Resolution in fluoroscopy is measured in which unit?

Resolution in fluoroscopy refers to the ability to distinguish between different structures in the imaging process. It is quantified using line pairs per millimeter (lp/mm), which indicates how many pairs of black and white lines can be effectively distinguished within a millimeter of the image. This unit is pertinent because it directly correlates to the sharpness and clarity of the obtained images, which is essential for accurate diagnosis and evaluation.

Other units listed, such as cubic centimeters (cc), pounds per square inch (psi), and kiloelectronvolts (keV), do not pertain to resolution. Cubic centimeters measure volume, psi is a unit of pressure, and kiloelectronvolts pertain to energy levels associated with the radiation used in imaging. Therefore, they are not relevant to the assessment of image resolution in fluoroscopy. Understanding that resolution is specifically expressed in lp/mm helps strengthen the knowledge of imaging quality in medical contexts.
