Algorithm for image reconstruction in multi-slice helical CT.
Efforts are being made to develop a new type of CT system that can scan volumes over a large range within a short time with thin slice images. One of the most promising approaches is the combination of helical scanning with multi-slice CT, which involves several detector arrays stacked in the z direction. However, the algorithm for image reconstruction remains one of the biggest problems in mul...
متن کاملMulti-Slice CT Scanners
In the second half of 1998, four manufacturers (GE, Siemens, Toshiba and Picker, now Philips) extended this concept by launching multi-slice CT scanners. All were 3rd generation helical scanners, with low voltage slip rings, capable of acquiring four CT slices in one x-ray tube rotation (see Fig. 1). Additional four-slice models have been introduced by Toshiba and GE. Some basic specifications ...

متن کاملA Hybrid Method for Segmentation and Visualization of Teeth in Multi-Slice CT scan Images
Introduction: Various computer assisted medical procedures such as dental implant, orthodontic planning, face, jaw and cosmetic surgeries require automatic quantification and volumetric visualization of teeth. In this regard, segmentation is a major step. Material and Methods: In this paper, inspired by our previous experiences and considering the anatomical knowledge of teeth and jaws, we prop...
متن کاملMulti -slice CT Diagnosis of Ectopic Pheochromocytoma
Objective: Analysis of MSCT imaging manifestation of ectopic pheochromocytoma to discuss the value of MSCT in diagnosis of abdominal ectopic pheochromocytoma. Methods: MSCT findings of 10 cases surgically and pathologically proved with ectopic pheochromocytoma were retrospectively analyzed. Results: Soft tissue mass with 12 cases were single tumor. 5 case was located in front of the the abdomin...
