JVCKENWOOD has pioneered several technologies that have advanced the way we view
Radiology images. We strive to deliver the highest levels of performance and
that medical imaging demands.
Driven each sub-pixel value corresponding to detailed information recorded in an original image, three times resolution enhancement is achieved. (Patented)
Special AR Coating technology addresses properties of focus, noise reduction, contrast, and viewing angle achieving film-like black and accurate reproduction of images. In this paper, we describe its features and physical measurement results. (Patent pending)
Built-in LUT (Look-up Table) to reproduce beautiful grayscale and JVCKENWOOD's technology for simultaneous display of multiple shades
General-purpose displays are capable of 256 shades of gray, but due to unevenness and grayscale discontinuity, they cannot reproduce and display the subtle shading difference required for medical image displays. Our medical image displays display the most appropriate 256 shades (8 bits) out of a maximum of 3826 shades of gray (11.9 bits) using the built-in LUT. This technology realizes much finer and smoother grayscale than possible with general-purpose displays.
Medical image displays are commonly required to display grayscale according to the Grayscale Standard Display Function (GSDF) defined by DICOM Part 14. The calibration function creates the optimum conditions for a medical imaging display by adjusting luminance levels, color temperature, and grayscale characteristics to achieve DICOM GSDF compliant grayscale output.
A change in luminance affects gamma characteristics and therefore has adverse effects on diagnostic imaging. Our medical image displays are equipped with a luminance stabilizing system that automatically compensates for luminance changes due to startup drift, temperature change, and aging.
Conformance testing to DICOM GSDF and calibration can be remotely accomplished. These features minimize the burden on display administrators.
Medical imaging often uses two displays side-by-side, and it is very important that they present the same color tone.
The pivot function allows for a 90-degree rotation of the LCD panel into portrait orientation. Unlike other pivoting functions that are implemented using graphics cards and/or that require special software, JVCKENWOOD's hardware pivot function is directly implemented in display hardware and thus it is much faster with less noise.
A glance at the LED indicator tells you the display's current operating status in three distinct colors. When in normal mode (luminance is stabilized), the LED is not lighted to minimize negatively impacting the diagnostic interpretation.
