御するようになつている。 In FIG. 1, 1 is a therapeutic transmission pulse control circuit, 2 is a tomographic image transmission pulse control circuit, 3 is a switch control circuit, and 4 is a drive element selection switch.
A drive element selection switch 4 is controlled by a switch control circuit 3 to select between several transmitters 6 connected to each of a large number, for example, 60 to 120 ultrasonic transducers 5 arranged in an array. When more than ten of them are turned on, and a signal from the tomographic image transmission pulse control circuit 2 is added to them, a thin ultrasonic beam as shown at 7 in FIG. 2a is emitted. The reflected ultrasonic beam is detected by an ultrasonic transducer 5, passes through a receiver 8 and a switch 3, and then is sent to a reception delay line 9 and a signal processing circuit 1.
0 as the brightness signal of the TV monitor 11.
input to the monitor. Next, the switch control circuit 3 switches the driving element selection switch 4 so as to shift the ultrasound transducers 5 one by one, and the signal from the tomogram transmission pulse control circuit 2 is added again to change the ultrasound beam. is emitted and the reflected signal is received. By repeating this operation one after another, a linear scan of the ultrasound beam is performed and a tomographic image is obtained. On the other hand, the switch control circuit 3 is connected to the drive element selection switch 4.
All or many of them are turned on, and the therapeutic transmission pulse control circuit 1 applies a driving pulse to drive the transmitter corresponding to each arrayed vibrator. In this case, by delaying the drive pulse to each transmitter by a desired time and generating it in the transmission pulse control circuit, the ultrasonic beam 12 is generated at a predetermined depth and a predetermined beam diameter as shown in FIG. 2b. A focal point 13 is formed with . By controlling the switching control circuit 3, the tomographic image transmission pulse control circuit 2, and the therapeutic transmission pulse control circuit 1 as described above, a scanning ultrasound beam for obtaining an ultrasound tomographic image and a therapeutic ultrasound beam are controlled. The beams can be switched arbitrarily, and the treatment can be performed while observing the tomographic images by alternating them to the extent that the real-time properties of the ultrasonic tomographic images are not impaired. The following cases can be cited as examples of output switching that does not impair the real-time properties of ultrasound tomographic images. That is, 1
The ultrasonic scan time required to obtain one ultrasonic tomographic image is determined by the product of the time it takes for the emitted echo to return after one ultrasonic beam is emitted and the number of scanning lines. For example, Depth of object
If the length is 18 cm and the number of scanning lines is 128, the ultrasonic scan time is approximately 32 msec. Therefore 32msce
After obtaining one ultrasonic tomogram by applying the output of the transmission pulse control circuit 2 for tomographic images to different ultrasonic transducer groups 5 one by one by the switching device control circuit 3, the next 32msec is therapeutic transmission pulse control circuit 1
The output of is applied to the ultrasonic transducer 5 to form the focal point 13, and thereafter, when the output of the tomographic image transmission pulse control circuit 2 and the output of the therapeutic transmission pulse control circuit 1 are alternately switched, Since 15 ultrasonic tomographic images are obtained per second, the real-time properties of the ultrasonic tomographic images are not impaired, and at the same time, treatment can be performed using the focal point 13 of the ultrasonic beam for 0.5 seconds. In this way, the ultrasonic beam generating means 20 is constituted by the therapeutic transmission pulse control circuit 1, the tomographic image transmission pulse control circuit 2, the switch control circuit 3, the drive element selection switch 4, and the transmitter 6. Ru. Reference numeral 14 indicates a caliper control circuit, which displays the caliper 16 at a desired position in the ultrasonic tomographic image displayed on the cathode ray tube 15 of the television monitor 11, as shown in FIG. This circuit outputs a signal indicating the position of the caliper 13 inside to the central processing unit (CPU) 17.
Based on the signal indicating the position of the caliper 13, the central processing unit 17 instructs each ultrasonic transducer 2 to form a focal point 13 of the ultrasound beam at a position within the subject corresponding to the position of the caliper 13. Calculate the delay time for delaying the applied drive signal. The central processing unit 17 also controls the operation of each part of the ultrasonic diagnostic treatment apparatus, and in particular controls the switching device control circuit 3, the therapeutic transmission pulse control circuit 1, and the tomogram transmission pulse control circuit 2. It is designed to control the timing of movements.

An ultrasound probe, a signal processing circuit and a television monitor for scanning an ultrasound beam emitted from the ultrasound probe and displaying an ultrasound tomographic image based on the reflected echo thereof, and a real-time an ultrasonic beam generating means comprising a switching means for switching between an ultrasonic beam for obtaining an ultrasonic tomographic image and an ultrasonic beam for treatment and generating the ultrasonic beam from the ultrasonic probe; and for obtaining the ultrasonic tomographic image. control means for controlling the switching means to generate the ultrasonic beam for the treatment at every predetermined timing of the ultrasonic beam scanning operation of the ultrasonic beam scan operation, and displaying a real-time ultrasonic tomographic image and simultaneously performing the ultrasonic treatment. An ultrasonic diagnostic treatment device characterized by: 2. Ultrasonic diagnostic treatment according to claim 1, characterized in that the ultrasonic beam generating means includes a switching device that causes the ultrasonic probe to generate only an ultrasonic beam for obtaining an ultrasonic tomographic image. Device. 3. The ultrasonic beam generating means sets the caliper at a predetermined position in the ultrasonic tomographic image displayed on the television monitor. Based on the caliper position signal output from the caliper control circuit, the ultrasonic beam generating means sets the caliper at a predetermined location within the subject corresponding to the caliper position. The ultrasonic diagnostic treatment apparatus according to claim 1, wherein the ultrasonic beam is generated from the ultrasonic probe so that an ultrasonic focus can be formed at the ultrasonic beam.
