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
research & design process
hardware
• lenovo ideapad s10-3to touch screen
• interson AB 3.5 MHz ultrasound probeo donatedo SDK provided by interson
very minimal, however DLL written in C++
which encapsulates functions necessary to interface with probe
user interface
• originally written in LabVIEWo couldn't interface with DLLs
• switched to C# 2 weeks agoo no problems encountered
• features and workflow refined
after meeting with Nicole Goldsmith, ultrasound technician
• ready for usability testing!
prototype demo
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
challenges
• hardware interfaceo unfamiliarity with tools involved
C sdk itself Windows API
• labVIEWo couldn't interface with our libraries properlyo C# works great!
future work
• user testing in uganda
• platform-independent software
• patient data system
• more comprehensive help system
