Changing Patient Information or an Exam (continued)
4.  To have the database shown in its entirety, Backspace on 
the Search string and all patient names appear.
5.  Press Register to register the new exam.
A new exam is automatically created on that patient unless 
an exam already exists on that day for that patient.
If an exam already exists for that patient, the following 
warning is displayed.
 Figure 4-5. Dialog Box
Select “Yes“ to reuse the existing data.
Select “No” to create a new exam for the patient.
6.  To display the patient information on the title bar, press 
Scan on the Touch Panel, the Esc key or the B-Mode key. 
Select the Preset and appropriate probe Touch Panel keys, 
if necessary.

Selecting an Exam Calcs
The exam category preset that best describes the desired exam 
to be performed is chosen after the exam category is selected. 
The factory default preset selections are displayed on the Touch 
Panel.
A typical example for the Abdomen exam category is shown 
below.

Selecting a probe
Select the appropriate probe from probe indicator. Some probes 
are used in more than one exam category. The system has pre-
programmed applications for probe use. 
•  Always start out with a probe that provides optimum focal 
depths and penetration for the patient size and exam.
•  Begin the scan session using the default Power Output 
setting for the probe and exam.

Chapter 5
Optimizing the Image
Describes how to adjust the image. This chapter is 
broken into the following sections: B-Mode, M-Mode, 
Color Flow Mode, Doppler Mode, and 3D Mode.

Optimizing B-Mode
Intended Uses
B-Mode is intended to provide two-dimensional images and 
measurement capabilities concerning the anatomical structure 
of soft tissue.

Typical B-Mode Exam Protocol
A typical examination using B-Mode might proceed 
Table 5-1: Typical B-Mode Exam
StepInstructions
1.  Record exam-related patient information. Verify system 
setup (probes and presets). 
2.  Position the patient and the console for optimum 
operator and patient comfort. Perform the scan. 
Add important data to the image: annotations and 
measurements. 
Record results: print hard copies, CINE review/optimize 
image capture, and VCR recording. 
3.  Complete the study by collecting all the data.

B-Mode Scanning Hints
HINTSThese B-Mode controls produce the following results: 
Auto Optimize. Improves imaging performance while reducing 
optimization time. Available in B-Mode and Doppler Mode. 
Frequency. Changes system parameters to best optimize for a 
particular patient type. 
Dynamic Range. Affects the amount of gray scale information 
displayed. If you increase the gain, you may want to decrease 
the Dynamic Range. 
Edge Enhance. Affects the amount of border crispness. 
Frame Average. Smooths the image by averaging frames. 
Affects the amount of speckle reduction. 
B Softener. Affects the amount of lateral smoothing. 
TGC. Adjust TGC and keep Gain at a lower setting. 
Focus Number/Position. The best focusing is at the focal 
zone location. Put focal zone(s) at the area of interest. Be 
conscious of where the focal zones are. Focal zones must be 
moved to track at the center of the anatomy of interest. If there 
is flicker, decrease the resolution and increase the frame 
averaging. As a last resort, decrease the number of focal 
zones. 
Scan Area. Sizes region of interest. Adjust the Scan Area to 
the smallest reasonable size to maximize frame rate.

Depth
DescriptionDepth controls the distance over which the B-Mode images 
anatomy. To visualize deeper structures, increase the depth. If 
there is a large part of the display which is unused at the bottom, 
decrease the depth. 
AdjustingEach adjustment cycles you to the next Depth setting. Imaging 
and display parameters adjust automatically. 
To increase/decrease, adjust Depth. 
Va l u e sDepth increments vary by probe and application. Depth displays 
on the monitor in centimeters. 
Depth values are returned to the factory or user preset value 
when you change the following: Probe, Exam Category/Exam 
Calc, or New Patient. 
BenefitsDepth adjusts your field of view. It increases your field of view to 
look at larger or deeper structures; it decreases your field of 
view to look at structures near the skin line. 
Affect on other 
controlsAfter adjusting the depth, you may need to adjust the TGC,  
focus, and edge enhance. 
Changing Depth,
• Clears CINE memory. 
•  Erases real-time calculations graphics on the display (but 
not the completed results on the worksheet page). 
BioeffectsChanging the depth may change the TI and/or MI. Observe the 
output display for possible effects.
HINTSMake sure enough space is left below the anatomy of interest 
to demonstrate shadowing or enhancement.
