With the continuous development of computer technology, computers have become an indispensable control for ultrasonic high focus piezoelectric treatment systems. In the actual treatment process, the target should be tracked and monitored in the real time through the computer! The target is compared with the treatment plan, and computer-assiszted intervention is performed according to the difference between the two to ensure accurate positioning; The ultrasonic power and the action time are automatically adjusted to ensure the therapeutic effect. How to evaluate the therapeutic effect of HIFU is a difficult problem that must be solved. For the ultrasonic hifu piezo transducer treatment system, the images of the lesion tissue before and after ablation should be distinguished, and the therapeutic effect should be evaluated by means of gray histograms to ensure the effectiveness and safety of HIFU. The HIFU treatment system is a non-invasive treatment device with the high positioning requirement. Because the focal spot is small, it is necessary to scan for large-volume tumors, so the scanning accuracy is very high. In addition, the complexity of the human tissue structure and the tumor site and morphology also affect the accurate treatment. Many experimental results also indicate that HIFU technology.

The planetary deceleration technology can make the scanning precision reach 0.01mm, and then use the medium and high-grade B-ultrasound and hifu piezo transducer speaker treatment system to form IC parts,which is guiding the positioning image the target tissue, and implement the monitoring effect. For the first time, we introduced 3D reconstruction technology of ultrasound images in the 250Khz hifu piezo ceramics treatment system, which can track and monitor the treatment effect in the real time through various methods, and adopt various forms of parameter compensation technology to ensure the safety and effectiveness of tumor treatment. It is 3D reconstruction technology,its arbitrary orientation cutting and browsing images, Effectively solve the inconvenience caused by B-ultrasound in the HIFU ultrasound piezo only observing a sliced image; It is convenient to obtain three views of tumor or normal organs, and measuring 2D size and volume of the basin;For tumors or other organs with a growing direction of confusion, it is more accurate observation and measurement can be performed by cutting and browsing in any direction; The length, width and height of the treated echo enhancement area can be careful analysis of the two-dimensional size is the basis for confirming the therapeutic effect.


Real-time monitoring of grayscale histograms,By monitoring the grayscale histograms of the treatment area, the treatment effect can be effectively judged, and the adjustment of the HIFU transducer piezo ceramic treatment threshold can be provided to ensure the effectiveness of the treatment.it is  real-time tracking and monitoring of the target position ,During the treatment, the computer tracks and monitors are the target position t in real time, comparing the target position with the treatment plan, and automatically compensates according to the difference between the two to ensure accurate positioning and treatment. It is various forms of parameter compensation,Automatically control the output power and duty cycle according to the difference of treatment depth, so as to adjust and perform automatic compensation of x, Y, Z and other directions to ensure treatment.
