PROBLEM TO BE SOLVED: To provide a method improved for generating an image by a new method for generating a medical image, especially using a HYPR (Highly Constrained Backprojection) reconstruction method. SOLUTION: This image reconstruction method includes reconstructing a composite image of a subject using a conventional reconstruction method. An initial frame acquired from constrained data is used for generating normalized weighting image, and the normalized weighting image is multiplied by a high-quality composite image to generate a high-quality image frame. The normalized weighting image is acquired by smoothing the initial image frame using a filter and dividing the smoothed image frame by a similar smoothed version of the composite image. When the initial image frame is constrained by undersampling, the version of the composite image used for generating the normalized weighting image is "limited" to the same undersampled view imported in the initial image frame.
