Benefits of technology
The patent describes a medical imaging system that can display multiple video signals on one screen. The system has a processor that receives a video signal and generates multiple portions of the video signal. The processor then alternately updates each portion with different parts of the video signal to create an updated signal. The system can display the updated signals in different areas of the screen or on a single monitor. The system can also combine the signals for display in a picture-in-picture display. The technical effect of this invention is that it allows for more efficient and effective display of multiple video signals on a single screen, making it easier for medical professionals to view and analyze the images.
Problems solved by technology
A difficulty with the use of a white light or wide band light source is that hemoglobin absorbs the majority of optical light, and the penetration depth of light is closely related to the absorption spectrum of hemoglobin.
Due to the short penetration depth of blue light (˜1 mm), intermediate penetration depth of green light (˜3 mm) and high penetration depth of red light (˜5 mm), the tissue structures near the surface are easily identified, but information in the red spectral region cannot be easily obtained due to the high penetration depth.

Embodiment Construction
[0039]FIG. 1A shows a medical imaging system having an image capture device or camera, such as an endoscope 2. A light source 22 illuminates the body cavity where the endoscope 2 is inserted. The light source 22 will typically be a broad band or white light source. The endoscope 2 produces a video signal 20, and the video signal has a plurality of portions etc. The video signal may come to the processor already divided into the plurality of portions. Alternately, the processor 4 can divide the video signal into the portions for processing and display. The processor 4 can exist on a camera control unit or other imaging system. The video signal 20 is processed according to a pattern where different portions of the video signal 20 are processed according to one or more signal processing modes, for example the video signal may be processed according to different bandwidth selections. The selections 60 are received by the processor. These selections 60 can indicate, for example, differen...

A medical imaging system having a processor with software executing thereon is provided for processing and display of multiple bandwidths of video in multiple display areas. The system receives a video signal with a plurality of portions and generates at least two signals there from. Each of the two signals has a bandwidth for display in a different display area. The two signals are updated so that each component displays a different portion of the input video signal, and the two signals may be combined for display on a single display device having two display areas.
Description
FIELD OF THE INVENTION[0001]The invention relates to image capture, processing and display devices, and more particularly medical imaging and devices.BACKGROUND OF THE INVENTION[0002]During medical procedures, endoscopes and other imaging devices are used to perform minimally invasive surgery and diagnostics. These imaging devices typically use a broad band light source to illuminate the tissue inside a cavity so that an image sensor can capture the reflected light and send a signal to a processor for display.[0003]A difficulty with the use of a white light or wide band light source is that hemoglobin absorbs the majority of optical light, and the penetration depth of light is closely related to the absorption spectrum of hemoglobin. In the visible spectrum, hemoglobin shows the highest absorption of blue (˜410-440 nm) and green (˜530-580 nm) wavelength regions. Therefore, optical information obtained in the blue and green spectral region can discriminate hemoglobin concentration an...
