Philosophy of Care
Dr. Wray's philosophy of care is patient first. He believes patient education, empowerment, and empathy are the key elements to achieve high-value care. In this personalized setting, he strives to incorporate technology and design thinking to define best practices.
Dr. Wray is a molecular imaging specialist and nuclear medicine physician. He provides imaging consultation for oncology, cardiology and internal medicine as well as minimally invasive radioactive therapy for endocrinology and oncology. He has particular clinical interest and expertise in PET/CT.
Dr. Wray's research focuses on machine learning and radiomics in oncologic molecular imaging. Utilizing novel dynamic PET/CT quantitative imaging features and biomarkers he is creating large imaging databases combined with artificial intelligence to improve outcomes for cancer patients and provide personalized care.
