Abstract: A portable X-ray film cassette holder for a wheelchair is disclosed whereby the patient can remain stationed in the wheelchair and need not be removed therefrom for X-ray photography. The cassette holder has quickly adjustable mounting means enabling the holder to be used with differently sized wheelchairs and further provides portability for expeditiously taking sequential photographs of different wheelchair-bound patients.

Abstract: Restraint apparatus is provided for immobilizing a pediatric patient during exposure of X-ray film, particularly in connection with chest examinations. The invention permits considerable reduction in the extent of exposure area of the patient's body. Manual restraint is not required and hence non-patient exposure to radiation is avoided. Because movement is restrained, the need to re-expose the patient is virtually eliminated. Adjustment is provided for the comfortable accommodation of infants up to small children. The apparatus secures both arms of an infant or small child in a forward and upward extension to achieve proper anatomical positioning for anterior-posterior or lateral chest X-ray study. Adjustable holders for different size film cassettes form part of the apparatus.

Abstract: Apparatus for immobilization of infant patients during exposure of X-ray film, particularly in connection with studies requiring the so-called frog-leg position. Use of this invention permits considerable reduction in the extent of exposure of the patient's body, and eliminates the need of manual restraint of extremities and exposure of a non-patient to radiation. Moreover, the required size of film is much reduced. In a preferred embodiment antero-posterior projections of a patient in both straight supine, and frog-leg positions are shown on a single 10 x 12 inch film. The invention virtually eliminates the need to re-expose because of movement of the patient.
