| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Fluorescent X-ray CT (FXCT) can be a high-resolution molecular imaging, since it can detect a very small amount of imaging agent, such as iodine, with high resolution of a few hundreds of micrometers. Presently, it takes about 60 minutes to in vivo image a rat’s head with a spatial resolution of 0.5 mm because of use of a data-acquisition scheme by a thin beam, which is the same as that of the first generation of CT. Therefore, iodine quantity in the brain decreases due to metabolism by approximately 10 to 20％ during the measurements, leading to a deterioration of quantitative estimation. In this study, based on a phenomenological mode proposed, we devise a correction method for the temporal attenuation of iodine concentration in in-vivo FXCT imaging, and demonstrate its efficacy using simulation data. | |
