摘要：

An automatic ROI tracking system for the application of ROI fluoroscopy is designed. The methods for processing in realtime, 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.
