Proton therapy is gaining popularity as a tumor irradiation method due to the superior dose distribution offered by heavy charged particles. The subject of range and dose verification has been approached from several angles and fields.
Upon interaction with low-energy protons, certain nuclei undergo fusion-evaporation reactions. The resulting reaction products emit a cascade of...
Plastic scintillation detectors (PSD) are excellent candidates for in-vivo dosimetry due to their small size, sensitivity and potential for real time readout. One challenge associated with PSD dosimetry is the contamination of the scintillation signal with Cerenkov radiation and fluorescence. An implicit assumption made with PSDs is that the spectral components of the scintillator and fiber...
A prototype clinical study is being developed to assess pre-adult patients with hemophilic arthropathy. Patients with this condition experience pain in ankle, knee, wrist, or elbow joints due to joint bleeds. Typical ultrasound exams involve probe to skin contact to generate an image, which places a moderate to high level of pain on the effected joint. To overcome the physical touch of an...
TRansmit Array Spatial Encoding (TRASE) is a Magnetic Resonance Imaging (MRI) method which uses phase gradients of the $B_1$ field – rather than magnitude gradients of the $B_0$ field – to achieve spatial encoding. The potential benefits and limitations of this technique are still being explored in both conventional and low-field magnets. This work designs a highly homogeneous, low-field...
