Medical Display is a professional display device designed specifically for medical imaging, diagnosis, surgical navigation, and other scenarios. It has characteristics such as high resolution, high grayscale, high brightness, color accuracy, and stability, and is a key component of modern medical imaging systems. It is widely used in radiology, pathology, operating rooms, endoscopic systems, ultrasound, clinical PACS systems, etc.
1, The difference between medical screens and ordinary displays
Display accuracy: The medical screen supports high grayscale display (above 1000 levels), with clearer image details; Ordinary monitors typically have only 256 levels of grayscale, resulting in poor detail performance.
Brightness and Contrast: Medical screens have high brightness and strong contrast, making them suitable for reading videos; Ordinary monitors have lower brightness and are prone to losing details.
DICOM calibration: The medical screen supports the DICOM standard to ensure consistent brightness of medical images; Ordinary displays are not supported and cannot be used for diagnosis.
Long term stability: The medical screen is equipped with an automatic calibration function to maintain image quality; Ordinary monitors do not have this function, and they are prone to color cast after prolonged use.
Certification requirements: Medical screens must pass professional medical certifications (such as FDA, CE), and ordinary displays do not have medical qualifications.
Usage scenario: Medical screens are used in professional settings such as medical diagnosis, surgery, and film reading; Ordinary monitors are used for daily purposes such as office and entertainment.
2,Main types and application scenarios of medical screens
1. Diagnostic display
Scene: Radiology, Imaging
Purpose: Diagnosis through film reading (such as X-ray CT,MRI)
Features: High resolution, high grayscale, support for DICOM standard
2. Surgical monitor
Scene: Operating room, endoscopic system
Purpose: Real time display of intraoperative images
Features: High brightness, waterproof and antibacterial, supports 4K/3D
3. Clinical review monitor
Scene: Doctor's office, ward, nurse station
Purpose: To access patient images and medical records
Features: Medium resolution, support for basic DICOM, high cost-effectiveness
4. Pathological display
Scenario: Pathology Department, Remote Consultation
Purpose: To view digital pathological sections
Features: ultra-high resolution, wide color gamut, precise color
5. Remote consultation/teaching monitor
Scenario: Remote medical care, demonstration center
Purpose: Case discussion, teaching demonstration
Features: Supports multiple screens, high-definition large screens
3, Key technical elements
1. DICOM(Digital Imaging and Communications in Medicine)
Medical screens must support the DICOM Part 14 standard, which is the brightness calibration specification for medical imaging display devices to ensure consistency in displaying grayscale images between different devices, and is a basic requirement for diagnostic level displays.
2. Automatic brightness and color calibration
High end medical displays typically have built-in brightness and color sensors that can be automatically calibrated in real-time or periodically to ensure consistent image quality over the long term.
3. Multiple grayscale support
Medical images contain a large amount of grayscale information, and medical screens typically support grayscale outputs of 10 bits or more, displaying over 1000 grayscale levels to help doctors identify tissue details more clearly.
