Surgical Microscope Camera Provides Integrated 4K Capabilities

An innovative medical camera with a native 4K chip produces four times the pixels of high definition (HD) cameras for exceptional image quality.

The Med X Change (Bradenton, FL, USA) 4Klear camera and medical video recorder is an all-in-one, vendor-neutral solution for surgical microscopes based on a 1/2 ", 460 Khz, 4K complementary meta-oxide-semiconductor (CMOS) chip that delivers high-sensitivity, vivid color, and superior resolution at all magnification levels. The 4Klear CMOS also delivers a wider field of view than previous 1/3" chips, with lower noise and a higher (10bit) color depth, producing an image closer to that a surgeon sees through the microscope oculars.

Features include an integrated 12.7 cm multi-touch screen for camera and recorder controls; integrated 4K recording and still capture; multiple video outputs, including 12G-SDI, HDMI 2.0, Quad-SDI, 3G-SDI, and DP 1.2; image management workflow with physician preferences; unlimited camera scene files for each specialty; options for Digital Imaging and Communications in Medicine (DICOM) integration and live video over IP streaming (RTSP); and Medxstream Plus, an iOS App that allows the user to wirelessly control the camera and functions via an encrypted connection.

The 4Klear camera is compatible with all major microscope manufacturers, including Carl Zeiss Meditec, Leica Microsystems, Haag-Streit Surgical, Alcon, Mitaka Kohki, Takagi, Topcon, and others,” said the company in a press statement. “The state-of-the-art 1/2 ", back-illuminated 4K CMOS chip produces more light per pixel for light sensitive operations, and reduces noise in the video all designed to give the surgeon and staff critical clarity for the surgical environment.”

4K resolution refers to a horizontal resolution of 4,096 pixels. The use of width to characterize the overall resolution marks a switch from previous video standards such as 480i and 1080p, which categorize media according to its vertical dimension. Using that same convention, 4K would be named 2160p. As 4K is becoming standard, manufacturers are working on the next step, 8K, which forms an image dimension of 7,680×4,320 pixels.
