GSV / SSV Mapping
- Mode: B-mode, transverse orientation
- Frequency: 10–14 MHz superficial, 7–10 MHz deep thigh
- Depth: 2–4 cm (just below the fascia)
- Gain: Moderate — vein lumen anechoic, walls well-defined
- Focus: At the level of the vein
- Probe pressure: Minimal — excessive pressure underestimates diameter
Venous Reflux Assessment
- Color Doppler PRF: 1000–1500 Hz
- Wall Filter: Low (50–100 Hz)
- Color Gain: Just below artifact threshold
- Spectral Gate: 2–3 mm
- Angle Correction: 60 degrees or less
- MX7/M8 Elite: Enable Smart Track
- Resona i9T: Enable V Flow at junctions for angle-independent assessment
DVT Compression Exam
- Mode: B-mode, transverse orientation
- Frequency: 7–12 MHz linear; 3–5 MHz curved for deep/large patients
- Depth: 3–5 cm (femoral), 4–6 cm (popliteal)
- Color Doppler PRF: 1000–2000 Hz for flow confirmation after compression
- Augmentation: Distal calf squeeze for color Doppler confirmation
Sclerotherapy Guidance
- Frequency: 12–14 MHz
- Depth: 1.5–3 cm (minimum needed)
- Gain: Slightly above normal for needle visibility
- Beam Steer: ON to optimize needle angle
- Frame rate: Maximize by reducing depth and narrowing field of view
- Compound imaging: Reduce or disable if needle artifact is weak
Perforator Assessment
- Frequency: 10–14 MHz
- Depth: 3–5 cm (to include muscular fascia)
- Color Doppler PRF: 500–1000 Hz (low to detect slow flow)
- Wall Filter: Lowest available
- Resona i9T: Enable UMA for micro-flow detection
- Augmentation: Distal calf squeeze to provoke outward flow
Post-Procedure Surveillance
- Mode: B-mode + Color Doppler
- Use same preset as initial mapping exam for consistency across visits
- PRF: Low for residual and recanalization flow detection
- Resona i9T: UMA for micro-recanalization channels
Frequently Asked Questions
Are these settings the same across all Mindray systems?
These are starting-point settings that apply across MX7, M8 Elite, Resona i9T, and Consona N9. The physics and clinical targets are the same — specific menu paths vary slightly by model.
Can I save these as a preset?
Yes. Configure these settings in the appropriate exam mode and save them as your default preset. Capital Health Solutions configures this during system setup.
Do I need different settings for large vs. small patients?
Yes. Larger patients require lower frequency (7–10 MHz) and increased depth. Smaller or pediatric patients benefit from higher frequency (12–14 MHz) and shallower depth.
