The primary goal of radiotherapy is to deliver maximum dose to tumor but minimal dose to normal tissues.Irregular surfaces along with cavities sometimes make it difficult to deliver a homogenous radiation dose.Data royal nomadic 5413 rug incorporated in the delivery of prescribed dose are measured from the dosimetric system which are homogenous in nature, hence the exposed medium (i.e.tumor) should posses the same property in constituents and nature.

At the inference of two different mediums, such as in case of cavity in the treatment field; there occurs build up and build down effects in dose delivery that may result into hot spot and cold spot.These cold spot may result acupatch in recurrences.The aim of this paper is to fabricate a simple, cost effective tissue bolus device, which may be filled with normal saline to reproduce homogenous and regular medium at the time of radiotherapy.
