1 © Varian Medical Systems | X-Ray Products 10 Intended Use The PaxScan 4336Wv4 receptor is a light weight, wireless flat panel detector designed for medical and veterinary use. The 4336Wv4 fits standard bucky trays and its wireless communication enables easy migration between table, above the table, chest stand, and mobile cart applications. This family model will acquire image over a wide range of dosage, while providing maximum access to the patient, with a minimum possible border on the active imaging area. An additional cable is supplied with the receptor to allow for set-up of the wireless interface and retrieve images from the receptor in the case of failed wireless transmission. Figure 1-0 Patient Contact Surfaces – 4336Wv4
Chapter 2 © Varian Medical Systems | X-Ray Products 11Getting Started System Overview In medical applications, the function of the 4336Wv4 FPD is to absorb the X-rays that pass through the patient’s anatomy and convert them into a digital image. The wireless access point is the interface between the FPD and the imaging system and may be mounted in an equipment enclosure, or it may also be wall or ceiling mounted to maximize wireless signal strength. The Receptor is provided with a software application package, Virtual Command Processor (VSP), which performs all the interface functions with the receptor; such as, communication and respective calibration. During operation, the Receptor is often draped or bagged to ensure cleanliness and sterilization, and is manipulated such that the Receptor’s input window is located near, but on the opposite side of the patient, from the X-ray source. Figure 2-0 shows the configuration of the Receptor in the context of the overall imaging system. The dimensions for receptor are 459.5mm x 383.5 x 15.13mm. Figure 2-0 Imager Configuration

Chapter 3 © Varian Medical Systems | X-Ray Products 17PaxScan System Software The PaxScan 4336Wv4 receptor is part of a new series of Flat Panel Detectors which deploy the Varian Smart Panel (VSP) architecture. Imager software is composed of two parts: 1. Software necessary to capture, process, and correct x-ray images is embedded within the receptor; 2. The VSP COMM workstation libraries comprise the VSP SDK. Because the main software is embedded within the receptor, the only software required on the workstation is a small set of DLLs that should be copied from the DVD to the workstation. The VSP COMM libraries are copied to the workstation. Software interfacing to this receptor will make API calls to these SDK libraries to control the image acquisition process. These libraries manage connections to the receptor and the transfer of files from the receptor to the workstation. The contents of the DVD include the following files: 1. VSP COMM (SDK) files: a. libvsp.dll b. libvsp-zf.dll c. libwinpthread.dll d. vspcs.dll e. vsp.h This set of files should be copied to the workstation. For customers working with C/C++, a vsp.h header file is included along with the libraries. For customer working with C#, the vspcs.dll provides the C# wrapper interface. 2. FP2032_VarianSmartPanel_SoftwareInterfaceSpecification.pdf – This .pdf file provides API documentation for the software. 3. Bonjour installation files a. Bonjour.msi b. Bonjour64.msi Bonjour is an optional installation and is required if you use the List()/vsp_list() API function. 4. Sample Code a. vsp-example.cs – C# sample code project b. vsp-example.c– C/C++sample code project 5. Utility software a. vsp-example.exe The vsp-file.exe utility is used to transfer a configuration file to the receptor.

Chapter 4 © Varian Medical Systems | X-Ray Products 18 Modes of Operation The PaxScan 4336Wv4 supports the radiography mode of operation as defined in Table 2-0. In general, there is a tradeoff between varying operation modes of resolution, or field of view, or cycle time, or noise. The sensitivity of the imager is optimized to match the X-ray dose used in each mode. The purpose of each mode is to configure the detector to achieve optimal performance during specific imaging procedures. Modes are defined by a combination of factors, such as cycle time and analog gain. Each mode requires a unique set of calibration files. Note: The system may be in only one mode at a given moment. Not every mode will be available with every system. The OEM should work with PaxScan technical support for configuration of the mode(s) which best suit the customers intended application Table 1-0 PaxScan 4336Wv4 Operational Modes Mode Cycle Time Pixel Binning Panel Scan Time X-Ray Window Time Image Area Frame Size Acquisition Type Radiography – Full Resolution 7 sec 1 x 1 550ms 0.35 to 3.5s Full Field 2,476 x 3,072 Accumulation
4 © Varian Medical Systems | X-Ray Products 19Default Mode Mode 0 is the default. The default mode will be invoked automatically upon system power-up when a link is opened or receipt of a reset state command. Operation States The operational states of the imager can be categorized as follows: x Radiography acquisition: (Radiography-type) x Offset Calibration: (OEM-initiated) x Gain calibration: (always-OEM initiated) x Analog offset calibration: (always OEM-initiated) Each operating mode employs all types of calibration. In radiography-type acquisitions, the PaxScan 4336Wv4 will acquire one frame with its respective offset.
Chapter 5 © Varian Medical Systems | X-Ray Products 20 Calibration Procedures Offset Calibration Offset calibration compensates for fixed pattern pixel intensity variations in the image associated with the dark current and electronic offsets. The Offset reference image is an average of a series of frames acquired without X-ray illumination and referred to as dark fields. f x Offset calibration should not be performed during X-ray. x The X-ray-to-digital conversion factor does not change as a result of calibration. Preview Offset Calibration There are two types of offset calibration; one is used for the preview image and the other to calibrate the final image. Prior to acquiring images, an offset calibration must be performed in each mode. This offset calibration is used for the preview image. In addition, an offset calibration is automatically performed after each single acquisition. Step Action / Results 1. To perform offset calibration, click the ViVA icon launches the application 2. Ensure required receptor appears in the Mode drop down. The 4336WV4 currently supports Rad 1x1 3pf. Click Offset Calib. Button or select from the menu bar under Acquisition.
