Abstract

A medical examination system includes components for generating an internal image of a patient, such as an x-ray image, and components for generating an image of the external surface of at least a portion of the patient. The signals obtained from the surface scan of the patient are used to control the positioning of other components, such as the patient support and/or the primary radiation diaphragm. The internal and surface images can be compared to achieve precise positioning of the patient and/or a setting of the primary radiation diaphragm to avoid blooming.
