Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] The embodiment of the present invention discloses an ultrasonic directional and constant temperature heating method based on a circular array. The application scenario of this method includes the thermal therapy of the tumor area in the treatment of cancer. Using this solution to heat the tumor area can avoid the traditional hyperthermia process. The use of nuclear magnetic resonance for temperature detection and control is costly and has radiation, which will cause additional radiation damage to the human body. The use of ultrasonic equipment in this scheme is low in cost, and at the same time, ultrasonic waves have no radiation damage to the human body, which is easy to control and operate.

Abstract

An embodiment of the invention discloses an ultrasonic directional constant-temperature heating method based on an annular array. The method comprises the steps of transmitting an ultrasonic signal toa target space through the annular ultrasonic sensor array, collecting the ultrasonic signal, reconstructing a B-type ultrasonic image of the target space, and obtaining position information of a heated target through analysis of the B-type ultrasonic image; heating the target by focusing ultrasonic energy on a target position; reconstructing a sound velocity distribution image in a target area through the annular ultrasonic sensor array, and then calculating out temperature distribution in the target area; and adjusting an energy value of focused ultrasonic waves according to a calculated target area temperature feedback, and increasing the heating power in a stepped mode so as to achieve the function of quantitatively controlling the temperature. Compared with the prior art, the targetarea is not damaged or radiated, and meanwhile the equipment cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging and processing, in particular to an ultrasonic directional constant temperature heating method based on a circular array. Background technique [0002] Ultrasonic focused heating is a technology that uses the high-energy characteristics of ultrasonic waves to focus multiple beams of ultrasonic waves on the same area to increase the temperature of the medium in this area. [0003] In ultrasonic focused heating technology, if you want to achieve constant temperature heating, you must detect and monitor the temperature of the heating area. Existing ultrasonic focused heating technologies often use plug-in temperature sensors or nuclear magnetic resonance technology for temperature detection and monitoring, but plug-in temperature sensors will cause damage to the target area and cannot detect the temperature in the entire area. MRI, on the other hand, is expensive and radiative. Contents...
