Abstract
An embodiment provides a medical image processing apparatus that comprises circuitry. The circuitry obtains detection data representing detection events of radiation at a plurality of detector elements. The circuitry reconstructs an image by iteratively using an optimization-transfer algorithm to the detection data. The optimization-transfer algorithm uses a quadratic surrogate function that includes a curvature. The curvature is calculated using an inverse-background image.
