Computer breast scanning automatic machine positioning system

Abstract

The invention discloses a computer breast scanning automatic machine positioning system, wherein a self-rotation angle encoder is installed between every two neighboring mechanical arms, and is used for measuring a relative rotation angle in a space between two mechanical arms, and sending to a processor. A mechanical arm probe is connected with one of the end parts of multiple mechanical arms, and is used for scanning the breasts in the different space positions, and transmitting a scanned image to the processor. The processor is used for recording manual calibration left / right AP positions and a nipple image initial position, and according to the space relative rotation angle of each mechanical arm corresponding to the mechanical arm probe in each different space position, determining the image positions obtained by scanning in the different space positions and the displacement of the nipple in the image. The computer breast scanning automatic machine positioning system is capable ofaccurately, efficiently and automatically determining the image position in the scanning image obtained in a moving scanning process of the ultrasonic scanning probe and the nipple image displacementinformation, and the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the technical field of ultrasonic scanning systems. Background technique [0002] With the advancement of medical and related technologies, ultrasonic scanning systems are more and more widely used in the medical field, especially in breast health and other fields. At present, when an automatic breast ultrasound scanning system is used to scan a breast, a three-dimensional image of one automatic scan can cover a part of the breast. In diagnosis or screening, in order to cover the entire breast, the operator usually needs to place the full-volume manipulator probe at three locations on the breast to obtain three 3D images to cover the entire breast area. These three positions are often referred to simply as "AP", "MED" and "LAT" (see figure 1 ). [0003] The three-dimensional image obtained by scanning the breast with the automatic breast ultrasound scanning system will also ...

Problems solved by technology

Currently, neither academia nor industry has a system for automatically marking the position of the full fusion ultrasound scan and the location of the nipple

[0004] On the other hand, on the tracking marker module, the traditional electromagnetic-based tracking technology has high cost and low accuracy

However, the existing video-based tracking technology often has poor tracking or detection effects due to its inability to adapt to different light and complex targets.

[0005] Therefore, in general, in the current breast ultrasound scanning system, it is still impossible to accurately and efficiently determine the displacement of the nipple in the scanning image obtained by scanning the moving probe, that is, the nipple image. displacement
