| Research Abstract |
We developed the realtime tumor tracking algorithm based on the human numeric phantom with intrafractional organ motions. Since real human organ motion is much complex, we improved our algorithm by using several data sets reflected to clinical situation. While radiation exposure to the patient is another major problem in X-ray fluoroscopic imaging because A relative large magnitude of radiation exposure may be necessary to improve tumor tracking calculation accuracy. To overcome this problem, we developed the image processing algorithm to improve quality of fluoroscopic image, as a result, this technique could reduce the magnitude of radiation exposure with prevent the accuracy of tumor tracking.
