基于CT多期图像融合构建3D打印重复肾模型的应用
Application of Three-Dimensional Printing for Renal Duplication Model Based on Multiphase CT Image Fusion
摘要
Abstract
Objective To explore the clinical value of Three-Dimensional (3D) printing for renal duplication, this present study constructed a 3D printing model based on the multiphase enhanced CT of the abdominal image. Methods One patient with 8 months of right kidney and ureter double malformations was performed 64-slice contrast-enhanced CT reconstruction with iterative algorithm; through importing the DICOM CT data into mimics 17.0 software, the images in arterial phase of the renal artery, vein of kidney images, the delay phase of vesicoureteral image were extracted respectively. Images were segmented depending on the different values of CT and the region of interest was reconstructed to generate stereolithography file data. Then the modeling process was completed after importing the data into OBJET 2603D printer. Results The 3D model was constructed by fusing different phase images in the same model, the anatomical structure of artery, kidney, ureter and bladder were observed. It was of significant importance in the resection of renal duplication and ureter lesion. Conclusion The model based on multi phase CT 3D printing is a very important method to assist the diagnosis and treatment of repeated renal malformations.关键词
