We developed a reflectance continuous-wave near-infrared spectroscopy topography system with multi-source and multi-detector sensor head. A single wavelength (808 nm) laser diode is used as the original light source. With different-measurement approach, we can reconstruct images representing the variety of cerebral blood volume in clinical applications. Phantom experiments have been taken to verify...
The aim of this study is to investigate the upper limit of protection afforded by various protective equipment and techniques that used in combination and used individually. A multi-element, nonlinear mathematical model, which was previously used to produce cardiovascular response to +Gz stress and protection afforded by anti-G suits, was modified by incorporating pulmonary-respiration model, as well...
Liver kinetic study of [18F]2-fluoro-2-deoxy-D-glucose (FDG) metabolism in human body is an important tool for functional modeling and glucose metabolic rate estimation. In general, the arterial blood time-activity curve (TAC) and the tissue TAC are required as the input and output functions for the kinetic model. For liver study, however, the arterial-input may be not consistent with the actual model...
Balloon configuration and control scheie are iiportant for the optimization of the assist to the failing heart Kith IABP. In this Hork, the configuration of lulti-chaiber balloons and their control scheies have been investigated by using a heiodynaiic lodel and computer simulation lethods. Results show that the optiial configuration and controlled lulti-chaibered balloon can provide better assist...
