Detailed explanation of key technical indicators

Brightness uniformity requirements

The standard adopts the nine-point measurement method (screen size ≥23 inches), and the calculation formula is: Lu=100-200×(Lhighest-Llowest)/(Lhighest+Llowest). The breast diagnosis display requires ≥85%, which is 10 percentage points higher than the ordinary type.

TG18-OIQ Test Specification

Contains 8 visual inspection items, with special requirements: Breast Diagnosis Display must fully display the letters "QUALITYCONTROL" in the black area, while the ordinary type is allowed to lack the last 3 letters.

Clinical Application Recommendations

Equipment Selection Guide

1. Radiology CT/MRI diagnosis should choose ordinary diagnostic monitors, which can meet the brightness of 350cd/m²
2. Mammography examination must be equipped with a dedicated breast diagnostic monitor, ensuring a high brightness of 450cd/m²
3. PACS reading workstations are recommended to have dual screens, with the main screen resolution not less than 2048×2560

Key Points for Implementation of Standards

1. A color analyzer should be used for grayscale chromaticity detection every quarter (Δu'v'≤0.01)
2. When detecting brightness response error, the tolerance of the breast monitor is only 5%, and professional calibration equipment is required
3. The grid test requires that the display area edge integrity error is less than 1%
