Three-dimensional ultrasonic tomography data acquisition device based on sitting type array and linear array

Abstract

The invention relates to the technical field of medical equipment, and particularly discloses a three-dimensional ultrasonic tomography data acquisition device based on a sitting type array and a linear array. The device comprises a soft sleeve, the linear array, a sliding rod, a control module and a sealing groove, and the soft sleeve sleeves the mammary gland, so that the mammary gland is not greatly deformed due to body position change; linear array combined ultrasonic transducer arrays are distributed around the mammary gland and are connected with the sliding rod; the control module controls the linear array to move from nipples to mammary roots so as to acquire each group of two-dimensional measurement data for reconstructing a three-dimensional image; the sealing groove surrounds the mammary gland, the linear array and the sliding rod, and the lower end of the sealing groove clings to the skin under the mammary gland; and a coupling agent is packed in the inner side gap of the sealing groove and a gap between the soft sleeve and the mammary gland. The three-dimensional ultrasonic tomography data acquisition device can realize data acquisition during sitting or standing, overcomes the defects of high annular array processing difficulty, high cost, inaccurate matching between array analog position and digital coordinates and the like, and has an actual application value for breast cancer screening based on ultrasonic tomography.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a three-dimensional ultrasonic tomography data acquisition device based on a sit-stand and linear array. Background technique [0002] Breast cancer is one of the common malignant tumors in women. Early detection and early treatment is the best way to save patients' lives, therefore, early screening of breast cancer plays a pivotal role. [0003] Compared with X-ray Computed Tomography (X-ray Computed Tomography) and Magnetic Resonance Imaging (Magnetic Resonance Imaging), Ultrasound Computed Tomography (USCT) has no ionizing radiation, non-invasive, no need for breast compression and cost It is a promising method for early screening of breast cancer. [0004] Studies have shown that different types of cancerous tissues and normal tissues can be identified by combining the tissue sound velocity distribution map reconstructed by USCT with prior knowledge.
