✍️ Sample CPAS Questions & Answers
1. Why is compliance with DICOM and HL7 standards critical in PACS?
Compliance with DICOM and HL7 standards is critical because these standards provide a common framework for medical imaging and healthcare data exchange. DICOM ensures that images can be shared and viewed across different imaging devices and PACS, while HL7 standardizes the exchange of patient information between various clinical systems. Together, they guarantee seamless interoperability, accurate data sharing, and efficient workflows across the healthcare enterprise.
2. Which IHE transaction is responsible for sending a completed study notification back to the RIS after images are stored in PACS?
RAD-13 (Modality Images Stored) notifies the image manager/PACS that a modality has completed storing images, triggering downstream RIS status updates.
3. What component connects imaging modalities with PACS?
The DICOM (Digital Imaging and Communications in Medicine) interface is the essential component that connects imaging modalities, such as CT scanners and MRI machines, with a PACS. DICOM is the universal standard for handling, storing, printing, and transmitting information in medical imaging. This interface ensures that images and associated patient data can be seamlessly transferred, viewed, and archived within the PACS, maintaining data integrity and interoperability.
4. Which component ensures routing of imaging studies in workflow systems?
The workflow engine is the component that ensures the efficient routing of imaging studies within a PACS and RIS workflow system. It automates and manages the sequence of tasks, rules, and data flow from image acquisition to interpretation and reporting. By orchestrating the movement of studies and related information, the workflow engine optimizes efficiency, reduces manual errors, and ensures that studies reach the appropriate radiologists and clinicians promptly.
5. How frequently should PACS hard drive SMART (Self-Monitoring, Analysis and Reporting Technology) status be reviewed as part of preventive maintenance?
Monthly SMART status checks allow administrators to detect early warning signs of drive degradation and schedule replacements before an unplanned failure causes data loss.
6. When applying core principles in practice, what should be the first consideration?
Safety and compliance with established standards must always be the primary consideration when applying professional principles.
