In medical imagery, accurate color and precise detail are crucial and can yield critical information in grayscale CT scans and other types of radiology
Canon REALiS SX80 Mark II D Among the many institutions scrutinizing such images on a regular basis is the University of North Carolina School of Medicine’s Department of Radiation Oncology. It recently When upgraded its video-display capabilities two REALiS SX80 Mark II D Multimedia LCOS Projectors from Canon U.S.A.
“The medical requirements for a good projector are that it provides very accurate color representation, stable images, readable small print, and very quiet operation,” said Dr. Julian Rosenman, of the Department of Radiation Oncology. “On all of these aspects, we have been very pleased with the Canon REALiS SX80 Mark II D.
“We do a lot of tumor boards and telemedicine meetings in which doctors view medical images to make treatment decisions. These images can range from color histology slides, to black-and-white CT scans displaying critical shades of gray, to everything in between. This is why the color accuracy of projected images is so important,” he said.
Using two ceiling-mounted Canon SX80s, doctors and medical students display multiple sets of image data for dual-projection image comparison and analysis.
The two projectors are also used for telemedicine as images displayed by the projectors and pictures of the doctors are captured by a video conferencing camera for live consultation with other medical professionals in distant locations.
“Dual projection is a ‘must’ for patient review and for telemedicine,” Rosenman said. “Two different kinds of data are projected to confirm that they are compatible and correct with respect to each other. Image stability is also very important when you are comparing medical data. I don’t know how Canon does it, but the REALiS SX80 Mark II D Projectors reject the jitter and 60-cycle interference caused by the other electrical equipment we’ve got going. With these REALiS projectors you don’t see rolling bars or visible beat frequencies.”
The DICOM Simulation Mode on the SX80 simulates the results of a DICOM (Digital Imaging and Communications in Medicine) Part 14 compliant device, which is a standardized display function for display of grayscale images. Canon’s DICOM Simulation Mode allows users to calibrate directly on the projector using 21 different levels of grayscale gradation.
