Abstract

A medical imaging apparatus comprises magnetic resonance imaging means (30) for obtaining a MR tomogram of an object to be examined, X-ray radiographic means (11,12,13) for obtaining a radiographic image of the object and imaging control means for controlling overall timings of application of magnetic fields and acquisition of the nuclear magnetic resonance signals in the MRI means and timing of X-ray emission in the X-ray radiographic means. In the medical imaging apparatus, MR imaging is carried out in parallel with X-ray radiography by controlling the timing of X-ray emission to be noncoincident with both the timing of application of magnetic fields and the timing of acquisition of NMR signals to obtain X-ray images and MR images both having approximately the same time phase.
