Abstract

|
Whole-body bone scan (WBBS) is one of the most frequent diagnostic procedures in nuclear medicine. Especially, it plays a significant role in important procedures such as the diagnosis of osseous metastasis and evaluation of osseous tumor response to chemotherapy and radiation therapy. Also, Most patients with bone metastases regularly receive bone scans. In this paper, we presents the method of image enhancement which may assist radiologists in interpreting successive whole-body bone scans effectively. The method makes the size, orientation and intensity of objects consistent for effective comparison and analysis. The first processing is the normalization of size and orientation based on the object detected in WBBS. And the second one is the enhancement of intensity based on histogram. Consequently, it can improve radiologists’ diagnostic accuracy as well as reduce reading time for detecting interval changes.
