  /// Observations generated by imaging. The scope includes observations regarding plain x-ray, ultrasound, CT, MRI,
  /// angiography, echocardiography, and nuclear medicine.
  case imaging
  
  /// The results of observations generated by laboratories.  Laboratory results are typically generated by
  /// laboratories providing analytic services in areas such as chemistry, hematology, serology, histology, cytology,
  /// anatomic pathology (including digital pathology), microbiology, and/or virology. These observations are based on
  /// analysis of specimens obtained from the patient and submitted to the laboratory.
  case laboratory
  
  /// Observations generated by other procedures.  This category includes observations resulting from interventional
  /// and non-interventional procedures excluding laboratory and imaging (e.g., cardiology catheterization, endoscopy,
  /// electrodiagnostics, etc.).  Procedure results are typically generated by a clinician to provide more granular
  /// information about component observations made during a procedure.  An example would be when a gastroenterologist
  /// reports the size of a polyp observed during a colonoscopy.
  case procedure
  
  /// Assessment tool/survey instrument observations (e.g., Apgar Scores, Montreal Cognitive Assessment (MoCA)).
  case survey
  
  /// Observations generated by physical exam findings including direct observations made by a clinician and use of
  /// simple instruments and the result of simple maneuvers performed directly on the patient's body.
  case exam
  
  /// Observations generated by non-interventional treatment protocols (e.g. occupational, physical, radiation,
  /// nutritional and medication therapy)
  case therapy
  
  /// Observations that measure or record any bodily activity that enhances or maintains physical fitness and overall
  /// health and wellness.  Not under direct supervision of practitioner such as a physical therapist. (e.g., laps
  /// swum, steps, sleep data)
