Energy subtraction in digital fluoroscopy exhibits less of which than temporal subtraction?

Energy subtraction in digital fluoroscopy is designed to minimize certain types of noise and interference in the image acquisition process. One key aspect of this technique is that it effectively reduces motion artifacts, which arise from patient movement during the imaging process. Motion artifacts can obscure the clarity and accuracy of the images, leading to difficulties in diagnosis.

In energy subtraction, the images are created by distinguishing between different energy levels of X-rays by utilizing specific energy windows to enhance contrast. This allows for the separation of the signal from the noise generated by different tissue types or substances, improving the resultant image quality.

In comparison to temporal subtraction, which relies on taking sequential images over time and can have challenges with motion, energy subtraction specifically targets and mitigates those motion-related effects more effectively. Thus, energy subtraction is associated with a decrease in motion artifacts, making it a preferable method in situations where patient mobility may introduce blurring or distortion in the images.
