In an X-ray computer tomograph (1) and a method for analyzing an object (2) by means of X-ray computer tomography, in order to improve the image quality a first intensity of the x-ray radiation (6) between an X-ray source (3) and the object (2) is measured by way of a first intensity measuring device (13), and a second intensity of the X-ray radiation (6) between the object (2) and an X-ray detector (4) outside of a projection region (10) of the object (2) is measured by way of a second intensity measuring device (15). A scattered radiation correction factor may be calculated for scattered radiation reduction by means of the intensities measured.
