Disease detection instrument

The utility model discloses a disease detection instrument, belonging to the field of medical instrument manufacturing technology. The disease detection instrument comprises a CT (Computed Tomography) scanner, a computer processor and an edge detector, wherein a signal output end of the CT scanner is connected with a pin 2 of the processor, a pin 15 of the computer processor is connected with an output end of the edge detector. Edge detection can be achieved by obtaining CT pictures, preprocessing the CT pictures and extracting edges. The disease detection instrument can establish a three-dimensional model of human organs, obtain CT two-dimensional picture, process the two-dimensional picture by utilizing an edge recognition and three-dimensional outline extraction software, recognize the interior and exterior outline of a target tissue, extract data of the interior and exterior outline and a prosthesis outline and establish the three-dimensional model, and can conduct simulation operation to the reconstructe
