Group PhotoThe Photon Migration Imaging laboratory at the Athinoula A. Martinos Center for Biomedical Imaging is exploring new ways to investigate the brain and breast non-invasively and without using harmful, ionizing radiation. The lab is working to develop the optical imaging technology as well as apply it for a wide range of basic science and clinical studies. Ultimately, these studies could contribute to better understandings of how the brain works as well as improved screening and detection of a variety of pathologies.

What's New In The PMI Lab?

November 24, 2010: The optics community lost a friend last week. Britton Chance, a giant in the field, died on Tuesday, November 16. Read about Dr. Chance's life and work here.

November 10, 2010: The Optical Imaging Lab's work developing a combined optical/x-ray imaging system capable of obtaining both structural and functional information of the breast, which is reported in the online edition and January issue of Radiology, has been highlighted by several media outlets, including CBS Boston, HealthImaging.com, Ivanhoe and MedPage Today. The work is a collaborative effort with Dr. Daniel Kopans and colleagues at the Breast Imaging Center at MGH. Read the abstract here.

September 2, 2010: Sakadzic et al.'s recent Nature Methods paper is the subject of a News and Views article in the same issue. Check it out: Dirnagl, U. "Oxygen maps in the brain." Nat Methods 7(9):697-699.

August 9, 2010: PMI investigator Vivek Srinivasan and colleagues at ThorLabs Inc. and MIT have published an article in the SPIE Newsroom: Doppler optical coherence tomography for imaging of brain hemodynamics.

August 8, 2010: Sakadzic et al.'s Nature Methods paper, " Two-photon high-resolution measurement of partial pressure of oxygen in cerebral vasculature and tissue," has been published online. Nature Methods issued a press release about the paper. We've reproduced it here.

COSMOS magazine has already written about the study. Read the article here.

June 29, 2010: Our own Dr. Fang's paper on GPU 300x acceleration over CPU for Monte Carlo simulations of photon migration has created quite the stir in the debate of GPU vs CPU as a counter claim to Intel's claim that GPU's are only 14x faster than CPU's. See this blog post for more details. You can find the relevant discussions here.

June 28, 2010: A recent study from the PMI Lab - "Quantitative cerebral blood flow with Optical Coherence Tomography" - was written up in the Research Highlights section of the April 2010 issue of Nature Photonics.

May 21, 2010: Registration is open for the conference on functional Near Infrared Spectroscopy, to be held October 15-17. This meeting, which will coincide with the NIRS-DOT Visiting Fellowship Program (October 14-15), will bring together a diverse group of fNIRS users and developers to discuss the rapidly growing application areas for the technique and recent technological advances.

March 11, 2010: Registration is now open for the 2010 NIRS-DOT Visiting Fellowship Program.

February 6, 2010: We are currently recruiting for two different positions: a research assistant in optical breast imaging, and a graduate student/postdoctoral fellow in multimodal optical imaging.

November 20, 2009: A paper by our own Qianqian Fang is featured on the cover of the Oct. 26 issue of Optics Express. (animated gif on right). The paper described a blazing-fast GPU-based parallel Monte Carlo simulation software, which is now available for download.

October 29, 2009: We are already looking forward to next year's NIRS-DOT Visiting Fellowship Program. The 2010 course will be held on the 14th and 15th of October.

July 30, 2009: The PMI Lab is pleased to announce that the NIRS-DOT Visiting Fellowship Program will be held on October 15 and 16 in Charlestown, Mass. Details can be found here.

February 7, 2009: Devor et al.'s 2008 Journal of Neuroscience paper -- "Stimulus-induced changes in blood flow and 2-deoxyglucose uptake dissociate in ipsilateral somatosensory cortex" -- was highlighted in “This Week in the Journal” in the issue in which it appeared as well as in the February 2009 issue of Nature Reviews Neuroscience.

January 29, 2009: MedicalPhysicsWeb interviewed Rickson Mesquita for an article about a PMI Lab study reported in a recent issue of Phys. Med. Biol. The article, "Model links brain's functional processes," can be found here (password required).
