Objective To recalculate biological effective dose values (BED) for radio-surgical treatments of acoustic neuroma from a previous study. BEDs values were previously overestimated by only using beam-on times in calculations, so excluding the important

Re-treatment, using megavoltage photon radiotherapy, can benefit carefully selected patients with new or recurrent tumours. Such re-treatments may involve the further exposure of tissues such as the brain or spinal cord. A time-dependent model has be

Objective How variations of treatment time affect the safety and efficacy of Gamma Knife (GK) radiosurgery is a matter of considerable debate. With the relative simplicity of treatment planning for trigeminal neuralgia (TN), this question has been ad

Purpose: To investigate the influence of changes in α/β ratio (range 1.5-3 Gy) on iso-effective doses, with varying treatment time, in spinal cord and central nervous system tissues with comparable radio-sensitivity. It is important to establish if
