1. midwife's ultrasound wayne gerard alexis hope pratik prasad sanjana prasain mitch ishimitsu john porter alex pham matthew hicks

2. background uganda: high maternal mortality rate main complications: placenta previa, breech presentation, & multiple fetuses ultrasound imaging can detect these complications we are developing (with Dr. Rob Nathan) a portable ultrasound machine specifically for midwives, who are central to ugandan communities

3. research & design process

4. hardware lenovo ideapad s10-3t o touch screen interson AB 3.5 MHz ultrasound probe o donated o SDK provided by interson  very minimal, however  DLL written in C++ which encapsulates functions necessary to interface with probe

5. user interface originally written in LabVIEW o couldn't interface with DLLs switched to C# 2 weeks ago o no problems encountered features and workflow refined after meeting with Nicole Goldsmith, ultrasound technician ready for usability testing!

6. prototype demo

7. evaluation plans short term: o 2nd evaluation of features & workflow by UW ultrasound technician Nicole Goldsmith o usability evaluation by 2 local midwives:  both have experience working in international, resource-constrained environments (Vanuatu & Haiti) long term: o usability evaluation in Uganda

8. challenges hardware interface o unfamiliarity with tools involved  C  sdk itself  Windows API labVIEW o couldn't interface with our libraries properly o C# works great!

9. future work user testing in uganda platform-independent software patient data system more comprehensive help system
