Ultrasonic automatic scanning device and imaging method thereof

Abstract

Provided are an ultrasonic automatic scanning device and an imaging method thereof. The device comprises a housing, a drive, a transverse guide, a transverse slider, a transverse encoder, a longitudinal guide, a longitudinal slider, a longitudinal encoder, a pressure sensor and a spring. The transverse slider is mounted on the transverse guide; the longitudinal guide is mounted on the transverse slider; the longitudinal slider is mounted on the longitudinal guider; the pressure sensor is mounted on the top of the longitudinal guide; the spring is set between the longitudinal slider and pressure sensor; and an ultrasonic probe is mounted on the outer side of the longitudinal slider. Automatic scanning has the advantages of being subject to feedback the pressure of a ultrasonic probe, maintaining a moderate pressure and improving the accuracy of the diagnosis through the pressure sensor; performing pressure to the ultrasonic probe through the spring, having an adaptive function of compression, and being applied to scan the flat or concave-convex parts of the human body. A data reconstruction and a three-dimensional ultrasound volume imaging are performed based on ultrasonic scanning line data and moving trajectory, which solves the difficult problem of three-dimensional ultrasonic volume imaging of handheld ultrasound scanning device.

Description

technical field [0001] The invention relates to an ultrasonic inspection device, in particular to an ultrasonic automatic scanning device and an imaging method thereof. Background technique [0002] In traditional handheld ultrasound scanning, the doctor holds the scanning device to press and move on the human body for scanning, which greatly depends on the doctor's operation, and it is easy to cause inconsistency or missed diagnosis due to differences in the doctor's operation techniques and coverage areas . [0003] In addition, the pressure of the probe cannot be fed back, and the intensity of compression cannot be controlled through pressure feedback. It can only rely on the doctor's experience, which may easily lead to inaccurate scan results. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automatic ultrasonic scanning device and its imaging method. This automatic ultrasonic scanning device and its imag...
