Abstract

A Selenium thin film transistor (STFT) array-based rotational volume tomographic digital angiography (VTDA) imaging system has been constructed. The system consists of an x-ray tube and a STFT detector that are separately mounted on a gantry. This system uses the STFT array as a two-dimensional (2D) detector so that a set of 2D projections can be acquired for a direct three-dimensional (3D) reconstruction. This paper presents the results of the preliminary phantom studies using the STFT- based volume tomographic angiography imaging system. This research work demonstrates through phantom studies that the STFT array introduces no distortion and the STFT-based VTDA imaging system has a higher spatial resolution and better contrast resolution than an image intensifier(II)-based system.
