QuickGuide

2D Opt

This opmizaon emphasizes the higher, lower, or mid-range

frequencies while imaging the enre bandwidth.

Note

Not all opons are available in every TSP.

In harmonic imaging, the leer H appears before the 2D Opt

selecon on the monitor and touchscreen:

• HRES

• HGEN

• HPEN

XRES

Up to 5 Variable XRES sengs are available on select

transducers and TSPs, 1=course, 5=smooth.

To acvate Variable XRES, press the associated rotary knob, and

then turn the rotary knob to the preferred seng.

XRES image processing reduces speckle noise arfacts and

improves image clarity and margin denion. Transducers and

TSPs with Variable XRES enabled have sengs that provide

smoother images as XRES level is increased.

Tip

Make user-dened TSPs that are customized for the customer.

The current variable XRES seng appears to the right of the

image if Variable XRES is available.

SonoCT

Real-me mulple lines-of-sight imaging increases ssue

informaon and improves display of curved and irregular

structures while reducing many angle-generated arfacts.

SonoCT provides:

• Increased margin denion

• Reduced angle-generated arfacts

• Virtual eliminaon of speckle noise

• Improved delineaon of curved structures

WideScan

1Press SonoCT.

Press WideScan.

• Provides a quanable image of structures larger than the

tradional eld of view.

• Demonstrates anatomic spaal relaonships.

• Allows for bi-direconal construcon of the panoramic

mosaic.

The muliple lines-of-sight acquired with SonoCT are clearly

demonstrated with a paper clip against the transducer lens cap.

Available on linear and curved arrays while in SonoCT mode.

Similar in appearance to trapezoidal imaging but not the same.

AutoSCAN

• Only available in 2D mode.

• Gain and TGC can also be manually adjusted when

AutoSCAN is on.

Press iSCAN to automacally adjust TGC, receiver gain,

compression maps, spectral Doppler PRF, and baseline during

real-me scanning.

AutoSCAN automacally and connuously opmizes 2D image

brightness at the default gain and TGC sengs.

iSCAN

• Evaluates grayscale distribuon to opmize TGC and 2D gain.

• The iSCAN icon appears in the boom le-hand corner of

the monitor when acvated. The iSCAN icon turns red for

three seconds to indicate the image has been opmized.

Tip

In 2D iSCAN opmizes system sengs based on the frame

acquired at the moment iSCAN is pressed. These sengs

remain unchanged unl pressing iSCAN again, touching Reset

iSCAN, or changing the associated controls manually.

Note

There is no visual indicator that AutoSCAN is on.

Tissue Harmonics

Tissue Harmonic imaging provides enhanced image contrast

resoluon and images with fewer arfacts, parcularly in cysc

structures.

• Reduces image arfacts and increases resoluon; the trade-

o is less penetraon.

• Does not impact frame rate.

• More clarity in acousc enhancement and shadowing.

Tip

Useful in dicult-to-image paents.

This user-selected speed of sound compensaon maintains

exceponal sharpness on fay and dense breast ssue.

Tissue Aberraon Correcon (TAC)

• Uses speed of sound correcon, applied to both transmit

and receive signals, throughout adipose ssue.

• SonoCT frames will be beer registered at the lower speed

of sound.

• Advanced XRES will not be eected by changing TAC because

Advanced XRES is a post-processing funcon.

• Reduces the eects of acousc beam distoron.

• Sharpens spaal resoluon.

• Improves ssue uniformity throughout the depth of view in

TDP.

Notes

• The C5-1 penetraon TSPs use TAC in the rst 3 cm of ssue.

The Advanced Breast TSP uses TAC throughout the image.

• Tissue with higher fat content causes in speed of sound

changes and reducon of overall image sharpness and

decreased ssue denion.

In Harmonic mode, the indicator appears to the upper right of

the image.

Gray Map

The Gray Map feature controls the levels of grays and whites in

the image.

• Gray Map selecons range from 1—5.

• This feature controls transions from “more whites” to

“aer whites.”

Note

This is also a post-processing feature.

Dynamic Range

Press the rotary knob on the system control panel to switch

between Dynamic Range and DRS modes. When acvated, Dyn

Range is highlighted on the touchscreen.

Dynamic Range is the default opmizaon seng for imaging in

2D Opt, allowing for adjustments, adjusng up for more shades

of gray and down for fewer shades of gray.

Access Gray Map on the third page of the 2D touchscreen. To

change the Gray Map level, turn the rst rotary knob.

The Gray Map level also appears at the top of the grayscale bar

on the monitor screen.

• DRS is a macro control that adjusts mulple parameters

simultaneously to opmize funcons such as:

– Line density

– Persistence

– Number of lines of sight (SonoCT)

• R1 is opmized for maximum image quality.

• RS provides the best overall choice of system sengs.

• S1 is opmized to improve speed.

Dynamic Resoluon System (DRS)

Note

Some system sengs, such as Persistence and SonoCT steering

angles, aect temporal response but not frame rate, therefore

frame rate (FR) annotaon may not change when adjusng DRS

to speed.

DRS provides one-buon temporal vs. spaal resoluon in 2D

and 3D modes.
