[์˜๋ฌธ]Digital Imaging and Communications in Medicine (DICOM) is the standard among the digital medical imaging systems. DICOM toolkit is the software to implement DICOM. It is essential to develop any digital medical imaging systems. Commonly accepted toolkits have following obstacles. 1)Since they only support functions for DICOM, developers have to implement the image processing and display related functions by themselves. Some toolkits provide those funtions, but they are not suitable for medical images. 2) Since toolkits are designed and implemented at UNIX, when it is used hospitals which are using the Windows for their PACS, the ported code can not play the best performances. 3) The processing time of the conventional toolkits are slow and the memory requirement is too high. So it is not adequate for the hospital environment that handles mass image data. 4) Since toolkit structure is too complicated, which are mainly due to the complexity of DICOM, we need to develop highly efficient structure for DICOM. In this paper, the developed toolkit has solved the problems in the conventional DICOM toolkits and has following features. 1) It provides not only DICOM and image related functions but also supports medical image specialized functions. 2) It is designed to do best performances at Microsoft Windows which is currently becoming major operating system in hospital computer environment. 3) It guarantees high image processing and display speed and uses less physical memory. 4) It is designed as object oriented structure for the simplification of the structure of DICOM complexity and supports most of functions needed at PACS environment. The developed toolkit took 12 seconds to display 120 images which are collected from different modalities and manufacturers. And the developed DICOM used less physical memory space than others. And the developed DICOM has been successfully applied for the following image modalities such as PACS viewing system, Digital Fluoroscopy, Console of Computed Tomography and the Digital Slit Lamp system.ope
