Study Looking for Volunteers

12/31/2015


The following study is currently looking for participants.

Quantitative Neurological PET/CT Imaging

Researchers at the Gordon Center for Medical Imaging in the Department of Radiology at Massachusetts General Hospital are conducting a study to evaluate the use of PET/CT imaging to investigate factors contributing to the development of neurological disorders, including Alzheimer’s disease.

We are looking for healthy volunteers who are at least 18 years of age. Participation involves answering brief questions about medical and family history, and having a PET/CT scan.
Participation may also involve having arterial blood sampling.

Procedures will take a total of about three hours on one visit day. Participants will be paid for their time and effort upon completion.

Participation is confidential.

For more information, please call Julia-Ann Scotton at 617-643-1967, Monday through Friday, 9:00am-5:00pm.

Innovation in Small Animal PET Paves Way to New Generation of Imaging Devices

12/17/2015


Dr. Réjean Fontaine, Professor at the Université de Sherbrooke in Canada, presented his work on advanced microelectronics and data acquisition for small animal PET scanner. Dr. Fontaine’s lab has developed a PET scanner that provides a powerful sub-mm image resolution for small animals. The latest version of the scanner, the LabPET-II, is based on one-to-one coupling of scintillator elements to APDs. In addition, the custom-designed electronics of the scanner were optimized to reduce stray capacitance and noise. The innovative design of the LabPET-II modular detector is expected to pave the way to a new generation of scanners for mid-size animal imaging.

Seminar: Correction of Rigid Head Motion in HCT

12/04/2015


According to the University of Sydney's Dr. Roger Fulton, a promising method of correcting for patient head motion during helical CT imaging has been developed.
The method reconstructs a motion-corrected image from an orbit that is modified based on knowledge of the head motion during the scan, which is obtained by optical motion tracking or a data-driven algorithm.
Results from real CT scans of moving phantoms, and simulations of a variety of realistic volunteer head motion patterns were shown to illustrate the ability of the method to compensate effectively for all but the most severe types of motion patients might exhibit in the clinical setting.
