Mammary gland electrical impedance scanning imaging hand-held detection probe body surface positioning system and method

Abstract

The invention discloses a mammary gland electrical impedance scanning imaging hand-held detection probe body surface positioning system and method, which comprises a probe, a reference scale, a probeidentification label, a camera device and a computer; when the reference scale is used, the reference scale is arranged in a detection area and is used for providing standard size scale information; the probe identification label is arranged on the upper surface of the probe and forms a fixed corresponding position relation with a detection electrode array; the camera device is used for acquiringvideo and image information of the detection probe and the detection area; and the computer carries out real-time processing on the image information acquired by the camera device, accurate positioning of the detection area and tracking of the moving track of the probe are achieved by using an image identification and optical flow tracking algorithm, and the electric impedance information of the area where the probe is positioned is synchronously acquired. The synchronous acquisition of the impedance information and position information of the EIS detection target area can be achieved, accurate body surface positioning information can be provided for the EIS detection, and the positioning information of the probe on the target area can be ensured to be consistent when the EIS detection target area is reviewed for a plurality of times.

Description

technical field [0001] The invention relates to a positioning method for a hand-held detection probe, in particular to a body surface positioning system and method for a hand-held detection probe of breast electrical impedance scanning imaging. Background technique [0002] Breast electrical impedance scanning (EIS) technology usually uses a hand-held probe to check the health status of women's breasts. The hand-held probe has the advantage of flexible operation. probing. However, the disadvantage of the hand-held probe detection method is that it is not conducive to standardized control of the operation process. This makes it difficult for the operator to ensure that the position of the probe is consistent each time when a certain area of ​​the breast is repeatedly inspected, so that the images obtained each time are different, which is not conducive to the comparative analysis of a series of images. In clinical practice, it is usually necessary to conduct comparative exa...

Problems solved by technology

[0004] Due to the use of hand-held detection probes in the existing breast electrical impedance scanning (EIS) technology, it is difficult to achieve repeatable and accurate positioning of the target area of ​​interest during the review process, which is not conducive to periodic dynamic monitoring of changes in lesion status. Technical problem, the object of the present invention is to provide a breast electrical impedance scanning imaging handheld detection probe body surface positioning system and its method
