Abstract
Although many images are handled in the medical filed, image monitoring deices and filing methods vary due to differences in resolution and pixel depth. If a system enabling such images to be filed synthetically without losing its quality were to exist, and if retrieval of such images were made easily, such a system could be applied in various ways. In order to determine whether a super high definition (SHD) image system running at a series of 2048 resolution X 2048 line X 60 frame/sec was capable of such purposes, we established a filing system for medical images on this system. All images of various types produced form one case of cardiovascular disease were digitized and registered into this filing system. Images consisted of plain chest x-ray, electrocardiogram, ultrasound cardiogram, cardiac scintigram, coronary angiogram, left ventriculogram and so on. All images were animated and totaled a number of 243. We prepared a graphic user interface for image retrieval based on the medical events and modalities. Twenty one cardiac specialists evaluated quality of the SHD images to be somewhat poor compared to the original pictures but sufficient for making diagnoses, and effective as a tool for teaching and case study group purposes because of its operability of the retrieval system. The system capability of simultaneously displaying several animated images was especially deemed effective in grasping comprehension of diagnosis. efficient input methods, and creating a capacity of filing all produced images are future issue.
