Portable Ultrasound for Rural Uganda Reducing cost Easy to use Portable  

Overview of Implementation Plans  Devices and Development Tools:    Netbook  - Touch screen Lenovo IdeaPad S10-3t LabView - User Interface and Generating Image Probe SDK - Image rendering Important Change: No Controller               Reason: Use of touch screen

Building on Winter 2010 Fieldwork guiding implementation choices Efficiency is key Touchscreen No keyboard searching Simplify Only necessary features   Learning from our prototype Simplify even more No controller No mmode No authentication

What have you accomplished so far? Hardware Touch screen netbook Controller Image Acquisition Connected and initialized probe to PC Manipulated SDK to acquire ultrasound image from the USB Can send images from probe to interface User Interface Built login, menu, scanning, and image post processing screens

Prototype Demonstration

Evaluation Plan Usability evaluation Need midwives, ultrasound technicians, and teachers. Midwives to evaluate ease of use, learnability Ultrasound technicians to evaluate workflow, appropriateness of included features Ultrasound teacher to illustrate areas in which software can be used as an educational tool (e.g. suggestions for high-level conceptual content to include in the Help section) Technical evaluation Need to investigate memory usage, CPU usage, frames per second.   Alexis

What is left to do? Improve speed Add additional controls for the probe  adjusting gain depth Add additional UI features  image markup measurements patient record browsing help section settings zoom Implement data storage
