Classification: CPC G | IPC G

Claim 0:
1. A system for reconstructing an image of an object, wherein the system comprises:
a memory; and
processor circuitry coupled to the memory, and configured to:
provide projection data of the object, wherein the projection data has been acquired by a computer tomography (CT) system;
generate a base image based on the projection data;
modify the base image to generate a modified image, wherein for modifying the base image the processor circuitry is configured to modify an image value of a voxel of the base image based on the image value of the voxel; and
reconstruct an image of the object based on the projection data using an iterative reconstruction algorithm that employs the modified image as a start image for an iterative reconstruction, wherein the projection data comprises scout scan projection data acquired during a scout scan of the object and diagnostic projection data acquired during a diagnostic scan of the object, wherein processor circuitry is configured to reconstruct the image of the object based on the scout scan projection data and the diagnostic scan projection data using the iterative reconstruction algorithm,
wherein during the iterative reconstruction the scout scan projection data receives a lower weight than the diagnostic projection data.
