This invention relates to the field of medical imaging diagnostic technology, specifically to a method and system for precise localization of small lesions in the breast and thyroid glands based on AI multimodal imaging. The method includes the following steps: acquiring ultrasound, X-ray, and magnetic resonance images of the breast and thyroid glands; extracting anatomical spatial location and imaging direction; calculating and mapping multimodal pixel spatial offsets; calculating scale consistency and normalizing response intensity based on co-located pixels; comparing multimodal intensity differences to assess consistency and form a scoring distribution; combining the score and intensity to adjust conditional probabilities; calculating joint probabilities and selecting spatial aggregates to locate small lesions. In this invention, by uniformly calibrating the spatial location and imaging direction of multimodal images, precise correspondence between different images at the same anatomical location is achieved. Multimodal response intensities are fused and consistency assessment is performed. Combining probability weight adjustment and spatial aggregation weakens the influence of noise in single images, enhances the common expression of small abnormal areas, and improves the stability and consistency of lesion localization.

This utility model relates to the field of medical device technology, and in particular to a device for locating small lesions, comprising: a positioning structure, which includes a titanium clip, a sleeve, and a guidewire; the first end of the titanium clip is a clamping end, and the second end of the titanium clip is a traction end; the clamping end extends from the first end of the sleeve; the portion of the titanium clip between the clamping end and the traction end is slidably connected to the sleeve; the traction end is connected to the first end of the guidewire, and the second end of the guidewire extends from the second end of the sleeve; the surface of the sleeve has a luminescent material that can emit light when excited by a light source; and an insertion structure, which includes a catheter, a working handle, and a handle; the first end of the catheter is connected to the second end of the sleeve, and the second end of the catheter is connected to the working handle; the handle is mounted on the working handle and is slidable relative to the working handle; the second end of the guidewire passes through the catheter and is connected to the handle. This utility model is at least beneficial for improving the positioning accuracy of lesions in minimally invasive surgery.
