Embodiment Construction

[0048] In the text below, a "display system" is a collection of hardware (displays, display controllers, etc.), and a "display" is considered a physical display device (e.g., a display for displaying 2D content, a display for displaying 3D content, medical-grade displays, high-resolution displays, liquid crystal displays (LCDs), cathode ray tube (CRT) displays, plasma displays, etc.), a "frame buffer" is a segment of video memory used to hold images to be displayed on the display, And a "display image" is the content of the frame buffer stored in the frame buffer that will be output on the display using all or a portion of the pixels available on the display. A "virtual display image" is an image displayed without a dedicated display but with a frame buffer. A "virtual display" is an area on a display used to present a virtual display image. Also, the display image is not the same as the "desktop". A desktop is a collection of all display images including virtual display ima...

Abstract

A system is provided for generating a virtual display (21) that is displayed on an existing display (2) using a memory of a device as a frame buffer for the virtual display. The virtual display may use random access memory (RAM) or memory of the graphics processing unit (GPU) of the device (e.g. a computer) as a second frame buffer (17) to generate the frames displayed in the virtual display. The virtual display is not a physical display and, thus, does not require any additional hardware or physical space. Rather, the virtual display is displayed on the existing display. The existing display is also used to display the frames generated in a first frame buffer (16).

Description

technical field [0001] The present invention relates generally to display systems, and more particularly to methods and systems for adding virtual displays without requiring additional physical displays. Background technique [0002] In the medical field of radiology, physicians use high-end diagnostic monitors to analyze medical images and make diagnostic decisions. A typical radiology or mammography workstation includes multiple monitors and often multiple software applications that allow the radiologist to display multiple images. Radiology / mammography workstations often also include a "navigation head". The navigation head is a display that allows the user to select and show patient information and information about the image being studied. The actual medical image is first displayed on the system's other displays. [0003] Navigation headers are often used to display navigation and support non-diagnostic applications (for example, dictation software or editing softwa...
