Ultra Low Dose CT (ULDCT) further minimizes radiation exposure beyond standard low-dose scans, offering safe, effective imaging, especially for pediatric patients or those needing repeated scans. Advances in scanner technology and image reconstruction algorithms allow high-quality diagnostic images even at ultra-low radiation levels. ULDCT is commonly used for lung imaging, sinus scans, and follow-up exams where frequent monitoring is required. This technique is gaining popularity in Perth and globally due to its patient-centered approach, balancing diagnostic clarity with long-term health safety, ensuring critical insights with minimal exposure.
