A magnetic resonance imaging system for interventional MR imaging involves operations to insert a device such as a catheter into an object. According to the system, a tip position of the catheter is detected, data indicative of moved loci of the catheter are produced from data indicative of the detected tip position, and the produced movement locus data are displayed. In addition, even when an operator changes the progress direction of the device such as a puncture needle, an imaging cross-section automatically tracks movements of the device. Appropriate preoperative planning is also provided.

A method includes, in a bi-plane interventional imaging system, moving a first C-arm supporting a first X-ray source and a first X-ray detector about first and second axes while obtaining a plurality of first X-ray attenuation data sets relating to a subject of interest; moving a second C-arm, positioned crosswise with respect to the first C-arm and supporting a second X-ray source and a second X-ray detector, about the first axis while obtaining a plurality of second X-ray attenuation data sets relating to the subject of interest; and synchronizing the movement of the first and second C-arms to avoid collision therebetween.

A multimodality imaging system including ultrasound, optical coherence tomography (OCT), photoacoustic (PA) imaging, florescence imaging and endoscopic catheter for imaging inside the gastrointestinal tract with real-time automatic image co-registration capability, including: an ultrasound subsystem for imaging; an optical coherence tomography (OCT) subsystem for imaging, a PA microscopy or tomography subsystem for imaging and a florescence imaging subsystem for imaging. An invasive interventional imaging device is included with an instrumentality to take a tissue biopsy from a location visible on the ultrasound subsystem for imaging, on the optical coherence tomography (OCT) subsystem for imaging, photoacoustic (PA) subsystem for imaging and florescence subsystem for imaging. The instrumentality takes a tissue biopsy from a visible location simultaneously with the visualization of the tissue about to be biopsied so that the tissue biopsy location is visualized before, during and after the biopsy.

A method for imaging a target region in a subject is presented. The method includes selecting one or more tomographic angle sequences, acquiring one or more image sequences corresponding to the one or more tomographic angle sequences, where each image sequence has a corresponding tomographic angle sequence, deriving geometric information corresponding to one or more structures of interest in at least one of the image sequences, identifying visualization information, generating one or more displacement maps based on the geometric information, the visualization information, at least a subset of at least one of the one or more tomographic angle sequences, or combinations thereof, transforming at least a subset of images in the one or more image sequences based on corresponding displacement maps to create one or more transformed / stabilized image sequences, and visualizing on a display the one or more transformed / stabilized image sequences to provide a stabilized presentation of the target region.

An embodiment of the present invention provides an interventional imaging system, including a light source unit, a beam shaping unit, a visible light-terahertz imaging fiber bundle, and an imaging unit. The annular terahertz wave is transmitted through the annular terahertz imaging fiber bundle in the visible light-terahertz imaging fiber bundle, the visible light is transmitted through the visible light imaging fiber bundle, and finally the visible light reflected by the imaging target and the annular terahertz wave are respectively transmitted through the imaging unit. Terahertz waves are received and imaged based on the received visible light and ring-shaped terahertz waves. It can safely and harmlessly realize the joint synchronous imaging of interventional visible light and terahertz waves, and obtain the results of visible light imaging and terahertz imaging simultaneously. By comparing terahertz images with visible light images, the contrast, readability and accuracy of in vivo interventional imaging results are further improved.
