Conditional Monte Carlo refers to sampling from the conditional distribution of a random vector X given value T ( ) = t for function . Classical methods were designed estimating expectations functions ϕ by unconditional distributions obtained certain weighting schemes. The basic ingredients use importance and change variables. In present paper we reformulate problem introducing an artificial pa...

Background: An effective method for management of large and bulky malignant tumors. This treatment modality is also known as Specially Fractionated Radiation Therapy (SFRT). In this treatment technique a grid block converted the open radiation field into a series of pencil beams. Dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and Mo...
