Development and evaluation of a digital subtraction angiography system using a large-area flat panel detector

Autor: Ken Ishikawa, Shigeyuki Ikeda, Chris Webb, Richard E. Colbeth, Katsumi Suzuki, Saori Tanaka, Kenji Okusako

Publikováno v: SPIE Proceedings.

We developed prototype Digital Subtraction Angiography (DSA) System with a new large area FPD.Dynamic range, MTF, Contrast ratio and line noise were much improved. The improved FPD is a scintillator-type detector, and has a 40 x 30 cm active area, 20
