Ultrasonic array substrate, driving method, detection system and application method

Abstract

The invention discloses an ultrasonic array substrate, a driving method, a detection system and an application method. The ultrasonic array substrate in one embodiment comprises sensor groups arranged in an array, a first row gating signal line and a first column gating signal line, wherein the first row gating signal line and the first column gating signal line are used for gating the sensor groups; each sensor group comprises sensing units arranged in an array, a second row gating signal line and a second column gating signal line for gating each sensing unit, and a reading signal line, and each second column gating signal line is electrically connected with the reading signal line; and the sensing unit responds to the first row gating signal line and the first column gating signal line to gate the sensor group to which the sensing unit belongs, and responds to the gating of the second row gating signal line and the second column gating signal line to transmit a received echo signal to the reading signal line through the second column gating signal line. According to the embodiment of the invention, the problems of too high signal acquisition frequency, high sensor density and many leads in array ultrasonic imaging can be solved, and the method has practical application value.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic array substrate, a driving method, a detection system and an application method. Background technique [0002] The existing ultrasonic medical imaging probe is a focusing probe. The ultrasonic signal emitted by the probe is reflected by the human tissue and then the ultrasonic echo signal reflected by the corresponding position of the probe is received. Based on the echo time and amplitude information and the movement of the probe, the human tissue can be imaged. This type of solution has fewer array element channels, relatively mature technology, and easy signal acquisition. [0003] However, during use, the ultrasonic medical imaging probe requires medical personnel to constantly move the probe to detect the area to be detected, which is time-consuming and laborious, and different medical personnel operate differently, and the detection results are easily affe...
