Consultant for biomedical engineering research project involving task-based image analysis research studies for PET imaging.

Boston, MA, US

• Worked with a team of physicians, nurses, technologists, and programmer/analyst to ensure high quality images for patient care and clinical research.
• Supervised quality assurance/control for nuclear medicine instrumentation (PET-CT scanners, gamma cameras, dose calibrators, well counters), calibrated and tested scanner/camera performance, audited quality control.
• Authored reports that reviewed and documented quality control audits, presenting findings and recommendations for actions. Provided trending and visualization of QC data.
• Provided daily front-line support for troubleshooting issues with equipment, working with vendors’ service engineers and technologists to minimize down-time.
• Provided physics services for accreditation by the American College of Radiology (ACR) for PET-CT and Nuclear Medicine and for scanner qualification for participation in multi-center clinical trials.
• Reviewed imaging policies and procedures, implemented imaging protocols on systems, and authored quick reference guides for technologists.

US

• Co-investigator in diagnostic nuclear medicine research with an emphasis on oncology applications. Worked with a team of physicians, technologists, and information systems manager to establish a nuclear cardiology.
• Developed scan protocols for cardiac phantom imaging to qualify sites for participation in multi-center clinical trials.
• Modified heart-torso phantoms to improve durability; to increase ease of handling by technologists; to facilitate evaluation of factors affecting precision of estimates of myocardial perfusion defects; and to provide.
• Participated in launching PET-CT in the nuclear cardiology with investigations of reconstruction techniques and artifacts.
• Developed and validated Monte Carlo simulation software of photon transport in gamma cameras for applications with medium- to high-energy gamma rays.
• Produced visualization software with IDL for development of a method of co-registration and fusion of x-ray CT and SPECT image volumes.

Worcester, MA, US

• Developed and validated scatter correction and assessed the effects on lesion detection and activity estimation in SPECT imaging.
• Developed and validated Monte Carlo simulation of photon transport in gamma camera collimators for medium- and high-energy photons. Provided optional collimator routine for use with SIMIND, a SPECT camera simulation.
• Supported the needs of other researchers for Monte Carlo simulation.
• Performed UNIX system management for research workstations.
• Delivered educational presentations at conferences and wrote scientific papers for publication.
