Comparison study on the 3D reconstruction of mandible according to Virtul Chinese Human slice data and CT data
نویسندگان
چکیده
Objective: To resonstruct 3D model of mandible on the basis of Virtual Chinese Human data and normal CT pectures,and to compare their resonstruction results with each other. Methods: To select mandible data from Virtual Chinese Human slices and normal CT pictures, and reconstruct 3D model of mandible respectively by using a modified MC algorithm. Rusults: A 3D model of mandible was reconstructed accurately by adopting virtual human slice data. Conclusions: To reconstruct 3D digital model of human bone by specific software is a beneficial way for our research. The 3D mandible model reconstructed by adopting virtual human slices is more accurate than that by adopting CT pectures.

External radiotherapy of intact breast: A comparison between 2D (single CT- slice) and 3D (full CT-slices) plans
Background: Tangential irradiation of intact breast is one of the most common procedures performed in any radiotherapy center. This method is performed by using 2D and 3D treatment planning. The aim of this study was to compare 2D with 3D plans in breast conserving radiotherapy. Homogeneity of isodose, and lung received dose were compared. Materials and Methods: Twenty patients with br...

Introduction 3D reconstruction of an object from its 2D cross-sections (slices) has many applications in different fields of sciences such as medical physics and biomedical engineering. In order to perform 3D reconstruction, at first, desired boundaries at each slice are detected and then using a correspondence between points of successive slices surface of desired object is reconstructed. Mate...
