imaging surface is 20 x 25 cm (8 in x 10 in). Switch BoxesThe switch box is the interface between your X-ray generator and the IDEXX EquiView Digital Radiography System computer. There are two switch boxes—one for the manual trigger setup and one for the remote control setup. Be sure you are using the correct switch box for your desired setup.Computer and monitorCarrying handleCableActive imaging surfaceDigital X-ray plate Manual trigger switch box Remote control switch box

IDEXX EquiView® Digital Radiography System Operator’s Guide 3Setting Up the IDEXX EquiView® Digital Radiography SystemEnsure that all components are present. Keep the packing materials in a dry place in case you need them later.CAUTION: The room temperature must not drop below 5°C (40°F) and must not rise above 35°C (95°F). There is a risk that the active layer of the digital X-ray plate can be destroyed.CAUTION: When the EquiView Digital Radiography System is taken out of a cold environment and put into a warm room, condensation may form. In this case, the equipment must not be connected to an electrical source because there is a risk of damage. Wait until the EquiView Digital Radiography System has warmed up to the ambient temperature and condensation has completely dried. This may take several hours.The initial installation may only be carried out by suitably qualified personnel. Initial InstallationYou can configure your EquiView Digital Radiography System to use a manual trigger or a remote control to take X rays. Decide which configuration you prefer before beginning the initial installation.Computer connections for the manual triggerConnect the digital X-ray plate data cable here Connect the trigger cable hereConnect the power cord hereDigital X-ray plateto computer video cardData cableSwitch box for manual triggerComponent connections for the manual triggerto computerto X-ray generatorX-ray cableTriggerTrigger cable
4 IDEXX EquiView® Digital Radiography System Operator’s GuideConnecting the Components1. Connect the digital X-ray plate to the computer’s video card with the data cable provided. NOTE: Use only the data cable provided with the EquiView Digital Radiography System.2. Connect your X-ray generator to the switch box’s “X-ray gen” socket with the X-ray cable. NOTE: There are two switch boxes—one for the manual trigger configuration and one for the remote control configuration. Be sure you are using the correct switch box for your desired configuration.3. Connect the trigger to the switch box’s “Hand s/w” socket.4. For the manual trigger configuration, use the trigger cable to connect the switch box’s “detector” socket to the computer.5. Turn the switch box to the “on” position. 6. Connect the power cord to the computer and then to an appropriate electrical source, and turn on the computer. TIP: When using extension cords for your X-ray generator, make sure you use heavy duty, large-core diameter cords because this will reduce the losses that long power cords incur. These losses significantly affect the output of X-ray generators. Ideally, always use the shortest cord possible for the X-ray generator.Component connections for the remote controlSwitch box for remote controlDigital X-ray plateto computer video cardTriggerto X-ray generatorX-ray cableData cableComputer connections for the remote controlConnect the digital X-ray plate data cable here Connect the power cord here

8 IDEXX EquiView® Digital Radiography System Operator’s Guide Click the plus (+) sign to expand the exams and display the sub-exams and specific views. Click the individual images needed, or click the box next to the main exam heading to choose all items within that heading. NOTE: In addition to taking these images, you can choose to either cancel the selection and start over again, or select another horse.4. Click the Take Images button at the bottom of the screen to open the Take Images screen and begin to take X rays.Taking X raysThe EquiView Digital Radiography System has a very large dynamic range, which means that careful technique setting is no longer a necessity, with certain exceptions. The most likely error that can occur is underexposure, in which only a part of the dynamic range of the digital X-ray plate is used. In this case, especially bony structures appear significantly less structured and there is a risk of losing important information about these areas.Special X-ray Views• Thick body parts: AP Stifle, Neck, and Spinous Processes. These thick body parts are at the limit of penetration for the small handheld generators. However, the EquiView Digital Radiography System is still able to produce good quality images provided some important points are kept in mind. Thick body parts produce a large amount of scatter, which tends to fog the image. Due to the high dynamic range of the EquiView Digital Radiography System, the image is very sensitive to scatter. This means in practice that there is a limit on thick body parts where increasing mAs Set Up Exam screenChoose Exam Types screen
IDEXX EquiView® Digital Radiography System Operator’s Guide 9becomes limiting and does not improve image quality after a certain level. TIP: Moving the X-ray source closer to the body part, which increases the effective kVp, may have a better impact on the image than simply continuing to increase mAs.• Equine foot: The equine foot is another body part that produces a great deal of scatter. To produce good images of the navicular bone, similar techniques to the above may be helpful. A grid is always helpful for images where a grid can be easily used, in respect of maintaining the geometric requirements. In addition, lead shielding of unwanted parts of the image can be helpful.To expose the plate:1. Place the digital X-ray plate into your X-ray equipment’s holder for film cassettes or in another suitable position. The plate’s active imaging surface must face the radiation source. 