Abstract
Liquid-crystal displays (LCDs) used for medical imaging, such as luminance characteristics and panel surface processing, have been developed as a medium substituting for film. There are various models of and specifications for display, but those compatible with high-resolution radiographic diagnostic images have been required with the recent progression of high-resolution modalities. Displays are necessary for faithful presentation of radiographic diagnostic images acquired by X-ray systems. In independent sub-pixel driving (ISD) technology, aiming at high-resolution display, three sub-pixels contained in one pixel of the LCD independently display images, which increases the threefold resolutions in direction of the sub-pixels, facilitating faithful image display with less curtailed pixels. This is a new display technology which may improve the diagnostic performance with regard to reading of medical images. We evaluated the characteristics of ISD technology and performed a visual evaluation of phantom images to investigate its usefulness. After confirming the physical properties of LCDs, we performed a visual evaluation of CDMAM phantom images employing the calculated image quality figure (IQF). The detectability of 15 mega-sub-pixel (15MsP) significantly improved despite the specification being 5 mega-pixel (5MP), and that of 9MsP was higher than that of 5MP despite the specification being 3MP. The usefulness of ISD for 6MsP was also confirmed. Therefore, ISD technology was useful for all LCDs. ISD technology markedly advanced the LCD display performance for medical use.
