Image viewing station for picture archiving and communications systems (PACS)
First Claim
1. An image viewing system comprising:
- first memory for storing raw image data corresponding to plural images to be displayed;
image processing means coupled to said memory means for performing predetermined processing operations on said raw image data and for providing corresponding display data, said image processing means including,zoom means responsive to said stored raw image data for obtaining values of estimated image data at points along a line between said data by a fractional bilinear interpolating between the values of said raw image data to produce selectably continuous magnification or minification of the image;
second memory means coupled to said image processing means for storing the display data processed by said image processing means;
user input means for generating input signals indicative of selected images and image formats to be viewed;
display means coupled to said second memory means for displaying images based on the display signals stored in said second memory means; and
control processing means connected through an internal bus to said first memory means, image processing means, and second memory means for producing control signals responsive to said input signals from said user input means for controlling transfer of raw image data corresponding to selected images to be displayed from the first memory means to the image processing means, processing thereof by said image processing means, storage of the processed display signals into the second memory means, and transfer of the stored display signals to said display means for display of the user selected image.

Abstract
An image reviewing station for a picture archiving and communication system (PACS), having two functions of user interface and display of an image wherein base memory, image processor, and display memory architecture is used. The digitized image data at any size from any different modalities is stored in base memory in an original format, and read-out signals are processed appropriately in the image processor responsive to the command signals input by the user. The processed image data is then stored in a display memory before being supplied to a display via a digital-to-analog converter for the display. It provides the user with extensive, concise and easy interactive image manipulation and processing capabilities.
