100 CRTTS Interview Questions and Answers

  1. What is CRTTS?

    • Answer: CRTTS stands for Computerized Radiology & Telecommunication & Telemetry Systems. It encompasses the technologies and systems used for acquiring, processing, storing, transmitting, and displaying medical images and related data, often in a networked environment.

  2. Explain PACS.

    • Answer: PACS, or Picture Archiving and Communication System, is a computerized system for the acquisition, storage, retrieval, distribution, and display of medical images. It's a critical component of CRTTS, allowing for efficient management of large volumes of image data.

  3. What is DICOM?

    • Answer: DICOM (Digital Imaging and Communications in Medicine) is a standard for handling, storing, printing, and transmitting information in medical imaging. It ensures interoperability between different imaging devices and systems within a CRTTS environment.

  4. Describe HL7.

    • Answer: HL7 (Health Level Seven) is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. It's often used in conjunction with DICOM within CRTTS to manage patient data and integrate with other hospital systems.

  5. What are the benefits of a CRTTS system?

    • Answer: Benefits include improved image quality, faster access to images, reduced storage space, enhanced collaboration among healthcare professionals, improved workflow efficiency, and better patient care through quicker diagnoses.

  6. What are some challenges in implementing a CRTTS system?

    • Answer: Challenges include high initial costs, integration complexities with existing systems, the need for specialized IT infrastructure, data security and privacy concerns, and the requirement for comprehensive staff training.

  7. Explain the role of a RIS in CRTTS.

    • Answer: RIS, or Radiology Information System, manages patient scheduling, orders, reports, and billing information related to radiology procedures. It integrates with PACS to provide a complete radiology workflow solution.

  8. What is the significance of image compression in CRTTS?

    • Answer: Image compression reduces storage space and transmission time for medical images without significant loss of diagnostic information. Various lossy and lossless compression techniques are used.

  9. Discuss the importance of data security in CRTTS.

    • Answer: Data security is paramount in CRTTS to protect sensitive patient information from unauthorized access, use, disclosure, disruption, modification, or destruction. This involves implementing robust security measures like access controls, encryption, and audit trails.

  10. What are some common image modalities used in CRTTS?

    • Answer: Common modalities include X-ray, CT (Computed Tomography), MRI (Magnetic Resonance Imaging), Ultrasound, Mammography, Fluoroscopy, and Nuclear Medicine.

  11. What is a modality worklist?

    • Answer: A modality worklist is a list of examinations scheduled for a particular imaging modality. It helps technicians efficiently manage and prioritize their workload.

  12. Explain the concept of image annotation in CRTTS.

    • Answer: Image annotation allows radiologists and other healthcare professionals to add text, voice notes, or other annotations directly to medical images for improved communication and documentation.

  13. What is the role of a teleradiology system in CRTTS?

    • Answer: A teleradiology system facilitates the remote interpretation of medical images, allowing radiologists to access and analyze images from anywhere with a secure network connection.

  14. Describe the process of image archiving in CRTTS.

    • Answer: Image archiving involves storing medical images securely and reliably using various storage technologies, such as disk arrays, tape libraries, and cloud storage, ensuring long-term accessibility and preservation.

  15. What is image retrieval in CRTTS?

    • Answer: Image retrieval is the process of quickly and efficiently accessing stored medical images based on various criteria such as patient name, date of examination, or modality.

  16. Explain the importance of image quality assurance in CRTTS.

    • Answer: Image quality assurance is crucial to ensure that medical images are of sufficient quality for accurate diagnosis. This involves regular testing and calibration of imaging equipment and adherence to quality control protocols.

  17. What are the different types of image storage used in CRTTS?

    • Answer: Different types include short-term storage (e.g., disk arrays for quick access), long-term storage (e.g., tape libraries for archival purposes), and cloud-based storage (for offsite backup and disaster recovery).

  18. Discuss the role of AI in modern CRTTS.

    • Answer: AI plays an increasingly important role, assisting with tasks like image analysis, automated reporting, and improving diagnostic accuracy. Examples include CAD (Computer-Aided Diagnosis) systems.

  19. How does HIPAA impact CRTTS?

    • Answer: HIPAA (Health Insurance Portability and Accountability Act) mandates strict regulations for the privacy and security of protected health information (PHI) in CRTTS, requiring robust security measures and compliance procedures.
