Radiobiological Model in Radiotherapy Planning for Prostate Cancer Treatment
Quantitative radiobiological models can be used to assess the optimum clinical outcome from sophisticated therapeutic modalities by calculating tumor control probability (TCP) and normal tissue complication probability (NTCP). In this study two 3D-CRT and an IMRT treatment plans were developed with an initial prescription dose of 60 Gy in 2 Gy/fraction to prostate. Sensitivity of TCP and Compli...
متن کامل[Radiobiological pitfalls of new techniques in radiotherapy].
Radiotherapy techniques in the last decade evolved to the stage where the potential dose distribution significantly differs from earlier practices. Rotational IMRT, robotic radiotherapy or proton radiotherapy enables extremely precise dose delivery to target volumes, on the other hand, these techniques can yield a number of problems. As for photon radiotherapy, this concerns primarily the effec...
متن کاملInferring Infection Transmission Parameters That Influence Water Treatment Decisions
One charge of the US Environmental Protection Agency is to study the risk of infection for microbial agents that can be disseminated through drinking water systems, and to recommend water treatment policy to counter that risk. Recently proposed dynamical system models quantify indirect risks due to secondary transmission, in addition to primary infection risk from the water supply considered by...
متن کاملIntra-fraction dose delivery timing during stereotactic radiotherapy can influence the radiobiological effect.
The sequence of incremental dose delivery during a radiotherapy fraction can potentially influence the radiobiological effect. This would be most noticeable during the long fractions characteristic of hypo-fractionated stereotactic radiotherapy and radiosurgery. We demonstrate here the spatio-temporal variation of dose delivery by the CyberKnife to a lung tumor and propose strategies to reduce ...
متن کاملInvestigation into the radiobiological consequences of pre-treatment verification imaging with megavoltage X-rays in radiotherapy.
OBJECTIVE The aim of this study was to investigate the effect of pre-treatment verification imaging with megavoltage X-rays on cancer and normal cell survival in vitro and to compare the findings with theoretically modelled data. Since the dose received from pre-treatment imaging can be significant, the incorporation of this dose at the planning stage of treatment has been suggested. METHODS ...
