“…Radiographic visibility can be reached at acceptable dose perturbations using e.g. 0.9 mm diameter, 3.1 mm long cylindrically shaped stainless steel marker for prostate therapy (Newhauser et al 2007). Finally, the additional imaging dose delivered to the patient can result into a significant dose contribution to the patient's skin if fluoroscopy is used throughout treatment delivery (Shirato et al 2004).…”

Charged particle beam radiotherapy requires dedicated measures to compensate for the dosimetric influence of inter- and intra-fractional target motion. Independent of the delivery technique, these measures have to incorporate the strong influence of the radiological depth on the delivered dose. For scanned beam delivery, interference effects of target motion and scanned beam can further cause under-dosage of the clinical target volume despite using margins. Within the scope of this review, published data with respect to motion management in scattered as well as scanned beam treatment delivery will be summarized. Based on a section covering the dosimetric impact of organ motion, motion management during treatment planning, patient positioning, treatment delivery and treatment validation will be summarized. For scattered beam delivery, the concepts and data are often based on clinical usage since treatment of moving tumors has been performed for several years. In the field of scanned beam delivery, the report focuses on the results of research on countermeasures of the interference effect. Clinical application of these techniques can be expected in the near future.

“…This code is often used for modelling medical applications of proton beams. All physical models describing energy loss and scattering of the incident protons and secondary particles as well as physical databases have been specified by other authors (Herault et al 2005), (Newhauser et al 2005), (Koch et al 2008). To tally the energy deposition like here in water a rectangular and cylindrical energy deposition mesh tally type 3 was used.…”

In ocular proton therapy the important parameters range and modulation of the proton field are calculated by a simple geometric ray tracking. Due to the assumed homogeneous eye tissue, the relative-to-water proton stopping power is nearly constant within the radiation field. In cases when silicone oil tamponades are used, this will no longer hold. CT-data which are necessary to estimate the path length of protons within the oil show bigger attenuation of x-rays then in eye tissue. The use of a CT-calibration curve to deduce the relative-to-water electron density for proton stopping power calculation would be misleading giving a value of 1.05 and thus a higher proton stopping power. In reality the relative-to-water electron density is smaller, namely 0.95, leading to a proton range prolonged by about 11% of the path length within the silicone oil, if the demand for the range adjustment would not be recognized (missing information from ophthalmologists or no CT data). This finding is congruent in analytical and Monte Carlo calculations as well as in experimental investigations, being presented here. The misleading result of the CT calibration curve is explained and therapeutic consequences are demonstrated. Multiple Coulomb scattering in silicone oil does not affect the size of the planed irradiation field.
