摘要
A method and a system are provided for automatically delineating a striatum in a nuclear medicine brain image and calculating a striatum specific uptake ratio. In the method, initially, a target image is obtained. Then, the target image is projected to a space coordinate to generate a projection amount; an upper end and a lower end of a brain are obtained; and a preset range from the upper to the lower ends is set as a striatum slice area in the target image. A brain area is determined from the target image by a line detection method. Then, a brain volume template is deformed according to the brain area and the striatum slice area, so that a striatum in the brain volume template corresponds to the target image to delineate a striatum region of the target image. Finally, a specific uptake ratio of the striatum region can be calculated.
