ABSTRACT:
The apparatus enables the taking of multiple X-ray photographs of the legs and pelvis of a patient. A platform is rotatably mounted on a base member, and is provided with means for keeping the patient still in a standardized standing position. With only minor vertical and horizontal adjustment of an associated substantially point source of X-rays, side and front X-rays can be taken without movement of the patient, apart from rotation of the platform. Radio opaque marker means provided on otherwise radio-transparent spaced screens produce, on the X-ray film, images which can be interpreted to provide information for compensation of distortions in images on the X-ray film due to the use of a point source of radiation.
