Abstract

The invention discloses a mammary gland three-dimensional ultrasonic CT imaging system based on a high-density CMUT cylindrical array, and relates to the field of MEMS sensors. The system comprises aCMUT cylindrical array detector, a configuration circuit, a computer control system and a detection bed, wherein the CMUT cylindrical array detector is assembled by 512 rows of annular arrays, 2048 CMUT array elements are distributed on each row of annular arrays at equal intervals, and the CMUT array elements are manufactured by adopting a micromachining technology taking silicon-silicon bondingas a core. The CMUT cylindrical array surrounds the periphery of the breast for three-dimensional full-automatic electronic scanning, and has good cost and performance advantages in the field of ultrasonic imaging. The mammary gland three-dimensional ultrasonic CT imaging system is reasonable in design, can effectively improve the resolution of mammary gland ultrasonic tomography, shortens the detection time, has the characteristics of high sensitivity, high specificity and low cost, and has good practical application and popularization values.

Description

technical field [0001] The invention relates to the technical field of MEMS sensors, in particular to a breast three-dimensional ultrasonic CT imaging system based on a high-density CMUT cylindrical array. Background technique [0002] In recent years, ultrasound computed tomography (USCT) has developed rapidly as a new type of breast cancer imaging technology. It is mainly based on breast cross-sectional tomography. ; At the same time, it uses the characteristics of good ultrasound penetration, and the attenuation coefficients of different tissue densities in the breast vary greatly, so it has high density resolution characteristics, which is far superior to X-rays, and can distinguish small calcification points. Relying on the rapid data processing technology of the computer, USCT can realize three-dimensional dynamic high-resolution imaging, and at the same time, the ultrasound is safe and reliable, and can be measured multiple times in a short period of time. [0003] H...
