| Outline of Final Research Achievements |
The purpose of this study was to compare the reliability in medical use of radiographic image interpretation using medical-grade liquid crystal displays (LCDs) and general-grade LCDs (including the Tablet personal computer (PC)) by examining the observers’ performance and physical performance evaluation. When evaluating and comparing the performance of monitors, adopting luminance, contrast, modulation transfer function (MTF), and noise power spectrum (NPS) between medical-grade LCD and tablet PCs, the tablet PCs performance was equivalent to that of the medical-grade LCD. Observer performance for detecting cerebral infarction of brain computed tomography (CT) was higher on the medical-grade LCD than Tablet PC. Therefore, the Tablet PC could not substitute for medical-grade LCD monitor. However, as tablet PC has promising potentials such as portability, further examination is needed for the clinical situation using tablet PC.
