During my tenure at a previous hospital, we experienced a sudden malfunction in the CT scanner during a critical patient scan. I quickly assessed the situation, consulted the equipment manual, and identified a loose connection in the power supply. I safely shut down the machine, reconnected the power source, and performed a series of diagnostic tests to ensure stability. This quick action allowed us to resume the scan without compromising patient safety or data integrity.

I prioritize patient comfort by explaining each step of the procedure in a clear, reassuring manner. I ensure they understand the importance of remaining still during the scan to avoid image blurring. For safety, I meticulously follow radiation safety protocols, minimizing exposure by using the lowest effective dose and shielding non-target areas. Regular training updates on patient handling and emergency procedures also contribute to maintaining a safe environment.

I adhere to strict calibration schedules for the CT scanner to ensure optimal performance. Regularly checking and adjusting image settings, such as kVp and mAs, helps maintain image quality. I also conduct daily quality control checks using phantoms to verify image consistency and accuracy. Collaborating with radiologists to understand their image quality requirements further enhances my ability to produce high-quality scans.

I address claustrophobia by first discussing the patient's concerns and providing a detailed explanation of the procedure. I reassure them about the duration and the sensation of the machine. If necessary, I administer mild sedation under a physician's guidance. I also ensure they are positioned comfortably and can communicate with me throughout the process. This approach helps alleviate anxiety and ensures the patient's cooperation during the scan.

I have worked with various CT scanners, including multi-slice and cone-beam models. Multi-slice scanners, with their high-speed capabilities, are ideal for cardiac and trauma imaging. Cone-beam CTs, on the other hand, are excellent for dental and maxillofacial imaging due to their high resolution and low radiation dose. Understanding the unique features of each type, such as dose modulation and image reconstruction techniques, allows me to optimize scan protocols for different clinical needs.
