An optimized MRI RF coil for integration with in-bore therapy or biopsy system is discussed. The RF coil is optimally designed into an open Ω shape. Such that, the in-bore treatment system can have bigger space and more power. The optimized design also separated HIFU or SWL sub-assembly from high voltage RF parts, which reduces EMI between those two, and safety issue due to liquid leakage from HIFU or SWL sub-assembly is also greatly reduced.An upcoming trend is integration of therapeutic modality with diagnostic modalities. E.g., HIFU (high intensity focused ultrasound), SWL (shock wave lithotripsy) and laser treatment system is seen to be integrated with MRI. Figure 1 depicts a traditional MRI guided HIFU system. The HIFU module (6) is limited within a cradle area (5). The RF coil (2) is a round and placed inside a gradient coil (1). The cradle is supported by a bracket called bridge (3) and wheels (4). Conventional integrated systems face some challenges, including limited space for treatment or biopsy system, EMI and also tank leakage which is a fatal failure mode as the RF coil beneath the liquid tank is a high voltage part, as was shown in Figure 3. As an example, one conventional technique [1] includes a device for breast biopsy and/or therapy within MRI, which includes a structure for performing biopsy placed inside the magnet bore of the MRI apparatus. It would be desirable to have a technique to provide a large size biopsy or therapy system that can be integrated with MRI system and resolves issues of EM interaction and leakage of liquid tank in the integrated MRI system for therapy or biopsy. A technique including an optimized MRI RF body coil is disclosed. The technique includes an open shape body coil with an integrated bridge. Figure 2 depicts an example of an optimized MRI RF coil for integration with an in-bore therapy or biopsy system. As illustrated in Figure 2, the RF body coil (2) is optimally designed into an open Ω shape inside a gradient coil (1). Such design allows a much bigger room for the in-bore treatment system (6) for therapy or biopsy. The horizontal rails as well as coil support brackets (3) are integrated with body coil. A patient handling system, cradle (5) with wheels (4) is able to move on the rails (3) to transmit a patient, such that, the in-bore treatment system (6) can have bigger space, and consequently can have bigger power. The proposed design is also far from high voltage parts on RF body coil. As a result, less EMI exists in such design. Further, since gradient coil is in a whole piece, the gradient coil is thicker than the body coil without any cut in internal diameter; thereby safety issue due to liquid leakage is greatly reduced, as in Figure 4.The simulation results shows the RF coil can generate a homogenous B1 field in a Ω shape. Figure 5 depicts an example of multiple loops array body coil and Figure 6 depicts B1 field from the RF coil driven by a parallel transmit technology for quadrature mode excitation. Though B1 inhomogeneity is observed at a lower area in the body coil, there is HIFU and table at the lower area in the body coil. Therefore, B1 inhomogeneity is out of field of view. For mechanical feasibility, the design allows the RF body coil to be integrated with rails utilizing methods including, bonding a tube and CNC machined or extruded rails; extruding the rail and tube out at the same time; or additive manufacturing. As the RF coil design includes rails at top of the body coil mounting brackets, deformation of RF coil is minimized. Also, positioning is required between B1 field and patient cradle. Integration of the rails and RF body coil can fulfill the positioning requirement between the RF coil B1 field and the patient cradle, on which the treatment system positioning system is mounted.Figure 7 depicts a MRI system with this design, which solved the problems stated above. Further, the design improves cleanability of the liquid and consequently provides easy maintenance. The liquid can directly be wiped when cradle is outside bore. Figure 8 depicts the improved cleanability. However, as the shape of RF body coil is no longer a whole cylinder, vibration of the coil itself as well as the patient cradle might be a challenge. Further investigation is ongoing to address the potential issue.
