Question

Tube arcing might cause _____ on the images.

1) star-like artifacts at the edges
2) an increased appearance of noise
3) shading and inaccurate CT numbers
4) an appear of a circle or ring

Answer 1

Tube arcing in imaging equipment can lead to shading and inaccurate CT numbers due to disturbances in the path of charged particles, such as electrons, which create inconsistencies in captured images.

Step-by-step explanation:

Tube arcing in the context of imaging technology, such as CT scans, can lead to specific types of image artifacts. When the electrons in a tube, such as a CT scanner's X-ray tube, are subjected to disturbances like arcing, they may move in tight circles or be deflected in various ways. This results in a distortion of the image captured by the equipment.

Based on the given information, tube arcing might cause shading and inaccurate CT numbers on the images, since the path alteration of charged particles within the tube can lead to inconsistencies in the image density and CT quantity accuracy.
