New digital detectors were developed for medical applications, which have the potential to substitute the X-ray film. Digital Detector Arrays (DDA: Flat Panel Detectors, Line Detectors) and Imaging Plates (Computed Radiography, CR) allow a fast acquisition of radiographic images with higher dynamic than film. Especially DDA’s allow a radiographic inspection with considerable higher image qualit...

Rice algorithm, which has been recommended by Consultative Committee for Space Data System (CCSDS) for space telescope image lossless compression, is studied. Due to the similarity, this algorithm is applied on lossless compression of X-ray digital image after improvement and a satisfying compression rate is obtained. Firstly, the algorithm process is presented. Later on, the compression and de...

An accurate morphological assessment of blood vessels and their relationship with interventional devices is essential in the management of vascular lesions, and digital subtraction angiography (DSA) has had a central role in the deployment of interventional procedures. The introduction of three-dimensional rotational angiography (3D RA) and flat panel detector technology has further contributed...

Real time imaging in the field of industrial radiography arrived over half a century ago and even before that in medical radiography. All the progress in the field for first 30 – 35 years produced analog images. Digital images have come only recently. Fluorescent screens, proximity focus intensifier and then electromagnetically focused Image Intensifier produced real time images in analog. They...

We designed 4x4 matrix TFTs arrays using current mirror amplifiers. Advantages of current mirror amplifiers are they need less requiring switches and the conversion time is short. The TFTs arrays 4x4 matrix using current mirror circuits have been fabricated and tested with success. The TFTs array directly can process signals coming from 16 pixels in the same node. This enables us to make the su...