5 © Varian Medical Systems | X-Ray Products 21Step Action / Results 3. A Calibration Setting window appears followed by an offset Calibration Progress window. 4 The number of frames acquired can be selected from the Settings window. Once all frames are acquired, the receptor is updated with the averaged offset calibration frame for the current mode. The updated message will show on the progress window and calibration process is complete. Press Close button to close the window.
5 © Varian Medical Systems | X-Ray Products 22 Gain Calibration To compensate for non-uniformities in the Receptor, a gain reference image (flat field) is used by the Corrections module as required to correct all images. The flat field image must be captured by the Varian Smart Panel (VSP) prior to acquiring images. The process of capturing the flat field image is known as Gain Calibration. Note: Every time a gain calibration process is run, an offset calibration is enforced beforehand. This will ensure that the receptor is properly calibrated. Gain calibration is based upon the linear response of the Receptor to dose. Normalization is achieved by applying the flat field image acquired during the Gain calibration to all images corrected by the VSP. Normalization will fail with pixels that are responding to dose in a non-linear manner. Pixels responding to dose in a non-linear manner are usually caused by the saturation of the Receptor, or a low signal-to-noise ratio. Note: It is critical to acquire the flat field image within a range that is large enough to be higher than the background noise created by the X-ray source and readout electronics of the Receptor, but lower than the saturation point of the imager. Flat field images acquired near or exceeding the saturation point will cause normalization failures with all images acquired until a Gain calibration with the correct dose is performed. We recommend that flat field images be acquired with a median count of approximately 13000 - 14000. This range will ensure that Gain calibration will meet both the upper and lower dose requirements under all modes of operation. Dose requirements are determined by the settings of the generator X-ray source. To reduce the effects of noise, the average of each pixel in the flat field image is calculated by accumulating a number of frames into an internal memory buffer, then dividing the sum of each pixel by the number of frames acquired. Note: Using larger numbers of calibration frames to capture the flat field image will result in more accurate calibration. Important: Gain calibration requires the production of X-rays and therefore certain precautions must be taken by the human operator. The number of calibration frames used during Gain and Offset calibrations can be adjusted under the Mode Settings pull down menu. We recommend accumulating 32 frames for gain calibration and 8 frames for offset calibration for optimal image quality. However, the actual number of calibration frames used must be determined solely by the system integrator depending upon their specific performance requirements.
5 © Varian Medical Systems | X-Ray Products 23The general procedure for Gain calibration for all modes is as follows in Table 2-0 and described in the next section. Detailed instructions on performing gain calibrations are covered in the ViVA Online help documentation. Table 2-0 Gain Calibration: All Modes Step Action Results 1. Warm Up To ensure proper warm up, the PaxScan 4336Wv4 Receptor must be operational for a least 30 minutes prior to Gain calibration. 2. Offset Calibration Software performs a new Offset calibration referred to as dark field acquisition. Note: X-Rays must not be used for this part of the calibration. 3. X-Ray Radiation A uniform flat field with no obstructions in the path of the X-Ray beam. The radiation should ideally be at a level and technique representative of the typical radiation dose for the Receptor during typical procedures, keeping in mind the general consideration outlined above. 4. Repeat The above procedure must be repeated for each of the stored imaging modes.
5 © Varian Medical Systems | X-Ray Products 24 Radiographic Mode Gain Calibration Radiography Gain calibration requires an Offset calibration performed prior to collecting the Flat Field image. Therefore an Offset Calibration process must be run prior to the gain Calibration. X-Ray illuminated frames are then offset-corrected and accumulated in the VSP. A series of accumulated frames equals one radiographic X-ray exposure. Exposures are averaged to obtain the Flat Field image used by the VSP. The number of exposures acquired can be selected from the Settings window. Important: VivA provides a convenience of running Offset Calibration as part of the Gain Calibration process. However, API driven Gain Calibrations do not automatically run Offset Calibration. OEM Applications should be sure to run Offset Calibration prior to Gain Calibration. Take the following steps to complete radiographic gain calibration. f Step Action / Results 1. Ensure the desired receptor and imaging mode appears in the Mode drop down. 2. Click Gain Calibration from the menu bar under Acquisition invokes hardware handshaking for the dark field calibration. 3. Finish Offset Calibration process as explained earlier
5 © Varian Medical Systems | X-Ray Products 25Step Action / Results 4. Use operator control to perform an exposure. Once all x-ray frames have been acquired click Finish to Complete the calibration. The number of frames acquired can be selected from the Setting window. Once all X-ray frames have been acquired, the receptor is updated with the averaged gain calibration from for the current mode. The updated message will show on the progress window and calibration process is complete. Press Close button to close the window. Note: Operator Control is user supplied equipment. Note: Gain calibration should be performed at regular intervals, typically once every six (6) months, or whenever the central beam of the X-ray source has been moved relative to the Receptor. Replacement of the X-ray tube will require a new gain calibration to be performed. Note: Varian recommends accumulating 32 frames for gain calibration for optimal image quality. However, the actual number of calibration frames used must be determined solely by the system integrator depending upon their specific performance requirements. Note: For additional assistance operating ViVA™, use the ViVA Online help documentation.
