The evolution of three-dimensional conformal radiation therapy and intensity-modulated radiation therapy (IMRT) have allowed physicians to spare surrounding normal organs and reduce adverse effects. The introduction of proton beam technology and its physical advantage of depositing its energy in tissue at...
The organs at risk and their respective radiation doses are presented in Fig. 2; Table 3. Fig. 1 Radiotherapy Target Area and Field. Note: A and B represent the target area and field distribution for intensity-modulated radiation therapy (IMRT) with X-rays, respectively; C and D represent...
摘要: Compared with photon radiation (XRT), proton beam radiation therapy (PBRT) reduces dose to normal tissues, which may lead to better neurocognitive outcomes. We compared change in intelligence quotient (IQ) over time in pediatric patients with brain tumors treated with PBRT versus XRT....

Concurrent chemoradiotherapy administered with proton therapy might reduce toxicity and achieve comparable cancer control outcomes compared with conventional photon radiotherapy by reducing the radiation dose to normal tissues. Objective To assess whether proton therapy in the setting of concurrent ...
Such rapid dosing decays reduce radiation to nearby healthy tissues by a factor of 2–3. However, monitoring of treated patients for potential SPTs is a long-term proposition, and available research on SPT incidence by mode of MB treatment (proton vs. photon therapy) is currently lacking. ...

Although a CDSS was previously applied [34], [35], we have not found any application that could make quantitative decision-making about photon vs. proton therapy at three levels. A key characteristic of the system is its parallel pipeline structure, which allows easy extension by reusing the ...
