Biplane ultrasonic image planning method and device

Abstract

The invention discloses a dual-plane ultrasonic image planning method, and solves the problem of large path planning error of the existing method. The method comprises the steps that the position relation between a first ultrasonic probe and a cross section image is calibrated, a first conversion matrix is obtained, and the first conversion matrix is a matrix converted from a cross section image coordinate system to a first ultrasonic probe coordinate system; calibrating the position relationship between the first ultrasonic probe and the sagittal plane image to obtain a second conversion matrix which is a matrix converted from a sagittal plane image coordinate system to a first ultrasonic probe coordinate system; and calculating a third conversion matrix and / or a fourth conversion matrix by using the matrix conversion relationship, the third conversion matrix being a matrix converted from the cross section image coordinate system to the sagittal plane image coordinate system, and the fourth matrix being a matrix converted from the sagittal plane image coordinate system to the cross section image coordinate system. The invention further comprises a device applying the method. The method is particularly suitable for operation scenes such as urinary surgery intervention, particle implantation treatment and tissue resection.

Description

technical field [0001] The invention relates to the technical field of medical electronics, in particular to a method and device for planning a biplane ultrasonic image. Background technique [0002] Dual-plane ultrasound probes can be commonly used in urology and anorectal surgery. Transrectal ultrasound (TRUS) examination includes high-resolution two-dimensional image display technology and color Doppler technology. Transrectal dual-plane probe examination, the ultrasound frequency High, high-resolution images in two directions can be obtained, clearly showing the characteristics of blood flow distribution in the prostate and the intensity of echoes. When performing surgery, the doctor needs to obtain ultrasound images in two different directions (transverse and sagittal planes) through the transrectal dual-plane ultrasound probe, and the doctor can identify and manually mark the spatial position by reading the images of the transverse and sagittal planes respectively , o...
