Evaluation of the low dose cardiac CT imaging using ASIR technique

Autor: Amy Deubig, Peter Crandall, Jiahua Fan, Jiang Hsieh, Paavana Sainath

Publikováno v: SPIE Proceedings.

Today Cardiac imaging is one of the key driving forces for the research and development activities of Computed Tomography (CT) imaging. It requires high spatial and temporal resolution and is often associated with high radiation dose. The newly intro

Simulation and analysis of image quality impact from single-source ultra-wide coverage CT scanner

Autor: Xiangyang Tang, Thomas L. Toth, Jiang Hsieh, Peter Crandall, Robert Franklin Senzig, Baojun Li

Publikováno v: SPIE Proceedings.

Future generations of CT systems would need a mean to cover an entire organ in a single rotation. A way to accomplish this is to physically increase detector size to provide, e.g., 120~160mm z (head-foot) coverage at iso. The x-ray cone angle of such
