Ultrasound Positioning Controller
Precision 5-axis motion system for medical imaging equipment
A client came to us after another firm delivered a board with electromagnetic interference issues and manufacturing defects. The original design used five separate driver boards connected by complicated custom connectors and cabling, which was very labor intensive to assemble.
We consolidated everything onto a single 6-layer PCB with TI-based motor drivers for all five axes controlling ~20W of low-inductance motors. A TI C2000 series MCU handles real-time control. USB-C provides both power and communication.
Achieved +/-0.1mm positioning accuracy. Eliminated spurious emissions and now passes both radiated and conducted emissions testing. Passed IEC 60601 medical pre-compliance on first attempt. Final design was 3x smaller and 10x cheaper than the original.
