Description
Technical Field
The utility model relates to a sound field sound power calibrating device of medical ultrasonic equipment.
Background
The High Intensity Focused Ultrasound (HIFU) technique focuses ultrasonic waves on a target tissue, focuses the ultrasonic waves generated in vitro on a diseased tissue (a target treatment region) in a living body by utilizing tissue penetrability and energy deposition of the ultrasonic waves, and achieves the purpose of treating diseases through the thermal effect, mechanical effect and cavitation effect of the ultrasonic waves. HIFU techniques focus on phase control of the transmitted ultrasound beams of the individual elements and on energy control of the resulting acoustic field. It is found clinically that it is difficult to control the focus of the ultrasonic beam when the focal point is deep, and there may be cases where the focal region deviates from the focal point, or where the energy in the focal region is too much or too little. This often does not completely remove the tumor tissue and is likely to cause unnecessary damage outside the tumor area.
The ultrasonic surgical system directly acts on human tissues, the size of the ultrasonic output power is an important parameter related to the safe dosage of the ultrasonic into the human body, and although the design purpose of the devices is to destroy the tissues, the devices also have undesirable effect energy of radiation, so the output sound power is a medical parameter which needs to be strictly controlled in the treatment process and is also an important index for evaluating the performance of instruments of the ultrasonic surgical system. It follows that the positioning of the ultrasound focus and the accurate measurement of the focal field acoustic power are of paramount importance, and that periodic verification calibration of the HIFU device is required by hospital institutions.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment includes an industrial camera ①, a base ⑤, a checkerboard background image ⑥, an LED strip lamp ⑦, a water tank ⑧, a sound absorbing cusp ⑨, a fixed bracket ⑩, a motor ⑪, and a scale-marked moving bracket ⑫.
The utility model discloses fix the high strength focus ultrasonic equipment that awaits measuring and sound absorption tip in the water tank both sides. Fixing a checkerboard background image and an LED strip-shaped lamp tube for ultrasonic calibration at the lower side of the water tank, wherein the background image is tightly attached to the bottom of the water tank, and the lamp tube is placed above the background image; the walking mechanism composed of the fixed support and the movable support with scales is driven by a motor, and the motor is connected with the PC end. An industrial camera is fixed at one end of the movable support, the industrial camera is placed above the water tank, and the industrial camera is connected with the PC end through a data transmission line.
The utility model discloses a calibration principle is:
when ultrasound propagates in liquid, the density of the liquid at the part under the action of ultrasound compression will become higher, and the density at the part under the action of stretching will become lower. Because the refractive index of each area is changed along with the uneven change of the density of the liquid, the propagation direction of the light beam is bent in the liquid with the changed density, and further, the background pattern shot by the industrial camera is distorted. When the ultrasonic focal-field sound power is different, the corresponding image distortion degree is also different.
The utility model discloses place high strength supersound focus transducer in the water tank side, utilize HIFU signal generator drive to send the ultrasonic wave. The sound absorption tip is attached to the opposite wall of the water tank and used for absorbing ultrasonic waves to reduce interference caused by ultrasonic reflection. LED strip-shaped lamp tubes are placed around the bottom side of the wall of the water tank to serve as light sources for illumination, and checkerboard background images for ultrasonic calibration are padded on the lower side of the LED strip-shaped lamp tubes. The walking mechanism composed of the fixed support and the movable support with scales is driven by a motor, and the motor is controlled by a PC end. An industrial camera is fixed at one end of the movable support, the industrial camera is placed above the water tank, the industrial camera is connected with the PC end through a data transmission line, and the image processing is carried out on the shot picture to obtain the sound power.
The above, only be the utility model discloses a preferred embodiment, it is not right the utility model discloses do any restriction, all according to the utility model discloses the technical entity all still belongs to any simple modification, change and the equivalent structure change of doing above embodiment the utility model discloses technical scheme's within the scope of protection.
