Computer tomography apparatus with multiple x-ray radiation sources

A method of examining an object of interest, the method comprising:

• rotating a rotating radiation source around an object of interest;
• emitting radiation by the rotating radiation source to the object of interest while the rotating radiation source is rotating;
• emitting radiation by a non-rotating radiation source to the object of interest while the non-rotating radiation source is mounted non-rotatably relative to the object of interest;
• detecting radiation generated by the rotating radiation source and by the non-rotating radiation source that interact with the object of interest;
• determining structural information concerning the object of interest based on an analysis of the detected radiation.

A computer-readable medium, which carries instructions which, when being executed by a processor, controls the processor to carry out the steps of:

• emitting electromagnetic radiation by a first electromagnetic radiation source rotating around an object of interest;
• emitting electromagnetic radiation by a second electromagnetic radiation source non-rotatably disposed relative to the object of interest;
• detecting electromagnetic radiation generated by the rotating first electromagnetic radiation source and by the non-rotating second electromagnetic radiation source interacted with the object of interest;
• determining structural information concerning the object of interest based on an analysis of the detected electromagnetic radiation.

A program element of examining an object of interest, which, when being executed by a processor carries out the steps of:

• emitting electromagnetic radiation by a rotating electromagnetic radiation source which rotates around an object of interest;
• emitting electromagnetic radiation by a non-rotating electromagnetic radiation source which does not rotate around the object of interest;
• detecting electromagnetic radiation generated by rotating first electromagnetic radiation source and by the non-rotating electromagnetic radiation source and scattered on the object of interest;
• determining structural information concerning the object of interest based on an analysis of the detected electromagnetic radiation.

A computer tomography apparatus for examination of an object of interest, the computer tomography apparatus comprising:

• an object support;
• a rotatable gantry which rotates about the object support;
• a rotatable radiation source for irradiating the object and a rotatable radiation detector for detecting radiation mounted to the rotatable gantry for rotation therewith;
• a non-rotatable radiation source for irradiating the object mounted separate from the rotatable gantry.
