“…Any tiny pinholes or inhomogeneities in the a -Se material can contribute to a breakdown and immediate destruction of the underlying TFT transistor, plus it can damage much of the other electronic circuits. To avoid this and also to decrease the dark current, Sterling Diagnostic Imaging developed a special (patented) structure consisting of a thick insulator layer between the a -Se layer and the bias electrode [3] . An additional charge blocking layer was applied between the a -Se and the TFT array, which further decreased the dark current.…”

“…The definitions of MTF and CTF do not include the concept of noise. Since noise is always present in an image, DQE (or NEQ) therefore give a better indication of the overall image sharpness and image quality [18,19,20].…”

“…Photo carriers are generated in the semiconductor layer of the MIS-type photoelectric converter by absorbed visible light, and accumulated in the MIS capacitor. The accumulated carriers are read out by switching the TFT [18,19]. The conversion from analog to digital information takes place with a 14-bit resolution.…”

Digital chest radiography with a large-area flat-panel silicon X-ray detector: clinical comparison with conventional radiography

et al. 2001

This was a radiologists' preference study to compare a digital chest radiography system that utilizes a large-area silicon flat-panel detector with conventional radiography for visualizing anatomic regions of the chest. Conventional and digital posteroanterior (PA) and lateral chest radiographs were obtained in 115 patients. The PA and lateral image pairs were compared independently by three radiologists rating the overall appearance, 11 anatomic regions in the PA, and 9 in the lateral views. Statistical analysis was performed with the Wilcoxon signed-rank test with Bonferroni-Holm adjustment (p=0.05). For the PA view, the digital system performed significantly better for the overall appearance and for all anatomic regions except for the peripheral pulmonary vasculature and hilum, where no significant difference was found. For the lateral digital images, the regions trachea, costodiaphragmatic recess, and hilum were rated significantly worse. The regions retrosternal and retrocardiac lung were rated significantly better. The other regions and the overall appearance showed no significant differences. The described digital chest radiography system showed statistically superior visualization of anatomic regions for PA and an ambiguous performance for lateral images as compared with conventional radiography. After changing some image processing parameters for the lateral view, this system may be suitable for digitalization of chest radiography.

-This paper presents the implementation of a laboratory classroom simulation of radiology networking technology. The simulation focuses on educating undergraduate students in various aspects of installing and applying radiology Picture Archiving and Communication Systems (PACS) in a networked environment, based on the Digital Image and Communication in Medicine (DICOM) standard, with particular emphasis placed on studentcentered learning. Laboratory structure enables students to simulate the operation of radiology departments in terms of DICOM communication with imaging devices, storage and archiving of DICOM information and DICOMcompatible digitization of film-printed radiographs.
