SPECT Imaging Dose Optimization via Annular View ROI Analysis

The patent applies local quality by transitioning from a uniform protocol applied to all patients to patient-specific optimization. The system calculates individualized scan times and radiation doses based on each patient's anatomical characteristics, weight, and clinical requirements. This allows the imaging protocol to be tailored locally to each patient's needs while maintaining overall system simplicity through automated calculations.

The patent implements dynamics by making scan time a variable parameter rather than a fixed value. The system dynamically adjusts scan time based on patient-specific factors including weight, body habitus, and clinical indications. This dynamic adjustment allows the system to maintain image quality standards while optimizing scan time for each patient, thereby improving overall productivity without sacrificing diagnostic quality.

The patent applies parameter changes by systematically adjusting multiple imaging parameters including radiation dose, scan time, and acquisition protocols. The system calculates optimal parameter combinations based on patient characteristics to achieve the lowest possible radiation dose while maintaining diagnostic image quality. This involves changing dose parameters in conjunction with scan time and other acquisition parameters to preserve diagnostic reliability.

The patent implements self-service by enabling the system to automatically calculate and determine optimal imaging parameters without requiring manual intervention from the operator. The system autonomously processes patient data, performs calculations for optimal scan time and radiation dose, and generates the imaging protocol. This self-service capability maintains high image quality optimization while keeping the user interface simple and easy to operate.
