Mike Murphy Mike Murphy. While the DICOM standard has achieved a near universal level of acceptance among medical imaging equipment vendors and healthcare IT organizations, the standard has its limitations. HL7 and DICOM manage a joint Working Group to harmonize areas where the two standards overlap and address imaging integration in the electronic medical record. Many radiology departments are successfully using the transactions defined by SWF to exchange data for radiology procedures. An imaging examination, more commonly abbreviated imaging exam or imaging study, contains all the images acquired in a given imaging protocol. The DICOM information object definitions[16] encode the data produced by a wide variety of imaging device types,[17] including, CT (computed tomography), MRI (magnetic resonance imaging), ultrasound, X-ray, fluoroscopy, angiography, mammography, breast tomosynthesis, PET (positron emission tomography), SPECT (single-photon emission computed tomography), Endoscopy, microscopy, nd whole slide imaging, OCT (optical coherence tomography). The administrative steps involve a patient being registered, a Diagnostic Imaging Order being placed for the registered patient, a unique Accession Number assigned, and the order being scheduled as a Requested Procedure. 5 or more.
