The application discloses a positioning guide and an additive manufacturing method thereof. The positioning guide is used for hip arthroplasty and comprises a positioning base, a main guide structure and first and second guide piles arranged on both sides of the main guide structure. The positioning base comprises first and second fitting parts respectively fitted with local bony surfaces on both sides of a patient's acetabular notch and a connecting part connecting the first and second fitting parts. The main guide structure is arranged on the connecting part and has a guide channel for accommodating a handle of a surgical tool to exert geometric constraint on a placement direction of an acetabular reamer tool. The guide channel is determined according to an acetabular cup designed to a target anatomical position and a simulation handle arranged in association with the acetabular cup. The first and second guide piles are used for guiding the arrangement of Kirschner wires to fix the positioning guide to the acetabular region of the patient, thereby improving the accuracy and stability of acetabular polishing and acetabular cup implantation.

The present application relates to the technical field of digital image processing, in particular to a tumor interstitial proportion quantitative evaluation system based on pathological images. The present application automatically obtains tumor epithelial region, tumor interstitial region, tumor region and tumor infiltration front region based on image segmentation, without pre-selecting histological evaluation position for visual evaluation by artificial selection, avoiding the subjective experience dependence of traditional methods, and improving the efficiency of tumor interstitial proportion evaluation. In addition, the present application comprehensively quantitatively evaluates the first tumor interstitial proportion under the overall scale of the to-be-tested pathological image, the second tumor interstitial proportion under the scale of the tumor infiltration front region and the third tumor interstitial proportion under the scale of the tumor region, and finally obtains the tumor interstitial proportion score value which can reflect the tumor interstitial proportion characteristics of different anatomical positions, further improving the accuracy of the evaluation result. The preset rule is to select the window tumor interstitial proportion with the highest tumor interstitial proportion value.

The method of the present application obtains a chest X-ray image and corresponding text description information, extracts the anatomical position information related to the lesion or abnormality from the text description information, and constructs the region constraint information corresponding to the image space based on the anatomical position information. The chest X-ray image, text description information and region constraint information are input into a visual positioning model to output the target region positioning result corresponding to the text description semantics. The visual positioning model is trained in a semi-supervised learning manner, and a training framework of a teacher model and a student model is introduced in the training process. The region constraint information is used to screen, weight or constrain the candidate positioning results generated in the unannotated samples, so as to improve the quality of the pseudo labels and thus improve the accuracy and stability of the target region positioning.
