Templates are a critical part of Structured Reports (SR); they create order for the infinite number of possible structures that one can create using the SR building blocks. A group of SR templates, and resulting dedicated SOP Classes, is defined to record and exchange the information from a catheterization lab. The information objects are part of the effort to fully digitize and integrate data flow within and beyond the cardiac catheterization laboratory. The cath procedure is an image-guided interventional procedure, involving the acquisition and analysis of images and waveforms, the administration of drugs and therapies and consultation and interaction between many medical disciplines. The cath lab is a multi-modality mix of many types of equipment from many different manufacturers. Integration of this mix involves various structured data interchanges in the cath lab. This structured data includes procedure logs, quantitative and qualitative measurements and clinical reports. It requires several specializations of the DICOM SR capabilities. One of these is the Procedure Log. One of the critical items in coordinating the information products of the cath lab is a time-stamped record of all events that occur during a procedure. This is essential to documenting the acquisition context for images, waveforms and measurements. Because the particular aspects of acquisition context that may be relevant for any specific data acquisition cannot be predetermined or known at the time of acquisition, it is crucial to have a comprehensive record of all procedural events for retrospective clinical analysis. |
