Actual assessment of the modulation transfer function (MTF) of a physical system requires objective experimental data to be obtained. This paper presents four practical methods for measuring the MTF of a linear x-ray detector. These methods are based

Solid state x-ray detectors produce high resolution medical images when scanning the patient with a narrow x-ray beam. The x-ray detection is achieved by a silicon photodiode array coated by a scintillating material. Signal is multiplexed and convert

Two years ago, a gamma camera detector, consisting of a 34 cm input field image intensifier coupled to a scintillator crystal at the input and to a silicon localizer at the output, was built and tested at Thomson-CSF. Snce that time the 34-cm model h

The artificial-looking regular conical perforations in many of the slaty pebbles found on the Marquesado del Cenete plain in Granada, Spain, are attributed to the particular nature (foliated) of the rock and local climatic conditions.

Publisher Summary A position-sensing detector employing continuous resistive electrodes as charge dividers have been extensively described in the past. A few years ago, two-dimensional position localizers were incorporated in electronic tubes for the

Linear solid state X-ray detectors are used to produce digital images. The detectors produce the X-ray image line by line as the patient is scanned with a narrow X-ray beam. One of the decisive advantages of this principle of imaging is that it rejec
