The level extractor 2 #i inputs the ultra-f wave echo data stored in the ultra tags memory 20, and extracts the ultra-frN and ultra-tm within a certain echo level range 8 specified by the volume R of the echo data. The echo data t-11!4 is converted into white level data as shown in Figure 4. The comparator 6 inputs the output of the level extractor 2, and outputs one pulse for each piece of white level data only when white level data is input. ] The output pulses are counted and cleared each time one screen of display on the television monitor 21 is completed.

The area calculation unit 5 is a pROM (programmable RO
M), and outputs the area value stored at the n address specified by the output of the counter 4 to the character generator 24. In this case, one piece of white level data is one pixel (
Also, the extent to which one pixel corresponds to an area (-'')K within a living body is uniquely determined by the field of view width and viewing depth of the hyperfontograph. Therefore, the FROM of the area calculation unit 5 contains the pixel→−
For example, the 0 mask generator 6 that stores a data table for converting the data into the joysticks A, B, and C.

By operating Dt, a horizontal mask signal (H-NASA signal) 22 and a vertical mask signal (V-MASK No. 5) as shown in Figure 411M5 are generated, which are processed as display signals and sent to the counter 4. nt is output and serves as a suppression signal for counting by the counter 4.

In addition, in FIG. 3, 25 is an ultrasonic probe, and 26 is an ultrasonic probe om*a in the ultrasonic glove 25.

This is a mixer that combines the area #t#I result of a predetermined part in the IIS, and the one shown at 32 converts the digital signal output from the mixer 31 into an analog signal, and outputs the output to the TV monitor 21. It is a D/A converter. The character generator 24 generates Ii! based on the data output from the pROM 5. jS Outputs data corresponding to display characters (numbers).

Next, we will describe the action of the ferrule 1 configured above.

111, the ultrasonic echo data is read out from the memory 20, and an ultra-f beast cross section as shown in FIG. 6 is displayed on the television monitor 21. In Figure 6, 66 indicates the primary color of the normal specimen.The pus capsule is filled with uniform substances such as lymph fluid and serum, so in the ultra-f Ogi tomography system, the primary color 33 is uniform. Appears as an echo.

Therefore, the area # of the primary colors 36 shown in the ultra-f-diameter image is imaged as follows. That is, the ultrasonic echo data extracted from the ultrasonic wave guiding memory 20 is 31, and is also output to level extraction 42.

The MASK signal and the H-MASK signal are output to the counter 4 as count suppression signals. Input to counter 4
Only those pulses belonging to the mask 64 are counted by the count suppression signal, and a count address n1 is output to the area calculation unit 5. The area calculation unit 5 reads out the area value corresponding to the count address, and outputs the area value to the character generator 24.

Note that reading of the area value by the FROM in the area calculation unit 5 is completed within 1 μzmc.

The character generator 24 converts the manually input area value into a signal indicating characters, for example, numbers, and outputs this to the mixer 61. The 0 mixer 61 combines the ultrasonic echo data and a signal that converts the area value into numbers. Via the D/A converter 32, the mta cross section ml soft cross section and its ultra fl IL cross section are displayed as the area values of the primary colors shown in n and t on the television monitor 21.
