Integrated multi-modality imaging system and method

Abstract

An integrated, multi-modality imaging technique is disclosed. The embodiment described combines a split-magnet MRI system with a digital x-ray system. The two systems are employed together to generate images of a subject in accordance with their individual physics and imaging characteristics. The images may be displaced in real time, such as during a surgical intervention. The images may be registered with one another and combined to form a composite image in which tissues or objects difficult to image in one modality are visible. By appropriately selecting the position of an x-ray source and detector, and by programming a desired corresponding slice for MRI imaging, useful combined images may be obtained and displayed.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to the field of imaging systems such as those used in medical diagnostics. More particularly, the invention relates to an integrated system that makes use of different modalities in a complementary fashion to permit feedback to surgeons and other medical professionals of physical conditions of a subject, particularly during interventionary procedures. BACKGROUND OF THE INVENTION [0002] A wide variety of imaging systems have been developed and are presently in use in the medical field. The systems may be generally categorized in a series of “modalities,” with each modality being characterized by its particular physics, control, utility, and so forth. For example, magnetic resonance imaging (MRI) systems are commonly employed for producing images of gyromagnetic material within a subject of interest. Over recent years, such systems have become particularly refined in producing high quality and reliable images of int...

Problems solved by technology

These contrast agents, however, do not necessarily provide the particular tissue identification desired, may not be retained for the time and in the locations desired for the entire procedure, and may cause complications for certain patients.

For example, during catheterization, angioplasty, and similar procedures, MRI systems may permit a surgeon to identify soft tissues through which a probe is inserted, but are not necessarily well suited to imaging tissues indicative of the actual location of the probe.

Because surgical interventions happen in real time, currently available technologies for separate modality imaging are simply ill suited to providing this type of information and feedback.
