Hi!
Echocardiography is of course only one of many ultrasound examinations that we want an imaging pattern to work for, but it is a suitably complex example involving many methods and several calculated values that can be reached in more than one way. In addition to ultrasound other modalities (e.g. MR-imaging) can also be used to measure the same heart dimensions, blood flow etc.
General examples:
The page Riktlinjer - Ekokardiografi links to many references regarding Echocardiography that may be useful for this modeling work.
openEHR-specific examples:
The German Echocardiography template https://ckm.highmed.org/ckm/templates/1246.169.85 from HiGHmed is a pretty good example report regarding interesting data points (although I suggest some modeling/terminology improvements in the original post above)
The corresponding Swedish experiment is slowly being built up at https://github.com/modellbibliotek/klinfys-register. Right now, when writing this, the most recent half-way template attempt is in the file klinfys-register/Echo.t.json at master · modellbibliotek/klinfys-register · GitHub
It extends and modifies the HiGHmed template a bit and using a modified openEHR-EHR-CLUSTER.imaging_result.v0 archetype with "Result name " added as described above.
