摘要： A magnetic resonance scanner (12) is configured for thermographic imaging. One or more processors (28) receive (56) thermal image data from the magnetic resonance scanner and reconstruct at least one thermal image in which each voxel includes a measure of temperature change. The one or more processors identify (58) thermally abnormal voxels. A display (44) displays at least one reconstructed image with the identified abnormal thermal locations.

摘要： The exemplary embodiments are related to systems and methods for a mode balanced parametric amplifier. Exemplary embodiments relate to a balanced parametric circuit including a first resonant structure including a first plurality of varactor diodes and a second resonant structure including a second plurality of varactor diodes. The first and second resonant structures are coupled to form a coupled structure having at least two orthogonal resonant modes, where a first resonant mode is resonant at a first frequency of an input signal and a second resonant mode is resonant at a second frequency of a pump signal. Further, the pump signal is used to one of amplify the first signal at the first frequency or mix and amplify the first signal to a frequency higher than the first frequency.
