Advanced Motion Correction Methods in PET

With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...

Respiratory motion correction in prostate cancer positron emission tomography: A study on patients and phantom simulation

Introduction: To investigate the effects of breathing cycle and tree diaphragm motions on prostate cancer tumors standard uptake value (SUV) during positron emission tomography (PET) and to correct it. Materials and methods: Respiratory motion traces were simulated on the common patient breathing cycle and tree diaphragm motio...

Motion Correction

Patient motion has long been recognised as a problem in MR imaging. A 1997 study of 297 first-time adult MRI patients showed 6.4% of scans were of impaired diagnostic quality due to motion [1]. These numbers are described by the authors as being inline with an earlier German study of 21,000 cases (8-17% scans of impaired diagnostic quality) [2]. Despite modern hardware and reconstruction, motio...
