Need an m-mode, but all you have is a clip?  This tool will generate an m-mode for you along any axis you select, then allow you to measure time and distance.  It supports all major video formats as well as DICOM files. Unlike the previous online version of the tool, this standalone desktop version does not require your clip be de-identified.  If you want to learn more about how this works, check out the M.mode.ify Theory page.  Working on the Windows version now.

A 49-year-old male presents with upper back pain. He describes the pain as sharp, intermittent, and worse with deep breathing or laughing. The pain is very localized, as he points to a specific site on his left upper back. It does not radiate and has been going on since he was in a motor vehicle accident (MVA) one week ago. At that time head CT and chest xray in a local emergency department were normal. He has been prescribed muscle relaxers and NSAIDs, but they do not seem to help. He is concerned that “my spleen is lacerated!” Detailed FAST exam is negative. You then ultrasound his chest where he is hurting…
