Abstract
An automatic ROI tracking system for the application of ROI fluoroscopy is designed. The methods for processing in real-time, generating binary masks, equalization of the display and the scheme for the image analysis to track ROI size are described. The initial results of the system tested on a torso phantom are reported and discussed. The system results in the appearance of an almost completely equalized real-time image and the method can be incorporated into x-ray fluoroscopy units with minimum modification. With the technology, ROI fluoroscopy can be applied to interventional or diagnostic procedures for practical patient dose reduction.
