Medical Ultrasound vs NDT: Synergy Front-End Checklist
The same Synergy ultrasound front-end PNs often show up in both medical imaging and industrial NDT BOMs. Both drive piezo probes, but the constraints differ: medical care about image uniformity, patient-side safety, and portable power; NDT cares about penetration/resolution, sustained high PRF, and field reliability. “Channel count is enough” usually fails at system bring-up.
This article does not restate the pulser+switch kit guide or portable multi-device notes (see related reading). It is a scene-difference checklist mapped to evaluable Synergy parts: pulser SY5817, HV switches SY2162QF (16ch) and SY2320FN (32ch).
Difference at a glance
| Axis | Medical imaging | Industrial NDT |
|---|---|---|
| System goal | Image quality, frame rate, portable/cart size & power | Defect detection, penetration, continuous field duty |
| Channel habit | Portable often starts at 8–16/32, then scales | Set by probe/scanner; multi-channel matrices common |
| TX focus | 3-level/return-to-zero, symmetry, harmonics, clean T/R | Pulse energy, PRF, and thermal steady-state matter more |
| Switch focus | Low charge injection, isolation, crosstalk → noise/artifacts | Same isolation/crosstalk; bleed + rise under long duty |
| Compliance / environment | Medical electrical safety and leakage stricter | Industrial temp/vibe, EMC, dirty field power |
How to land Synergy PNs
| Role | PN | Notes | Product page |
|---|---|---|---|
| TX | SY5817 | 8ch 3-level pulser + active T/R; common start for portable medical and NDT TX bring-up | 854 |
| Switch (mid) | SY2162QF | 16ch + bleed; portable medical / lighter NDT mux | 853 |
| Switch (scale) | SY2320FN | 32ch + bleed; larger medical arrays or multi-channel NDT heads | 855 |
Higher channel counts can move to SY264x; MUX/SPST split is covered in the 32ch guide. Pulser and switch are upstream/downstream—not substitutes.
7-step scene checklist
- Pick the scene: imaging vs NDT—success metric is artifacts or defect detection/penetration?
- Channels / topology: 8 / 16 / 32 vs probe; need MUX?
- Pulse & thermal: PRF, width, case temperature—NDT continuous duty is usually tighter.
- T/R & bleed: TX/RX window and switch-side capacitive bleed.
- Isolation / crosstalk: off-isolation into the receive noise floor.
- Safety vs environment: medical leakage/isolation vs industrial vibe/EMC—do not reuse one report.
- Sampling & lead time: pilot as pulser+switch kit; datasheets on product pages; support via Jarwey.
Important: Same PN pool ≠ same acceptance criteria. Final authority is the datasheet and system measurements.
Why teams evaluate this path
- Aligns with common medical and NDT front-end needs while helping control BOM cost
- Specs are checkable on product datasheets
- Flexible delivery: sampling, small batch, and lead-time coordination by project
- Useful for evaluation fixtures, training kits, and channel kits

Takeaway
Medical imaging and industrial NDT can share the Synergy front-end evaluation pool, but must split validation by scene constraints. Start TX with SY5817, choose switch SY2162QF / SY2320FN by channel, then close thermal, isolation, and safety/environment lists before cost-down.
