Method for generating image files for medical computer tomography system

摘要

The method involves using a computer tomography system has a gantry (12) with an X-ray generator, which rotates about a patient (22). Projection data are acquired for at least two adjacent image sections by helically scanning the patient. The data are processed to produce image data. The image data are deconvoluted in a z-direction. The helical pitch is 0.5 beta / alpha , where beta is the thickness of the section and alpha is the size of a collimator opening. the deconvolution uses a core, whose value is at least 2.
