Abstract :
A method has been developed using which the foreground (body) in a fluoroscopy image of the peripherals can be segmented from the background (existing collimation and direct exposure). The extracted information about where the body is in an image is used to suggest settings for the collimator hardware during image acquisition. Segmentation is achieved through global feature extraction and supervised classification
