This paper focuses on the development and validation of an optimal motion planning method for computer-assisted surgical training. The context of this work is the development of new-generation systems that combine artificial intelligence and computer vision techniques in order to adjust the learning process to specific needs of a trainee, while preventing a trainee from the memorization of part...

Advancements in computers, prototyping, and imaging, especially over the last 10 years, have permitted the adoption of three-dimensional imaging protocols in the health care field. In this article, the authors present an integrated simulation system for craniofacial surgical planning and treatment. Image fusion technology, which involves combining different imaging modalities, was utilized to c...

An ablation planning system plays a pivotal role in tumor ablation procedures, as it provides a dry run to guide the surgeons in a complicated anatomical environment. Over-ablation, over-perforation or under-ablation may result in complications during the treatments. An optimal solution is desired to have complete tumor coverage with minimal invasiveness, including minimal number of ablations a...

The utilization of computer-aided technologies in tissue engineering has evolved in the development of a new field of computer-aided tissue engineering (CATE). This article reviews recent development and application of enabling computer technology, imaging technology, computer-aided design and computer-aided manufacturing (CAD and CAM), and rapid prototyping (RP) technology in tissue engineerin...

This paper introduces the research project of robot assisted minimally invasive neurosurgery. Using visualization technology, the system reconstructs and displays the 3D model of the patient’s inner structure in the computer. Thus the surgeons can make the surgery planning on the model in the computer. Marker registration is used to create the mapping between the patient’s head and the 3D-brain...

background: total and partial gastrectomy is commonly used to treat gastric carcinoma or other benign or malignant conditions of the stomach. laparoscopic-assisted distal gastrectomy is an alternative approach for treating mucosal gastric cancer. many investigators have assessed the safety, efficacy, and feasibility of this procedure.rnobjectives: the aim of present study is to compare the outc...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...

background and aim: patients who receive hemodialysis need effective education in order to maintain their health. one of the effective methods for education is computer-assisted education. the aim of this study was to compare the impacts of computer-assisted multimedia education and traditional method on clinical parameters of patients receiving hemodialysis. methods: in this interventional stu...
