In a method for dynamic computed tomography wherein, a contrast agent is injected into a patient, and a region of interest of the patient where the contrast agent is flowing is then scanned with a computed tomography machine, the computed tomography machine has a ray source and a ray detector. At least the ray source rotates relative to the region of interest of the patient. At a first rotational position of the ray source for a first rotation at a first time point a first image is obtained, and at said first rotational position for at least another rotation at a second time point a second image is obtained, the first and second images being different from one another in view of the flowing contrast agent. At least another rotational position of the ray source for the first rotation at a third time point a third image is obtained, and at the another rotational position for the another rotation at a fourth time point a fourth image is obtained, the third and fourth images being different from one another in view of the flowing contrast agent. A first time interpolation is performed for at least the first and second images at an intermediate time point between the first and second time points, and at least a second time interpolation is performed for the third and fourth images at an intermediate time point between the third and fourth time points. Using at least the first and second time interpolations, a reconstructed image is created.
