background: radiosurgery is a focal brain irradiation technique that delivers, usually in a single session, high dose of ionizing radiation. the presence of lateral electronic disequilibrium and steep dose gradients in small fields demands special attention to the selection of a suitable detector with respect to its size, composition and response. materials and methods : small circular fields w...

By introducing a variable transformation ?=12(sin?+1), complex-form ordinary differential equation (ODE) for the small symmetrical deformation of an elastic torus is successfully transformed into well-known Heun’s ODE, whose exact solution obtained in terms functions. To overcome computational difficulties ODE dealing with boundary conditions, real-form system proposed. A general code numerical...
