areatu/SonoForge ? reverse-engineered prompt

Build me an offline desktop app for echocardiography analysis that can open DICOM files, JPEGs, and MP4 videos, connect to PACS, and let a user review cardiac studies and make common echo measurements. I want it to support the usual clinical tools like calipers, M mode, Doppler measurements, Simpson style volume calculations, and basic reporting, with clear results shown on top of the image. It should feel usable for cardiologists and sonographers, with a clean viewer, study browser, and a portable presentation mode for showing a case on a projector while keeping the measuring tools on the laptop. Make it work in English and Russian, run fully offline, and be cross platform for Windows, Linux, and macOS. If you need current details for PACS or DICOM handling, look them up online first.
