Patent number: 11494955Abstract: For controlling reconstruction in emission tomography, the quality of data for detected emissions and/or the application controls the settings used in reconstruction. For example, a count density of the detected emissions is used to control the number of iterations in reconstruction to more likely avoid over and under fitting. The count density may be adaptively determined by re-binning through pixel size adjustment to find a smallest pixel size providing a sufficient count density. As another example, the detected data may have poor quality due to motion or high body mass index (BMI) of the patient, so the reconstruction is set to perform differently (e.g., less smoothing for high motion or a different number of iterations for high BMI). The quality of the data may be used in conjunction with the application or task for imaging the patient to control the reconstruction.Type: GrantFiled: June 10, 2020Date of Patent: November 8, 2022Assignee: Siemens Medical Solutions USA, Inc.Inventors: Alexander Hans Vija, Francesc dAssis Massanes Basi, Manjit Ray, Raymond Shi Xu