2. Select suitable settings on your X-ray equipment for exposure time and accelerating voltage. WARNING: National regulations for dealing with X-ray radiation and the operation of X-ray devices applies. Do not exceed the applicable national standards for the radiation doses. Pay particular attention to the safety of the personnel in the vicinity of the X-ray equipment. TIP: Use high kV and low exposure time. Dose increases proportionally with the kV, but to second order with time. TIP: Using old generators that do not have full-wave rectification and have exposure times over 0.2 seconds is not ideal. If you have been using a good quality X-ray generator in the past, setting kVp at 80 and mAs at 1.8 is ideal for most exams. TIP: Most X-ray generators have a milliamperage of 15 mA, so the time factor would be set to 0.12 seconds: 15 mA x 0.12 s = 1.8 mAs. For large structures, 80 kVp and an mAs-product of 15 mA x 0.25 s = 3.75 mAs can be used. 3. Ensure that the desired structures are located between the X-ray source and the digital X-ray plate. The plate must be aligned vertically to the direction of incidence of the X-ray beams. The film-focal distance (FFD) should be in the range of 55–60 cm (21.6"–23.6"). TIP: The X-ray generator should be placed closely to the region of interest. TIP: Movement artifact is usually a combination of movement of the X-ray source, the horse and the plate itself.4. Press and hold the exposure switch halfway down until you hear the beep indicating that the plate is ready for an exposure. This prepares the generator and plate, and can take up to 4 seconds. In addition to the beep, the light on the plate turns from green to red, and a blue progress bar appears at the bottom of the computer screen and moves halfway across.Take Images screen (X-ray mode)Image area Borderline
10 IDEXX EquiView® Digital Radiography System Operator’s Guide5. After any of these signals, fully press the switch to take the image. The computer beeps, the blue progress bar continues across the computer screen, and the light on the plate changes from red to green.6. The processed image appears on the monitor within 12–15 seconds. The next image can be taken after 5–8 seconds, when the 20-second cycle time of the plate has elapsed. Skipping an ImageThe EquiView software looks for the first unchecked check box in the Examination section and associates the image to be taken with that view. You can skip image views (if necessary or desired) by selecting the check box next to that particular image.Reshooting an ImageTo reshoot an image, click the view name (it turns blue), then right-click and select Reshoot Image. This deletes the original image, and the software prompts you to confirm the deletion.NOTE: If you have opted to reshoot an image and then decided to skip it until later, the image view name will remain highlighted in gray and the Done button will be disabled until that view is reshot.Taking Additional ImagesTo take multiple images of the same view, deselect the check box in front of the image name after the Take Image screenBetter picture of a stifle due to reduced distance between the X-ray generator and the region of interest

NOTE: To exit this screen, click the blue Back button; the View Images screen appears.Review Images screen (9 images at one time)
14 IDEXX EquiView® Digital Radiography System Operator’s GuideManipulating ImagesThe IDEXX EquiView® software allows for certain settings to be adjusted to change the appearance of the “first view.” The first view is the image that appears on-screen after these automatic settings are applied. You can then manually change window and level settings and apply other functions, such as edge enhancement when looking for a stress fracture. During installation, your IDEXX representative will adjust the appearance of the first view to suit your preference and the performance of your X-ray generator.After the image is taken, you have a full range of tools to use to manipulate the image. Images already taken are automatically stored and sequentially numbered in accordance with the presettings made by you. You can take all relevant images, and then optimize the settings for the images and make the diagnosis.Dynamic Views The mathematical treatment of the raw data from the plate is a very complex combination of functions known as an algorithm. IDEXX has developed an algorithm that shows some soft-tissue features while still allowing you to view dense bone detail. This is one of the features that makes the EquiView Digital Radiography System unique. Window and Level AdjustmentsThe Window function is a representation of the amount of image data viewed at one time (contrast). The Level function is a measure of the relative luminance of the pixels within the window (brightness). The Window and Level functions adjust the contrast and brightness as a secondary function to the primary purpose of making various structures in an image visible on the screen. Window and Level both have a numeric value that is displayed in the middle of the right border of the active viewing window.The same picture using different parameters in the software to show the bone structuresX ray of a hock showing clear soft tissue structures
IDEXX EquiView® Digital Radiography System Operator’s Guide 15If you “window” and “level” a typical image, you can view individual hairs on a limb while still being able to “window” back to dense subchondral bone detail. With film, this is generally very difficult, and it is standard practice to take two different exposures to identify subchondral bone features of the distal condyles of MCIII and a second lower-energy setting to identify any possible osteophyte or enthesiophyte formation around the joint. The dynamic range of the digital X-ray plate and the EquiView software allow all these details to be seen in one image.To adjust the Window, click and drag the cursor:• Left to right to increase the Window • Right to left to decrease the WindowTo adjust the Level, click and drag the cursor:• Bottom to top to increase the Level • Top to bottom to decrease the Level Window and Level default valuesWindow adjustment—increased for high contrast Level adjustment—increased for brightnessX ray of a hockTIP: Drag the cursor diagonally to adjust the Window and the Level simultaneously.
