PURPOSE Mathematical models are used in Industrial & Systems Engineering to analyze complex integrated operational systems. Adapting this approach to radiation therapy can help quantify the precision and accuracy necessary to achieve optimal outcome of radiation treatment. The purpose of this work is to develop such a model using clinical data and assess the effect uncertainties have on treatme...
introduction: acoustic transient cavitation is the primary mechanism of sonochemical reaction and has potential use for tumor treatment. in this study, the in vivo anti-tumor effect of simultaneous dual-frequency ultrasound at low-level intensity (isata < 6 w/cm2) was investigated in a spontaneous murine model of breast adenocarcinoma in balb/c mice. materials and methods: forty tumor bearing m...
In recent decades, radiotherapy has been had a fundamental role in the treatment of cancers. The tumor control probability (TCP) and lowest risk in normal tissue is the aim of radiotherapy techniques. The radiation sensitivity of thyroid glands increases cancer risk of scattering radiation and induces hypothyroidism. In this study, the average thyroid dose due to head and neck radiotherapy in t...
The meaning of probabilistic weather forecasts is discussed from the point of view of a subjectivist concept of probability. The prior degree of belief of probabilities of the weather in question, for a given forecast statement, is expressed analytically as a beta function. Bzyes’ theorem is used to modify this degree of belief in the light of experience, producing a posterior degree of belief ...
