Question 1

Offset correction is used to remove inherent signal that remains in a detector.

Accepted Answer

Offset correction is a process that is used to remove a baseline or inherent signal from a detector, which can interfere with the accurate measurement of the desired signal.

Question 2

Gain calibration will remove inherent detector artifacts from an image.

Accepted Answer

Gain calibration is a technique used to remove inherent detector artifacts from an image, such as variations in sensitivity across different areas of the detector. By correcting for these artifacts, the resulting image will be more accurate and reliable.

Question 3

All flat-panel detector systems have the ability to take images faster than the detector can accommodate.

Accepted Answer

Flat-panel detector systems are designed to capture images at the maximum speed the detector can accommodate, not faster. The speed of image capture is limited by the detector's readout speed and processing capabilities.

Question 4

The absorption material can be attached to the pixel array electrically or physically.

Accepted Answer

The absorption material can be attached either electrically, by integrating it with the pixel circuitry, or physically, by depositing it on top of the pixel array.

Question 5

The 2-D array determines whether the imager is direct conversion or indirect conversion.

Accepted Answer

The distinction between direct and indirect conversion in imaging systems (such as digital X-ray imaging) is determined by how X-ray photons are converted to electrical signals, not by the dimensionality of the array. Direct conversion converts X-ray photons directly into electrical signals, while indirect conversion first converts X-rays into visible light, which is then converted into electrical signals.
