In this paper, a new practical implementation of a person verification system using features of longitudinal section and transection and other facial, rotation compensated 3D face image, is proposed. The approach works by finding the nose tip that has a protrusion shape on the face. In feature recognition of 3D face image, one has to take into consideration the orientated frontal posture to nor...

Advances in chemistry and physics have profound effects on neuroimaging. Current and future progress in these disciplines will continue to aid in efforts to visualize neural circuitry, particularly in deeper layers of the brain.

ABSTXACT This paper describes the study of the possibility of x-ray stress measurement in which stresses are obtained by analyzing the whole of one diffraction ring detected with a two-dimensional x-ray detector called an imaging plate (IP). The theory of the stress determination proposed by Taira et al (1978) was shown and advanced to make measurable all plane stress components. The experiment...

Two canonical representations for regularization of unit sphere functions encountered in the context of high angular resolution diffusion imaging (HARDI) are discussed. One of these is based on spherical harmonic decomposition, and its one-parameter extension via Tikhonov regularization. This case is well-established, and is mainly reviewed for the sake of completeness. The second one is new, a...

Imperfections in the spotlight: fluorescence microscopy was used to detect defects in metal-organic frameworks formed during synthesis. In contrast to currently available techniques, confocal fluorescence microscopy offers the advantage of three-dimensional imaging at the single-crystal level combined with the sensitivity required to study the start of defect formation.

The purpose of this study is to compare three-dimensional conformal radiotherapy (3D-CRT) plans in a setting of salvage radiotherapy after radical prostatectomy (RP) and to simulate whether dose escalation is possible with the most adequate 3D-CRT technique. This study included consecutive 10 patients underwent salvage radiotherapy (RT) for biochemical relapse of prostate cancer after RP. Norma...

In recent years, radiotherapy for liver cancer has accomplished much technical progress. The history of radiotherapy for liver cancer shows an endeavor to overcome the problem of how to raise the irradiation dose to lesions while suppressing the unnecessary irradiation dose to normal liver tissue. With the appearance of treatment using X-ray radiotherapy represented by three-dimensional conform...

introduction: raising the knowledge of skeletal and soft tissue changes with aging has been highly essential due to an increasing demand for aesthetic facial surgery following aging. the aim of this study is to evaluate the three dimensional computed tomographic images and process of changes in mandible with aging. materials and methods: in this descriptive study, the facial ct scans were obtai...
