What typically happens to the dose with greater magnification in fluoroscopy?

When magnification is used in fluoroscopy, the dose to the patient typically increases. This happens because magnification requires an increase in the amount of radiation to maintain image quality. When the area of interest is magnified, the x-ray tube needs to produce a more concentrated beam of radiation to ensure that the details of the image are clear and visible.

This increase in radiation dose occurs because the system has to compensate for the reduced amount of incoming radiation that reaches the image receptor due to the magnification factor. The resulting higher dose can lead to increased exposure for the patient, making it important for clinicians to balance the need for detailed imaging with the associated risks of higher radiation exposure.
