Medical Diagnostic Imaging Systems
Gigabit Ethernet (GigE) is a natural choice for video transmission within diagnostic imaging systems, due to its long-distance reach, networking capabilities, and ability to support a range of computing platforms. Many medical systems output images over a Camera Link® or LVDS connection. These interfaces suffer from bulky cables and connectors and short maximum cable distances – serious issues when images need to be transmitted through an umbilical connection.
In the diagram below, the x-ray detector sends images over existing Camera Link or LVDS interfaces to one of Pleora’s iPORT™ PT1000-CL or PT1000-LV External Frame Grabbers, where the images are converted to GigE. Images from a Sony block camera in the operating room lamp head are converted into a GigE Vision-compliant video stream by the iPORT SB-GigE External Frame Grabber. Due to Ethernet’s long cable reach, system designers can move the processing and display computers away from the x-ray system and place them elsewhere in the operating or examination room, or even down the hall.
At the PC, all the interfaces connect via GigE, eliminating the need for a computing platform with an available peripheral card slot. As a result, system designers can reduce system size, cost, and power consumption by using computing platforms with smaller form factors, such as laptops, embedded PCs, and single board computers. Pleora’s external frame grabbers are a natural alternative to traditional PCI frame grabbers or medical display boards.
To enhance reliability, Pleora’s external frame grabbers can be set to multicast image data to multiple computing platforms simultaneously, using an off-the-shelf GigE switch. In this example, images are being sent to a PC performing display and control functions, and to a vDisplay™ HDI-Pro External Frame Grabber, which is being used solely for display.
