Latest Patents

Joseph O Deasy holds a patent for a "Method and apparatus for radiotherapy treatment planning." This invention presents a computationally efficient and accurate procedure for calculating radiation dose distributions within a volume of interest in a patient. It incorporates variations in patient density and source particle energy, position, direction, and type. The procedure iteratively simulates energy depositions from source particles using the Monte Carlo radiation transport method. It also applies methods for reducing noise inherent in Monte Carlo results to obtain an accurate representation of an actual radiation dose distribution compared to that produced by Monte Carlo methods alone. The invention makes an analogy between real measured data and transformed Monte Carlo generated computer data, applying data denoising techniques to reduce noise in the Monte Carlo dose images. Additionally, it can produce a dose distribution with a predetermined noise level in a reduced amount of computation time. Denoising techniques can include digital filtering, wavelet denoising, kernel smoothing, and non-parametric regression smoothing.
