description: This profile represents the constraints applied to the Observation resource by the pan-Canadian Patient Summary project, which specifies a radiology observation for a patient summary based on the FHIR standard R4.\n\nThis observation may represent the conclusions of a diagnostic procedure such a Chest RX, or it may group the set of results produced by that single or multi-modality procedure.\n\nIn the latter case, the main observation (this one) carries the overall conclusion of the study and/or a global interpretation by the observer of the study as value of this observation; and may references the atomic results of the study as \"child observations\".\n\nIt also allows providing details about the related study using the partOf element referring to an ImagingStudy resource.
