Three-dimensional printing method based on synchronous development of renal vessels and renal collecting system

Abstract

The invention relates to the technical fields of imaging and processing of medical organ images, in particular to a three-dimensional printing method based on synchronous development of renal vesselsand the renal collecting system. The method comprises the following steps of a, conducting three-phase scanning on the whole body of a patient by using a CT scanner; b, conducting first-phase scanning; c, conducting second-phase scanning; d, conducting third-phase scanning; e, tracing and triggering scanning by using a CT threshold value, wherein when a CT value reaches the set threshold value, automatic scanning is triggered, the trace point is the renal artery plane descending aorta, the threshold value is 110 Hu, the scanning time is 8-10 seconds, and first to fourth levels of the renal artery are shown; f, obtaining a Dicom file; g, reconstructing the Dicom file through data processing, and obtaining a 3D organ data model; g, obtaining a file in the STL format, and printing a 3D humanorgan model through a 3D printer. According to the method, the synchronous development technology is combined with the 3D printing technology to print the 3D organ model, and an effect and practical clinical significance is provided for clinical teaching, surgery simulation and personalized medicine of the urinary surgery.

Description

technical field [0001] The invention relates to the technical field of organ medical image imaging and processing, in particular to a 3D printing method based on synchronous development of renal blood vessels and renal collection system. Background technique [0002] 3D printing of human organs is an emerging technology that has developed rapidly in recent years. Its application in clinical and medical research has attracted extensive attention from the medical community, especially in the study of human organ structures, which has great social value and development potential. The stability, precision and materials of printing are still not perfect. In terms of manufacturing process, the surface step error and shrinkage deformation of the model make the appearance of the model organ rough, and different tissues or cells have similar physical densities, resulting in similarities in the image. The grayscale, CT will lose more useful information after the acquired data is conve...

Problems solved by technology

However, technically, each inspection is relatively independent, which takes a long time, and the grayscale data cannot be obtained at the same time, so that the renal pelvis, ureter, blood vessels, and lesions cannot be visualized at the same time, resulting in incomplete modeling data. The absence of the three-dimensional spatial relationship between the two cannot be displayed at the same time, and the clinical significance is lost, which makes reverse engineering difficult. The relationship between the blood vessels of the kidney, the renal collecting system and the lesion is not clear when printed, which is a great opportunity for doctors. Accurate diagnosis and targeted treatment plan bring many adverse effects
