Non-subtraction type of digital imaging is used to:

1. avoid misregistration artifacts in subtracted images
2. reduce patient motion
3. maintain contrst levels
4. improve resolution

Answer 1

Non-subtraction digital imaging is used to avoid misregistration artifacts in subtracted images, reduce patient motion, maintain contrast levels, and improve resolution.

Step-by-step explanation:

The non-subtraction type of digital imaging is used to:

1. Avoid misregistration artifacts in subtracted images: Misregistration artifacts occur when there is misalignment between images taken at different times, leading to inaccurate interpretation. Non-subtraction imaging eliminates this issue by capturing images without the need for subtraction.
2. Reduce patient motion: Digital imaging techniques like computed tomography (CT) or magnetic resonance imaging (MRI) require the patient to remain still for accurate image acquisition. Non-subtraction imaging helps minimize patient motion, leading to clearer and more precise images.
3. Maintain contrast levels: Contrast is crucial in medical imaging as it helps distinguish between different tissues and structures. Non-subtraction imaging techniques ensure that the contrast levels remain optimal, enabling better visualization and interpretation of the images.
4. Improve resolution: Non-subtraction imaging techniques can improve the resolution of the captured images, allowing for more detailed examination and detection of abnormalities.
