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.
Claims11
A medical examination system for examining a patient comprising:
- means for generating an internal image of said patient, said means including an adjustable component;
- means for scanning a surface of said patient and generating a surface image of said patient;
- a memory for storing said surface image;
- and
- means for comparing said surface image stored in said memory with a current internal image of said patient for generating a drive signal for said adjustable component based on the difference between said stored image and said current image.
A medical examination system for examining a patient comprising:
- means for generating an internal image of a patient, said means including an adjustable component;
- means for storing said internal image;
- means for comparing a stored internal image with a current internal image and for generating a first comparison result dependent upon the correlation of the stored and current internal images;
- means for scanning a surface of said patient and generating a surface image of said patient;
- means for storing said surface image of said patient;
- means for comparing a stored surface image with a current surface image and generating a second comparison result dependent upon the correlation between said stored and current surface images;
- and
- means for evaluating said first and second comparison results to generate a control signal for said adjustable component.
