Case Study: Clinical Integration of Spectral Imaging for Adaptive Radiotherapy
Context: A leading oncology center aims to enhance radiotherapy precision and patient outcomes by integrating cutting-edge imaging modalities. The objective is to move beyond standard image-guided radiotherapy (IGRT) to a fully adaptive, quantitative approach.
Challenge: Traditional Cone-Beam CT (CBCT) provides limited image quality for detailed tissue characterization, hindering true online adaptive radiotherapy. Photon-Counting CT (PCCT) offers superior spectral information and image quality, but its direct translation to daily CBCT workflows is complex due to inherent differences in acquisition and reconstruction.
Solution: The center implemented a translational framework combining HyperSight CBCT with PCCT. Leveraging machine learning, specific virtual monochromatic image (VMI) levels from PCCT were identified that highly correlate with quantitative parameters derived from HyperSight CBCT. This enabled the "translation" of detailed spectral information, usually only available from PCCT, into the CBCT workflow.
Outcome: This integration allowed for unprecedented quantitative monitoring during daily adaptive radiotherapy sessions. Clinicians could now use the enhanced image quality of HyperSight CBCT, informed by PCCT-derived spectral insights, for more precise target delineation, better assessment of tumor response, and real-time adjustment of treatment plans. This led to a significant improvement in the accuracy of radiation delivery and reduced collateral damage to healthy tissues, ultimately enhancing personalized cancer care.
