Devices to control scatter

cones/cylinders, aperture diaphragms, collimators, filters, grids, lead blockers

Effects of increased collimation

decreased exposure, density, scatter, FOV, # of photons striking the IR, increased contrast, visibility of detail

emitted isotropically from patient, 10-90% of film density, affects density, contrast and visibility of detail
