“…Many applications of x-ray CT occur in a busy clinical environment, where fast workflow is a necessity. For this reason, image reconstruction scientists have also devoted important effort to the development of fast algorithms, by using more efficient mathematical reformulations, [165][166][167][168] or by identifying ways to benefit from novel computing hardware. [169][170][171][172][173] Such developments have been and remain critical as CT image reconstruction is evolving from linear to nonlinear methods, either with optimization techniques or deep learning paradigms or with a combination of these tools.…”

Purpose: For 50 years now, SPIE Medical Imaging (MI) conferences have been the premier forum for disseminating and sharing new ideas, technologies, and concepts on the physics of MI.Approach: Our overarching objective is to demonstrate and highlight the major trajectories of imaging physics and how they are informed by the community and science present and presented at SPIE MI conferences from its inception to now.Results: These contributions range from the development of image science, image quality metrology, and image reconstruction to digital x-ray detectors that have revolutionized MI modalities including radiography, mammography, fluoroscopy, tomosynthesis, and computed tomography (CT). Recent advances in detector technology such as photon-counting detectors continue to enable new capabilities in MI. Conclusion:As we celebrate the past 50 years, we are also excited about what the next 50 years of SPIE MI will bring to the physics of MI.
