A magnetic resonance imaging (MRI) radio frequency (RF) receive coil assembly is disclosed. The assembly comprises a deformable pad which comprises an array of tracking coils disposed on a surface of the deformable pad, each tracking coil corresponding to a grid point of the surface and configured to provide information of a position of the grid point. One or more RF receive coils are disposed within the deformable pad.

Systems and methods for tracking imaging attenuators

A system for imaging an object is provided including a first imaging acquisition module, a magnetic resonance imaging (MRI) acquisition module, and a first reconstruction module. The first imaging acquisition module is configured to acquire imaging information using a first non-MRI modality. The MRI acquisition module is configured to acquire MR non-imaging, foreign structure (NFIS) information. The MR NFIS information is acquired via at least one tracking coil associated with an external non-therapeutic (ENT) structure. The MR NIFS information corresponds to at least one of a position or orientation of the ENT structure. The first reconstruction module is configured to obtain the MR NIFS information and use the MR NIFS information to correct an attenuation in the imaging information acquired by the first imaging acquisition module associated with the ENT structure.

A method for producing an attenuation-corrected time-gated PET image comprising includes obtaining a baseline MR image and a cine MR image of a structure; registering the baseline MR image to the cine MR image to create an image transform; and generating a corresponding cine ACF matrix using the image transform, and time-correlating the ACF matrix to a time-gated PET data set to produce an attenuation-corrected time-gated PET image.

Method and apparatus for gate specific MR-based attenuation correction of timed-gated pet studies

A method for attenuation correction of a plurality of time-gated PET images of a moving structure includes establishing an ACF matrix, based on a baseline MR image of the structure; developing a plurality of image transforms, each of the image transforms registering the baseline MR image to a respective cine MR image of the moving structure; applying each of the image transforms to the ACF matrix to generate a corresponding cine ACF matrix; time-correlating each of the cine MR images, and its corresponding cine ACF matrix, to one of the plurality of time-gated PET data sets; and producing from each of the time-gated PET data sets an attenuation-corrected time-gated PET image.

Method and apparatus for gate specific MR-based attenuation correction of time-gated PET studies

A system for isolating vibration and reducing acoustic noise in the RF coil of an MR imaging apparatus is presented. The system positions an RF conductor in its operative position proximate to an RF support form. The RF conductor is sandwiched between a vibration decoupling layer and a mass loading layer. The vibration decoupling layer is affixed to the RF support form so that the vibration decoupling layer is positioned between the RF conduit and the RF support form while the mass loading layer is located exterior of the RF conductor. By this arrangement, the acoustic energy is decoupled from the RF support form by the vibration decoupling layer while the vibration is reduced by the mass loading layer located exterior of the RF conductor.
