Image processing system for medical diagnosis - has zoom facility to locate and display area with improved definition

摘要

An image processing system for use in medical diagnostic applications has a zoom facility for locating a specific area in greater detail. The input image (21) is received by a zoom processor (24) under the control of a keyboard (22) that allows the area of interest to be selected and the zoom factor to be entered. The zoom processor has the function of determining intensity values for the region. The processor also used reference values that are held in table form within a core function memory (27). The values are used within an interpolation process used in the graphical zoom operation. ADVANTAGE - Provides improved image in zoom process.
