1.	Concerning the digital radio graphic image: a. It is represented numerically in digital form b. The image is divided into a matrix consisting of multiple pixels c. The greater the sampling frequency, the greater the spatial resolution d. Decreasing the detector sampling frequency may reduce detector sensitivity e. The image may be read out directly from the detector electronically
Answer» a. True. b. True. A pixel has an assigned value, which represents the signal intensity within the corresponding part of the image. The matrix size refers to the total number of pixels. c. True. d. False. Increasing the detector sampling frequency will reduce sensitivity. This is due to a decrease in the relative proportion of the pixel that is sensitive to image detection (known as the ‘fill factor’). e. True. In solid-state designs of detector, the micro-circuitry may be integrated with the X-ray absorption layer.
