Leaving The Dark Side - Developing a C++ Based Medical Device
summary
Mammography workstation built in C++ Qt viewer handles up to 4 GB uncompressed pixel sets, two 5MP 10‑bit grayscale displays and up to 24 clients, sustaining <1s for changing up to eight images because radiologists read ~120 patients/hour. Development moves from waterfall to Scrum with CI and heavy test automation using RSpec + Spec + Ruby driving behavior, unit and UI tests; tests call services via XML‑RPC to an IPC aspect center. Result: thousands of installs (6–7k), earlier 8–12 week releases and many patches shrink to a maximum two‑week release.
