摘要： The present disclosure provides for effective systems and methods for increasing target tissue conspicuity within a particular anatomy of a particular patient. In an exemplary embodiment, a system associated with the present disclosure includes: (a) a MRI-guided HIFU system for generating ablation markings on a target tissue region, the MRI-guided HIFU system including a transducer for delivering HIFU to the target tissue region, the delivered HIFU generating the ablation markings on the target tissue and an MRI imaging system adapted to generate a three dimensional image of the target tissue region during HIFU delivery for guiding the delivery of the HIFU to the target tissue region; (b) a radiotherapy delivery system for delivering radiotherapy treatment to the target tissue region; and (c) a CT imaging system operable within the radiotherapy delivery system for generating a three dimensional image of the target tissue region. The markings generated on the target tissue region by the MRI-guided HIFU are visible in the image generated by the CT imaging system. The image generated by the CT imaging system guides the location of the radiotherapy treatment delivered to the target tissue region.

摘要： A system and method of dynamically allocating signal acquisition bandwidth in magnetic resonance imaging systems. The use of high spatial and high spectral resolution in MRI imaging can improve the clinical usefulness of the images. However, during uptake and washout of contrast agents, the use of high spatial and high spectral resolution results in important information being missed. Dynamic allocation of MRI signal acquisition bandwidth allows the use of high temporal resolution during contrast agent uptake and washout and high spatial and spectral resolution during periods of slower morphology resulting in images containing additional data than in conventional MRI protocols.
