Abstract
A real-time imaging and visualization method and system that allows multiple field-of-view imaging on multiple receiver channels is disclosed. The method and system implement a semi-bit reversed modified phase-encoding scheme to acquire identical data over all receiver channels, and to reconstruct independently on each channel an image thereby providing multiple FOV images. The method and system provide for real-time catheter tracking where separate receiver channels collect anatomical roadmap data, guidewire data, and catheter data. The present invention uses a loopless antenna to acquire projection images thereby allowing the entire antenna and structures within its diameter of sensitivity to appear as a bright signal and a long narrow connected region. The present invention allows for very narrow FOV imaging for guidewire and catheter channels as well as full FOV imaging for roadmap image reconstruction. Thus, multiple FOV images are displayed together, improving visualization of the interventional device placement.
