The three-dimensional graphic method for quantifying body position

Indexing Method for Three-Dimensional Position Estimation

Indexing techniques usually are used in modelbased object recognition and ray tracing algorithms. In this paper we present a new method for estimating the threedimensional position of a subject (resp. object) in a circumscribed space based on an indexing method. We construct two and three-dimensional indices of a space, which are used to estimate the three-dimensional position by an interpolati...

Development of an 123I-metaiodobenzylguanidine Myocardial Three-Dimensional Quantification Method for the Diagnosis of Lewy Body Disease

Objective(s): We recently developed a new uptake index method for 123I-metaiodobenzylguanidine (123I-MIBG) heart uptake measurements by using planar images (radioisotope angiography and planar image) for the diagnosis of Lewy body disease (LBD), including Parkinson’s disease (PD) and dementia with Lewy bodies(DLB). However, the diagnostic accuracy of the uptake index was approximately equal to ...

Nonlinear optical 3-dimensional method for quantifying atherosclerosis burden.

Three-dimensional conformal breast irradiation in the prone position.

The prone position can be used for the planning of adjuvant radiotherapy after conservative breast surgery in order to deliver less irradiation to lung and cardiac tissue. In the present study, we compared the results of three-dimensional conformal radiotherapy planning for five patients irradiated in the supine and prone position. Tumor stage was T1N0M0 in four patients and T1N1M0 in one. All ...

Broken-ray Videometric Method and System for Measuring the Three-dimensional Position and Pose of the Non-intervisible Object

The traditional videometrics technique is usually adopted to measure the relative position and pose between the intervisible objects, and is invalid for measuring the three-dimensional position, pose and deformation of the non-intervisible target. An innovative broken-ray videometrics method is proposed to resolve the non-intervisible measurement problem. Broken-ray path is constructed by relay...
