Abstract
This work presents volumetric color medical image compression for the Picture Archiving and Communication Systems (PACS) using AT-SPIHT algorithm. PACS has inclined the medical information system by integrating RIS, HIS and all the imaging modalities and scanning devices to PACS so that doctor's use the PACS efficiently for diagnosis and decision making in petite time. PACS has the potential usage in telemedicine applications which is the future in medical field. With the above technology, enormous digital images are generated and stored in PACS for the doctor's diagnostic purpose where volumetric color medical image compression is imperative and to utilize the PACS competently. The volumetric color medical images are a three-dimensional (3-D) image data set, and can be considered as a sequence of two- dimensional (2-D) slices. AT-SPIHT applied to the 3-D color Computed Tomography (CT) medical image is an efficient progressive coding technique. AT-SPIHT algorithm utilizes a more efficient spatial orientation tree structure. This novel technique enables the PACS implementation and deployment in medical information system.
