Radiographic elements useful for therapy imaging are disclosed each comprised of a film support having first and second major surfaces and capable of transmitting radiation to which the radiographic element is responsive and, coated on both of the major surfaces, processing solution permeable hydrophilic colloid layers which are fully forehardened and limited to less than 45 mg/dm.sup.2 of hydrophilic colloid to facilitate processing in less than 45 seconds, at least one of said layers on each major surface including light-sensitive silver halide grains capable of providing a contrast in the range of from 4 to 8 and containing less than 3 mole percent iodide, based on silver, the hydrophilic colloid layers allowing at least 30 percent crossover within a spectral region within which the silver halide grains are light-sensitive. The radiographic elements are useful for either in localization or verification imaging.

Portal radiographic imaging

A radiographic imaging combination that is capable of detecting soft tissue anomalies is described. This combination is particularly effective for neonatal radiography and comprises a source of X-radiation exhibiting a peak emission in the range of from 40 to 60 keV with a 2 mm aluminum equivalent filtration, a filter for the source which comprises tellurium and/or antimony, at least one X-radiation imaging screen.
