TelemedicineDiag High-Fidelity Peripheral Examination Architecture

Digital acoustic stethoscope, 4K medical otoscope, and synchronized WebRTC diagnostic stream

Central System: Diagnostic Peripheral Hub - Lossless WebRTC Medical Media Engine

Clinical IoMT Nodes

• Digital Acoustic Stethoscope
• 4K Ultra-HD Medical Video Probe
• Lossless Audio/Video Compression Codec
• Ultra-Low Latency WebRTC Pipe
• DICOM Diagnostic Exam Capture Sink

Architectural Layers & Regulatory Standards

• Diagnostic Peripheral Hardware Interface (USB-C Medical HID / Direct Digital Audio Capture): Capturing unadulterated acoustic vibrations from chest walls and high-resolution optical video from body cavities.
• Medical Media Encoding & Filtering (Opus Full-Band Codec / AV1 Intra-Frame Compression): Preserving low-frequency heart murmurs (20-200 Hz) and lung wheezes without destructive noise suppression algorithms.
• Zero-Latency Real-Time Streaming (Selective Forwarding Unit (SFU) / Dynamic Bitrate): Maintaining lip-sync between specialist video, audio examination, and visual phonocardiogram display.
• Clinical PACS / EHR Archival (DICOM Part 10 Medical Audio & Secondary Capture): Tagging murmur audio clips and dermoscopy images with patient metadata for permanent hospital PACS archival.

Key Metrics: < 120 ms (Real-Time Glass-to-Glass Latency) | 20 Hz - 2 kHz (Auscultation Acoustic Frequency Range) | 4K UHD (Dermoscopy & Otoscopy Resolution) | 100% (DICOM PACS Archival Compliance)
