A resonance imaging (MRI) apparatus (10), comprising: one or more transmitting coils (12) for generating a static magnetic field within which a subject (14) can be positioned and a probe (16) for insertion into, and movement through, the subject (14). The probe (16) includes a tracking element (26,28) in the form of two loop coils and an imaging coil (24). Processing means (22) are provided for receiving spatially encoded signals from the loop coils (26,28) and from the imaging coil (24). The tracking signals from the loop coils (26,28) are decoded to determine the relative position of the probe (16) within an image volume and the image to be displayed as adjusted accordingly corresponding to the relative position of the probe (16). The image signals from the imaging coil (24) are also decoded to generate an image for display, and the image to be displayed is updated dynamically as the probe (16) is moved within the subject (14) based on successive sets of tracking signals received from the tracking element (26,38) and successive sets of spatially encoded signals received from the imaging coil (24).
Magnetic resonance imaging (MRI) apparatus, comprising:
An image processing module for a magnetic resonance imaging (MRI) system comprising one or more transmitting coils for generating a static magnetic field within which a subject can be positioned, an imaging coil and a probe for insertion into, and movement through, said subject, said probe including a tracking element, the image processing module being arranged and configured to receive spatially encoded image signals from said imaging coil and tracking signals from said tracking element, decode said signals from said tracking element to determine the relative position of the probe within an image volume and adjust the image to be displayed accordingly corresponding to said relative position of the probe, decode the signals from said imaging coil to generate an image for display, and update said image to be displayed dynamically as said probe is moved through said subject based on tracking and spatially encoded signals received from said tracking element and said imaging coil respectively.
A method of generating an image for display of an image slice or volume within a subject using a magnetic resonance imaging (MRI) system comprising an imaging coil, the method comprising positioning a subject within a static magnetic field, spatially encoding said magnetic field, moving a probe through said subject, said probe including a tracking element, and collecting tracking signals from said tracking element provided in or on said probe and spatially encoded signals from said imaging coil, decoding said signals received from said tracking element, determining the relative location within an image volume of said probe using said signals collected from said tracking element and adjusting the image to be displayed accordingly corresponding said relative position of the probe, decoding said spatially encoded signals from said imaging coil to generate an image for display, and updating said image to be displayed dynamically as said probe is moved through said subject based on tracking and spatially encoded signals received from said tracking element and said imaging coil respectively.
