Synthetic x-ray computed tomography (CT) images derived from magnetic resonance imaging (MRI) is a recent area of focus for medical imaging researchers for applications in attenuation correction in simultaneous PET/MRI systems and MRI-guided radiotherapy planning. Several research groups have demonstrated the potential of deep learning to generate the synthetic CT images, however, there are several major open questions that remain with this approach. We investigated how the selection of MRI inputs affect the resulting output using a fixed network. We found that Dixon MRI may be sufficient for quantitatively accurate synthetic CT images and ZTE MRI may provide additional information to capture bowel air distributions.
Hemodynamic activities in the prefrontal cortex are investigated during noxious thermal stimulation over the right Forearm, right TMJ, and left Forearm. Robustness of prefrontal hemodynamic responses during noxious th...

The mechanical properties of a new class of bioabsorbable polymer/composite based on the amino acid tyrosine and calcium phosphate fibers were examined. The tensile modulus of the neat polymer was increased by more than 115% by using a plasma fiber treatment. The use of these innovative materials in fixation devices could potentially eliminate the need for a second surgery to retrieve the implant.
Microfluidic manipulation and perfusion of multicellular spheroids often utilize device geometries with relatively large channels but smaller trapping features, which are tricky to fabricate with robust bonding. Here,...
