At IIS, we are exploring the next generation of medical ultrasound imaging systems:
- LightProbe: a programmable ultrasound transducer head, which incorporates the entire analog frontend and directly outputs the captured digital samples. This allows the LightProbe to be directly connected to any commodity hardware (phone, tablet, workstation) for post-processing over a standard digital link as simple as a standard peripheral, like a camera.
- LightABVS: a high-end ultrasound probe, evolution of LightProbe, which incorporates 192 channels and communicates with a host PC via two 100G Ethernet optical links
- TinyProbe: a reduced number of channels (32), compact, wireless probe for wearable applications
- ULP-probe: an ultra-low power (20mW) probe for long-term monitoring
Ultrasound systems have two main challenges: the high data-rates produced by the frontend (which need to be processed and transported off-head), and the power/thermal constraints of such devices.
This is an ongoing project at our lab and we are looking for motivated students to contribute on the following topics:
- Implementation of processing subunits: Hardware design FPGA/ASIC (VHDL/HLS)
- Programming of software functions: Microcontroller Programming / Processing system programming (C/C++/CUDA)
- System level design: Hardware software interactions, multi FPGA system, high bandwidth links (VIVADO/IP/HW-SW Codesign)
- Power/Thermal optimization: Modelling, Control, Task Scheduling (Matlab)
- Machine Learning (Python, FPGA)
- Ultrasond imaging algorithm development/improvements/tailoring for implementation (Matlab)
- PCB Design
