Final answer:
In radiation therapy EMRs, the HL7 and DICOM standards are applied to ensure the effective exchange and sharing of electronic health information and medical imaging data.
Step-by-step explanation:
The communication standards that are routinely applied in radiation therapy Electronic Medical Records (EMRs) are Health Level 7 (HL7) and Digital Imaging and Communications in Medicine (DICOM). HL7 is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. DICOM is a standard for handling, storing, printing, and transmitting information in medical imaging. It includes a file format definition and a network communications protocol. The combination of these standards ensures that systems can communicate effectively and that images and patient data can be shared across different systems within healthcare environments.
