Brain Imaging on WCAX

On December 27, 2012, WCAX–a television station based out of Burlington, VT–aired a news segment on a collaborative research project between the Thayer School of Engineering, the Norris Cotton Cancer Center, and the Dartmouth-Hitchcock Medical Center. The segment explains a new cancer imaging technique developed at Dartmouth that makes small brain tumors easier to see [...]

NIRFAST 7.2

Written by Hamid Dehghani in 2001, Near-Infrared Fluorescence and Spectral Tomography (NIRFAST) is an open source software package that allows users to model Near-Infrared light transport in tissue. Currently, Michael Jermyn, a graduate student in Dartmouth’s Optics in Medicine Laboratory, is moving the program to an open source platform and developing a number of new user [...]

Fluorescence Tomography

Molecular Therapy has the potential to improve the prognosis for difficult to treat cancer types, including glioblastoma multiform and pancreatic cancer. By targeting tumors, this non-invasive form of treatment delivers drugs directly to cancerous cells without damaging healthy tissue. Currently, this approach to molecular imaging is being tested at the Dartmouth Hitchcock Medical Center (DHMC). [...]

Combining NIRST and BTS

While screen-film mammography has been proven to reduce the mortality of the disease, the screening method has its limitations. As Professor Keith Paulsen explains in this video published by the Thayer School of Engineering, doctors often find the images created by mammography difficult to read due to “tissue overlap”—a type of distortion that occurs when [...]

DCCNE Featured in NH Magazine

On Monday, October 1st, the cancer research conducted by the Dartmouth Center for Cancer Nanotechnology Excellence (DCCNE) was featured on the website of NH Magazine. The article explains a number of non-invasive cancer treatment approaches, including targeted drug delivery. DCCNE is funded by $12.8 million grant from the National Cancer Institute (NCI). Each year, members [...]

Prototype Testing in China

Located on the second floor of the Dartmouth Hitchcock Medical Center (DHMC), the Advanced Imaging Center houses several imaging devices used by the Optics in Medicine Laboratory. Currently, graduate student Michael Mastanduno is testing a prototype that combines Magnetic Resonance Imaging (MRI) with Optical Tomography into a singular imaging device. This has the potential to [...]
