8.EFV
8. EFV Optional SOP-ALPHA6-1 and EU-9132 are necessary. By using the EFV (Extended Field of View) mode, it is possible to carry out observations that are too wide in scope to fit on a single screen when using regular B mode. By moving the probe over the body surface, monochrome and color slice images are acquired, constructed, and displayed as a single image that spreads farther than the field of vision. These are EFV images. Color EFV images consist of the construction and creation of Flow mode and Power Flow mode sectional images. Besides images constructed by parallel scanning of probes, EFV can be used to delineate and display in an arc shape bulging internal organs.
Probes enabled for this function are UST-5413, UST-568, UST-9123 and UST-9127. To effectively implement the EFV mode, it is necessary to assign Extend F-View in advance to the touch panel menu using the Menu-USER SW screen of the Preset Set-Up menu. It is possible to assign functions using Preset on the touch panel menu and panel. [Remark] During EFV operations, restrictions are placed on the operations of the image adjustment functions. Carry out EFV functions after image adjustments have taken place. [Remark] The process of image construction is very sensitive to brightness variations in the sectional images generated by probe scanning. Always carry out operations while being duly careful of the brightness level. Satisfactory image construction may not occur when there is a radical change in brightness.

Basic operation procedure [Remark] Make sure to spread ample echo gel over the area to be examined in advance. After setting STC and Gain to assure that the center of the image is always satisfactorily illuminated, carry out scanning. If the center of the image is dark, image construction processing may not be carried out satisfactorily. When color images are to be constructed and displayed as EFV images, set the Flow Area wider in advance. If the Flow Area is too narrow, the instrument will automatically expand it at the time of EFV function startup. When capturing Color image, turn on EFV when Color is on. When EFV is turned On, the Color on/off and adjustment of Flow Area cannot be performed.
<Operation method> (1)

9.Real Time Doppler Auto Trace
9. REAL TIME DOPPLER AUTO TRACE Optional SOP-ALPHA6-3 is necessary. Real Time Doppler Auto Trace is a function that detects the R-wave of the ECG during a real-time D mode display, calculates the subsequent Doppler information corresponding to the latest heartbeat, automatically traces a Doppler waveform, and displays the results on the screen. An automatic trace can also be performed immediately after the image is frozen. In addition, the calculated doppler information can be transferred to an applied measurement. [Remark] It is necessary to assign D.Trace on the touch panel menu beforehand. For the setting method, refer to Section 7. "PRESET".
Note To improve measurement accuracy, observe the following safety measures when using this function. 1. For a measurement object image and a blood vessel. Preferably, use it with a beat waveform of peripheral vessels artery such as the carotid artery. •When the result of an operation of Real time Doppler Auto Trace is not suitable, perform auto and manual trace of a measurement function after freeze. •When PI and RI are calculated using this function, the minimum flow velocity point during a single heartbeat is EDV. In the case of a waveform in which the polarity of the blood flow changes during the interval between the systole and the diastole, as is the case with the arteries of the lower extremities, the peak of the waveform that has undergone a polarity change is detected as EDV. 2. For Doppler waveform drawing condition settings This function is activated based on Doppler signals, so the quality of the image signal created affects the measured values to a certain extent. Optimize each setting so that an accurate Doppler waveform is displayed. -Setting a velocity range Set so that aliasing does not occur. -Setting of Dop Filter In PI/RI measurement, the mean flow velocity is calculated. The mean flow velocity is calculated for all flow velocity components corresponding to the latest heartbeat, so an excessively small evaluation index will be made in the case of a Doppler waveform whose low velocity component is missing, such as when Dop Filter is applied to an excessive degree. Note that this will also affect the value of PI. -Setting of Dop Gain Adjust the DOP gain in such a degree as no noise is distinguishable -Setting of Angle compensation Use a Doppler waveform set on an Angle compensation.

Display of an operation Result
• An R-wave search line cursor, a trace line When an ECG signal is displayed, a line cursor is displayed by the timing detecting R-wave. When the image is frozen, a line cursor is displayed by the timing detecting R-wave. The method of trace is the Peak method. [Remark] You can change dB value with D. Trace Level of menu to adjust the trace line. • Display of an operation result In the arithmetic processing of the measured value, the Doppler information for the latest heartbeat based on the R-wave information is calculated, and the measured values of PI, RI, S/D, PSV, EDV, and so on, are displayed. [Remark] When a doppler waveform which is necessary for a measurement is not obtained properly, it is displayed as “***”. [Remark] The display of a measurement value is updated whenever a new R-wave is recognized (the latest heartbeat is updated) in real time. [Remark] While an image is frozen, it is updated when the trace line is redrawn, or when the “latest heartbeat on the screen” changes as a result of a scroll search, a change in the sweep velocity, or a request operation. In addition, a measured value is not displayed on the screen when there is no effective heartbeat detected by these operations. [Remark] The items comprising the results of an arithmetic operation can be selected by using D.Trace Display Items in preset.
