front 1 ADC | back 1 (analog-to-digital converter) converts image information into numerical data |
front 2 AEC | back 2 automatic exposure control (ionization chamber located between the patient and the image receptor) |
front 3 Collimator | back 3 box-like structure attached to the x-ray tube containing lead shutters that limit the x-ray beam to a specific area of the body. |
front 4 Automatic collimator | back 4 also known as positive beam limitation(PBL); the ability of the radiographic equipment to collimate automatically the x-ray beam to the same size as the image receptor resting in the Bucky tray. |
front 5 Contrast resolution | back 5 the smallest change in signal that can be detected by the image receptor |
front 6 Spacial resolution | back 6 the sharpness of the structural edges in the radiographic image; the smallest detail that can be detected |
front 7 Exposure indicator | back 7 describes the status of the exposure and diagnostic value of the digital imag |
front 8 Image receptor | back 8 any device or medium that captures the remnant beam |
front 9 Image plate | back 9 plate that is coated with photostimulable phosphors that absorb the photon energies exiting the patient; located inside a computed radiography (CR) cassette |
front 10 Voluntary motion is caused by the following: | back 10 • Nervousness |
front 11 Involuntary motion is caused by the following: | back 11 • Heart pulsation |
