Adaptive Tomosynthesis Angle Control for Breast Density

The imaging system dynamically adjusts the tomosynthesis angle range based on the detected breast type. For dense breasts, a wider angle range is used to improve penetration and visualization, while for fatty breasts, a narrower angle range suffices. This dynamic adaptation optimizes diagnostic accuracy for each breast type without requiring multiple fixed imaging configurations.

The system changes the imaging parameter (tomosynthesis angle range) according to the breast type classification. By detecting breast density and composition, the system selectively applies different angle ranges (e.g., wider angles for dense breasts, narrower for fatty breasts), thereby optimizing image quality and lesion detection while avoiding unnecessary complexity of universal high-angle imaging.

The system applies different imaging conditions (angle ranges) to different local characteristics of breast tissue. Dense breast regions receive wider angle imaging with higher radiation dose to ensure adequate penetration and visualization, while fatty breast regions receive narrower angle imaging with lower radiation dose, as they require less penetration. This localized optimization ensures adequate image quality while minimizing unnecessary radiation exposure.

The imaging angle range parameter is changed based on breast type detection. For dense breasts, a wider angle range is selected to improve image quality despite higher radiation dose. For fatty breasts, a narrower angle range is selected to maintain adequate image quality with reduced radiation dose. This parameter adaptation resolves the contradiction between image quality and radiation exposure.

The system tailors the imaging angle range to the specific breast type characteristics. Fatty breasts with lower density receive narrower angle ranges with reduced radiation dose, as adequate visualization is achieved with less penetration. Dense breasts receive wider angle ranges with higher radiation dose to ensure sufficient penetration and lesion detection. This localized optimization ensures each patient receives the minimum necessary radiation for adequate diagnostic quality.

The tomosynthesis angle range parameter is dynamically changed based on breast type classification. For fatty breasts, a narrower angle range is applied to reduce radiation dose while maintaining adequate image quality. For dense breasts, a wider angle range is applied to ensure sufficient penetration and lesion detection despite higher radiation dose. This adaptive parameter selection resolves the contradiction between radiation dose and detection accuracy.

The imaging system automatically detects breast type and selects appropriate imaging parameters without requiring manual intervention or complex protocol selection by the operator. The system self-adjusts the tomosynthesis angle range based on detected breast density, thereby maintaining ease of operation while improving diagnostic accuracy for dense breasts through automated parameter optimization.

The system incorporates feedback from breast type detection to automatically adjust imaging parameters. By detecting breast density and composition, the system provides feedback that triggers selection of appropriate tomosynthesis angle ranges, thereby improving diagnostic accuracy for dense breasts without complicating the operator workflow. The feedback loop ensures optimal imaging parameters are applied based on actual breast characteristics.
