Problems solved by technology

[0005] Publication number CN108143487A discloses a method for determining the center point of the ankle joint, which includes performing CT imaging and three-dimensional reconstruction of the lower limbs of the human body; perfusing the three-dimensionally reconstructed ankle joint space through 3D modeling software; finding the center point of the perfused body , which is the center of the ankle joint. The device performs three-dimensional modeling through CT molding. Medical imaging is mainly black, white and gray. The post-processing of data acquisition needs to combine three directions to determine a point. For the determination of the volume, the amount of collected data Big

Embodiment Construction

[0028] The steps of a method for establishing a 3D digital model of the ureter using imaging in the present invention are as follows:

[0029] 1) The patient lies on a flat platform, stays still during the whole process, and the waist and abdomen are expanded and flattened;

[0030] 2) The ureteral 3D digital-analog data acquisition device using imaging is used to collect images from three directions to obtain the three-dimensional data of the ureter: use X-ray to collect two-dimensional images to obtain the two-dimensional image data of the ureter;

[0031] 3) The two-dimensional image data in step 2 is transferred to the computer, and the image processing software is used to extract noise and image pixelation processing, so that the two-dimensional image forms a dot cloud image according to the image color difference and brightness;

[0032] When performing bitmap cloud image analysis, the corresponding point color brightness is used for hierarchical screening. When the color brightn...

Abstract

The invention discloses a ureter 3D digital-analog establishing method adopting iconography and a data acquisition device thereof. The method is characterized in that X-ray scanning images are acquired in multiple directions; brightness analysis is carried out on the image to form a point location cloud chart; the ureter 3D digital model is constructed through fitting of the point position cloud picture, multi-directional continuous collection is achieved, data coverage is comprehensive, accurate and stable, dot matrix composition is achieved, the ureter surface structure can be clearly displayed, details can be conveniently known, the body surface of a human body in a collection area is smooth, foldover is reduced, the structure is simple, and use and installation are convenient.

Description

Technical field [0001] The invention relates to a method for establishing a 3D digital model of the ureter using imaging and a data acquisition device thereof, and relates to a method for establishing a 3D digital model of a patient's ureter in a medical process and a data collection method for constructing the digital model thereof, belonging to medical treatment Equipment field. In particular, it relates to a method and a collection device for acquiring X-ray scan images in multiple directions, analyzing the brightness of the images to form a point cloud map, and constructing a 3D digital model of the ureter by fitting the point cloud map. Background technique [0002] At present, in the diagnosis of diseases in the urology department, the interns are directly operated on the patient under the knowledge of the doctor’s instructor. The learning cycle is long and the risk is high. The direct operation of the ureter on the patient brings risks to the patient. As well as pain and ...
