Abstract
Systems and methods for obtaining simultaneous X-ray—magnetic resonance imaging (MRI) images are provided. A magnetic resonance X-ray CT (MRX) system can combine X-ray imaging and MRI in a cost-effective and relatively simple solution for improved imaging. During imaging of a subject, the X-ray source and X-ray detector can be simultaneously rotated around the subject, and the means for generating a magnetic field can also be rotated around the subject. The means for generating a magnetic field can be a plurality of permanent magnets.
Claims28
A system for performing simultaneous X-ray imaging and magnetic resonance imaging (MRI), the system comprising:
- an X-ray source;
- an X-ray detector for detecting X-rays from the X-ray source;
- a radio frequency (RF) coil;
- at least one gradient coil;
- and
- a magnetic field source for MR imaging, the magnetic field source comprising a first magnet ring and a second magnet ring disposed such that their radii are substantially parallel to each other, and a partial third magnet ring disposed between the first and second magnet rings in an axial direction substantially perpendicular to the radii of the first and second magnet rings such that the partial third magnet ring is not concentric to either of the first magnet ring and the second magnet ring;
- wherein the system is configured such that, during imaging of a subject:
- the X-ray source and X-ray detector are simultaneously rotated around the subject;
- and
- the magnetic field source is rotated around the subject.
A method for performing simultaneous X-ray imaging and magnetic resonance imaging (MRI), the method comprising:
- providing a subject to be imaged;
- and using the system of claim of 1 to perform simultaneous X-ray imaging and MRI on the subject.
