Diagnostic Monitor vs Clinical Review Monitor
🆎 Quick Comparison
| Feature | Diagnostic Monitor | Clinical Review Monitor |
|---|---|---|
| Intended Use | Primary image interpretation and reporting; legally approved for diagnosis. | Secondary review / consultation; not for formal diagnosis. |
| Regulatory Approval | Certified to medical standards (e.g., FDA 510(k), CE, TGA, MQSA). | Typically not certified for diagnostic use. |
|
Calibrated Brightness (Brightness after DICOM calibration) |
≥350 cd/m². ≥420 cd/m² for mammography. | Lower, 200–300 cd/m² calibrated typical. |
|
Maximum Brightness (Brightness before DICOM calibration) |
Typically ≥450 cd/m². | Typically ≤450 cd/m². |
| Resolution / Pixel Count | ≥6MP general (≥3MP for Vertical); ≥12MP for mammography(≥5MP for Vertical). | Often 2MP; sufficient for review but not subtle findings. |
| Grayscale Accuracy (DICOM GSDF) | Strict DICOM calibration with regular constancy tests, tighter QA tolerance (± 10%). | May have a DICOM preset; looser QA tolerance (± 20%). |
| Contrast Ratio | 1000:1 or higher, optimized for diagnostic grayscale. | Lower (500:1–1000:1). |
| Uniformity Correction | Hardware luminance/color uniformity correction meeting tight tolerances. | Partial/basic correction; not guaranteed to diagnostic specs. |
| Calibration Tools | Build-in front sensor, plus self-developed QA software with hardware calibration. | External sensor may be needed; basic OSD or optional tools; often lacks automated QA reporting. |
| Bit Depth / LUT | 10bit; high-precision LUT (14–16-bit) for smooth gradients. | Usually 8-bit; higher chance of banding. |
| Ambient Light Control | Strict reading-room standards; warning if too bright; anti-glare/reflection coating. | More tolerant; depends on general office/clinical lighting. |
| Ergonomics & Size | Reading-room optimized. | General purpose, convenience oriented. |
| Cost | Higher | Lower |

❗️Core Specification
DICOM Calibration Accuracy: Clinical review monitors may permit larger tolerances (±20% from GSDF) vs diagnostic monitors which often require tighter tolerances (±10% or tighter).
Calibrated Brightness: Diagnostic (≥350 cd/m², ≥420 cd/m² for mammography), clinical review (250–300 cd/m²).
Contrast Ratio: Diagnostic (1000:1 or higher), clinical review (500:1–1000:1).
⚖️ In Short
Diagnostic monitors: legally certified, high-spec displays for radiologists.
Clinical review monitors good image quality, large screens, but not certified for primary diagnosis.
