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.

The factory default preset selections are displayed on the Touch Panel. A typical example for the Abdomen exam category is shown below. Figure 4-6. Abdomen Preset Selection Touch Panel Use these parameters as a starting point for the exam.
Beginning an Exam LOGIQ 5 Basic User Manual 4-11 Direction 2300002-100 Rev. 2 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.

LOGIQ 5 Basic User Manual 5-1 Direction 2300002-100 Rev. 2 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 the Image 5-2 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Optimizing B-Mode Intended Uses B-Mode is intended to provide two-dimensional images and measurement capabilities concerning the anatomical structure of soft tissue. Figure 5-1. B-Mode Display
Optimizing B-Mode LOGIQ 5 Basic User Manual 5-3 Direction 2300002-100 Rev. 2 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.

Optimizing B-Mode LOGIQ 5 Basic User Manual 5-5 Direction 2300002-100 Rev. 2 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.
Optimizing the Image 5-6 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 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.
