Gamma camera collimators

Question

Quizplus · Accepted Answer

Gamma camera collimators function much like radiographic grids in their selectivity, as they only allow certain photons to pass through and reach the detector, while others are absorbed. Option A is incorrect as x-ray beam collimators are used in x-ray imaging and not in gamma imaging. Option B is incorrect as gamma camera collimators have multiple holes, not thousands, and the length-to-diameter ratio depends on the type of collimator. Option D is also incorrect as different collimators are used for specific imaging purposes.
