Image segmentation and computer vision applications in nuclear medicine.
Above figure illustrates the degradation of a SPECT transverse slice through the chest by photon attenuation, the acquisition of scattered photons, and the finite imaging system spatial resolution.
At left side is the true source distribution in this simulated image. Note the shape edges and uniform intensity through the soft tissues, lungs, liver, and heart.
Reconstruction of simulated projections from this distribution look exactly like the source distribution in the absence of attenuation, scatter, and system spatial resolution illustrating the success of reconstruction methods with ideal data.
At the left is the slice reconstructed from data which has included the impact of attenuation, scatter, and system spatial resolution. Note the variation in intensity in regions of uniform source distribution, and distortation in shape.
Bringing compensation strategies for such degradations into the clinical use is the MAJOR GOAL of our research efforts.
To learn more about SPECT compensation strategies for these degradations you can read a PDF file with our review chapter on this topic.

Post-Doctoral Fellowship in Nuclear Medical Physics
A three-year Post-Doctoral Fellowship in Nuclear Medical Physics will be available at Department of Radiology of the University of Massachusetts (UMass) starting 1-October-2016, or thereafter. The position is designed to train recent graduates to work as a medical physicist in an academic department, clinical position, or in industry. The successful candidate will participate in ongoing research in single photon emission computed tomographic (SPECT) imaging and reconstruction. The facilities available to nuclear medical imaging research at UMass include excellent office/research space, access to a large cluster facility, and the imaging systems in the clinic.
Candidates must have a doctoral degree in medical physics, physics, applied mathematics, engineering, or computer science. Proven expertise in C programming, and working with Linux and Windows workstations is required. Experience with tomographic imaging and reconstruction, collimator design, image processing, advanced mathematics, Monte Carlo simulation, and MATLAB is desired.
To apply send a letter of application detailing relevant experience and career objectives, a curriculum vitae, and the names of three references to: Michael A King, PhD, Division of Nuclear Medicine, The University of Massachusetts Medical School, 55 Lake Ave North, Worcester, MA 01655, call Dr King at (774) 442-4255, or send an e-mail to Michael.King@umassmed.edu.
