Definitive radiochemotherapy is the standard treatment for many patients with locally advanced nonsmall cell lung cancer (NSCLC). Treatment outcomes have improved over the last decades. Several treatment regimens have been shown effective and safe. This review summarises the results of significant studies between 1996 and 2015 on concomitant and sequential radiochemotherapy regimens and radiati...

A triple-variable Integral Equation for Tumor Control Cumulative Probability (TCCP) is developed with the addition of important radiotherapy Treatment-Time parameter. Based on a previous double TCCP depending Biological Model parameters (α , β ), NEffective model implemented in (TCP) equation. Results comprise three essential Radiation Therapy precise determination TCCP. Solution shows method t...

The use of image-guidance in surgery and radiotherapy has significantly improved patient outcome in neurosurgery and radiotherapy treatments. This work developed volume definition and verification techniques for image-guided applications, using a number of algorithms ranging from image processing to visualization. Stereoscopic visualization, volumetric tumor model overlaid on an ultrasound imag...

Introduction: Today different uses of multileaf collimators(MLC) in different techniques of radiotherapy are common. Due to the use of this facility it is possible to have maximum radiation dose to target volumes and minimum radiation dose to critical tissues surronding treatment volumes. But there are numerouse Linear accelerators in IRAN without MLC. Because of high price of...
