Automated Tracking of Fiducial Marker Clusters in X-Ray Images

The American Cancer Society estimates that 55,440 people will be diagnosed with and 44,330 will die of pancreatic cancer in 2018. An emerging treatment for this particularly lethal type of cancer involves utilizing extremely large and localized doses of radiation (stereotactic radiotherapy) to shrink the tumor and make patients candidates for surgical...

An Automated Method for Suppressing Artifacts in Digital Images

Drs. Timur Alexeev and Cem Altunbas of the University of Colorado Radiation Oncology department have invented an automated image correction method to suppress artifacts, such as rings, in radiographic images. It improves upon the current techniques in that it is robust, is capable or locating and suppressing such artifacts without use intervention,...

Accurate Iterative T1 Mapping Method and Algorithm to be Used with Variable Flip Angle MRI Sequence

Gadolinium-enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC) is an MR imaging technique used to determine cartilage degeneration. The current approach to dGEMRIC, however, makes clinical decision-making difficult due its poor accuracy. To address this issue, Dr. Seonghwan Yee of the University of Colorado has developed a technique that will...

Storable, Thermally Activated, Near-Infrared Fluorescent and Chemiluminescent Nanoparticles

Optical imaging is a popular research and diagnostic tool for performing quick, cost-effective and simple imaging of tumors and understanding disease pathology. However, current fluorescent dyes require a short wavelength excitation to induce luminescence which can only penetrate soft tissue up to 2 mm. This can results in inaccurate images, particularly...
