Canon Inc exhibited a short-focus projector that can project medical images (DICOM images) taken by an X-ray CT scanner, etc at a trade show in Japan.

The projector was showcased at International Modern Hospital Show 2014, which runs from July 16 to 18, 2014, in Tokyo. It is the industry's first short-focus projector that supports DICOM (digital imaging and communications in medicine) images, Canon said.

"It is suited for use at conferences in hospitals, and we are receiving inquiries especially from university hospitals," the company said.

Because the projector incorporates the image characteristics of DICOM (gamma curve characteristics), it can project DICOM images without lowering their resolutions. For example, at a conference to examine cases in a hospital, presenters do not have to say, "This part of the image is unclear because this is a projected image."

The projector supports full-HD resolution (2,000 x 1,000 pixels). The brightness and size of an image projected by it are 4,000lm and 100 inches from a distance of 1.2m and 200 inches from a distance of 2.4m. Because it uses an LCOS (liquid crystal on silicon) LCD panel as a display device, it can realize smooth images without lattice patterns.
