For the flexible 3-D visual communication, we have proposed a neutral describing method of 3-D images, based on the ray data. Furthermore, we have proposed a new concept of the “Space Coding” to describe and transmit the whole visual data of a 3-D space. Since the amount of spatial data is very huge, its compression is essential not only for the(More)
The aim of this study was to evaluate 320-row area detector CT (ADCT) for patients with atrial fibrillation (Af) based on simulated exposure using electrocardiogram RR intervals and comparison with the findings of coronary CT angiography (CCTA) using 64-row multi slice CT (MSCT). The probability of including RR intervals of 900 ms or more was calculated(More)
The purpose of this study was to design and construct a phantom for using motion artifact in the electrocardiogram (ECG)-gated reconstruction image. In addition, the temporal resolution under various conditions was estimated. A stepping motor was used to move the phantom over an arc in a reciprocating manner. The program for controlling the stepping motor(More)
