1. Improving proton therapy planning with photon-counting spectral computed tomography
University essay from KTH/FysikAbstract : Proton radiation therapy is an alternative to conventional photon radiation therapy, which accounts for the majority of radiation treatments today. The rationale for using protons in radiation therapy lies in their dose deposition properties; photons deposit a radiation dose inversely proportional to the energy, and therefore tissue depth, while protons exhibit a sharp Bragg peak when traversing matter.

3. Iodine Quantification Using Dual Energy Computed Tomography and applications in Brain Imaging
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Dual Energy Computed Tomography (DECT) have been clinically available for over ten years. Two such systems are currently used at Skane University Hospital (SUS) in Lund. By utilizing materials different attenuating properties at different energies, material decomposition and iodine quantification is possible. READ MORE

4. Dual Energy CT as a Foundation for Proton Therapy Treatmen Planning - A pilot study
University essay from Umeå universitet/Institutionen för fysikAbstract : The treatment plan for radiation therapy with protons is based on images from a computed tomography (CT) scanner. This is problematic since the photons in the x-ray beam from the CT scanner and the protons are affected differently by the tissue in the patient, which introduce an uncertainty in the track length of the protons.
