Step 1. Understand the basics of digital radiography
{"Image DocumentName": "Step 1. Understand the basics of digital radiography", "Image ImageDescription": "Direct Digital Radiography (DR) Readout process. Thin-film transistor layer bonded with image receptor. Readout availability in less than 10 seconds. Image Receptors. Two types depending on method of converting x-ray to image. 1. Direct converts x-rays to electrical charge. Selenium most common type of receptor. 2. Indirect converts x-rays to light which then produces electrical charge. CsI and Gadolinium Oxysulfide most common types. DR uses x-ray sensors bonded onto thin-film transistor integrated circuits to instantaneously convert the image stored on the sensor to a visible digital image, eliminating the need for a separate scanning step. DR can use either direct detection (converting x-rays into electronic charge) or indirect detection (first converting x-rays into light, which is then converted to electronic charge), resulting in readouts that are much faster (typically less than 10 seconds) than CR. Selenium is the most common type direct conversion DR. CsI and Gadolinium Oxysulfide are the most common types of indirect conversion DR.