16 IDEXX EquiView® Digital Radiography System Operator’s GuideLevel and Strength AdjustmentsYou can apply different algorithms to the image by adjusting the numbers in the Image Manipulation dialog box.Level—Adjusting the Level between and 1 and 4 flattens or deepens the image.Strength—Adjusting the Strength between 0 and 100 softens or sharpens the image.Zoom, Rotate and Move Adjustments Zoom—To zoom in on an image, press and hold the Z key on the keyboard and then scroll with the mouse. Or, right-click and scroll up.Rotate—To rotate an image counterclockwise, press and hold the A key on the keyboard.

24 IDEXX EquiView® Digital Radiography System Operator’s GuideTransportation and StorageThe active imaging surface of the digital X-ray plate is sensitive to temperature. To ensure safe transportation and storage of the digital X-ray plate, always transport and store the plate in the supplied case. Connect the digital X-ray plate to a power supply (Connector 1) or to the 12-volt electrical system (Connector 2) of your vehicle as shown in the diagram, and turn on the temperature control. This ensures that the plate is always transported and stored in the optimum temperature range. CAUTION: At temperatures below 5°C (40°F) or above 35°C (95°F), changes to the surface can occur. At temperatures above 40°C (104°F), depending on time and temperature, irreversible changes will take place.If the ambient temperature rises above 27°C (80°F) or falls below 10°C (50°F), make sure the case is connected to a main power supply or to the 12-volt electrical system of your vehicle and is turned on. The plate can be used in the extreme temperatures as long as it is placed into the case between taking shots.A combined heating and cooling element (Peltier element) is installed in the transport case, and insulation ensures that the temperature within the case changes very slowly. The red LED indicates temperatures below 15°C (60°F) and the temperature control module has automatically turned on the heating. The green LED indicates temperatures above 35°C (95°F) and the cooling is active. If the temperature range is above 15°C (60°F) or below 35°C (95°F), none of the LEDs light up; the temperature in the case is within the allowable temperature range and is displayed on the temperature control module. When heating or cooling is active, the temperature control module will keep heating or cooling until a temperature of 25°C (77°F) is reached in the case.IMPORTANT: Transport and store the digital X-ray plate only at temperatures of 5°–35°C (40°–95°F). Transportation, operation, and storage at temperatures exceeding this temperature range may permanently damage the digital X-ray plate. Damage to the plate due to inappropriate temperatures is not covered by warranty.digital x-ray plate Transport case with temperature controlOn/Off switchIndicator LED “Heating”Indicator LED “Cooling”Connector 1, 110-230V ACConnector 2, 12V DC
IDEXX EquiView® Digital Radiography System Operator’s Guide 25Optional AccessoriesTransport case and X-ray plateOnly the supplied case with built-in temperature control may be used for transporting and storing the digital X-ray plate. The Peltier element built into the case maintains the temperature inside the case reliably below 35°C, even in the event of external temperatures around 45°C. The case containing the digital X-ray plate must not be exposed to direct sunlight or kept inside a vehicle in direct sunlight. The case must be supplied with power using only the cable provided. The case can be connected to a main power supply (110V–230V on socket 1) or to a 12-volt vehicle electrical system (socket 2).NOTE: After connecting the power supply, it is absolutely necessary that the temperature control of the case be switched on using the switch and the case closed. This ensures that the valuable plate has a long service life.UPS (Uninterruptible Power Supply)The UPS ensures smooth operation of the EquiView Digital Radiography System even if the power supply fails.
