摘要： An apparatus handles a series of medical images. A time density curve generation unit generates time density curves respectively corresponding to pixels from the series of medical images. An approximation processing unit approximates a convolution between a specific time density curve of the time density curves and each of types of kinetic models to each of the time density curves upon adjustment of at least one parameter which each of the kinetic models has. A suitability index map generation unit generates types of suitability index maps respectively corresponding to the types of kinetic models based on approximation errors respectively corresponding to the pixels, which are obtained by the approximation processing unit.
