Q.22.The power and energy used to make medical images require a balance between patient safety and ______ quality.

A. data quality

B. image quality

C. contrast quality

D. none of the above

Explanation 

The medical image can have an aesthetic appearance, the diagnostic utility of a medical image relates both to the technical quality of the image and the conditions of its acquisition. Consequently, the assessment of image quality in medical imaging involves very little artistic appraisal and a great deal of technical evaluation; like, in most cases, the image quality that is obtained from medical imaging devices involves compromise- better x-ray images can be made when the radiation dose to the patient is high but patient safety and comfort must be considered when acquiring medical images. So, excessive patient dose in the pursuit of a perfect image is not acceptable. Therefore, the power and energy used to make medical images require a balance between patient safety and image quality.
