About
Alexander Gottschalk is a medical physicist and clinical researcher whose work sits at the intersection of stereotactic body radiotherapy (SBRT), robotic radiosurgery, and treatment planning optimization. His research has made meaningful contributions to the precision and safety of radiation therapy, with a particular focus on CyberKnife-based treatments for prostate, lung, and brain cancers. Gottschalk's most influential work—garnering 55 citations—evaluated the clinical advantages of a CyberKnife system equipped with a multileaf collimator, demonstrating its versatility across both SBRT and standard IMRT applications. His investigations into lung tumor motion tracking have clarified when dynamic real-time tracking outperforms static vertebral alignment methods, directly informing patient eligibility decisions. Equally impactful is his research revealing how interfraction anatomical variability in prostate SBRT can significantly elevate rectal dose, underscoring the importance of adaptive planning strategies. Beyond clinical investigations, Gottschalk has contributed to treatment planning standardization—developing objective dose constraint criteria for prostate SBRT—and to algorithmic accuracy, comparing Monte Carlo and ray-tracing dose calculation methods. His more recent work exploring deep learning frameworks for fiducial-free respiratory motion tracking signals a forward-looking engagement with artificial intelligence in radiotherapy. Across his career, Gottschalk's research has consistently prioritized translating technical innovations into measurable improvements in patient outcomes.
