WitrynaIMRT is a technique where hundreds of small radiation beams with different intensities are delivered to provide precise tumour dose while minimising adjacent normal tissue doses and generate a conformal dose distribution with steep dose fall off at the boundary between tumour and normal structures. WitrynaIntensity-modulated radiation therapy, or IMRT, is a type of cancer treatment that uses advanced computer programs to calculate and deliver radiation directly to cancer cells from different angles. It allows people with cancer to receive higher, more effective doses of radiation while limiting damage to the healthy tissues and organs around it. florists in hatfield hertsWitrynaTechnika IMRT umożliwia dużo większą ochronę na-rządów krytycznych niż radioterapia konfromalna (CRT, conformal radiotherapy).
