Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.

Abstract: Magnetic resonance fingerprinting (“MRF”) techniques in which T1, T2, and T2* are simultaneously quantified using a combined gradient echo and spin echo acquisition with integrated B1 correction are described. The values for T2 and T2* can be estimated separately, but using the same underlying dictionary. This approach enables a smaller dictionary size that is easily manageable, and also reduced error propagation. Moreover, by using echo planar imaging (“EPI”) readouts, the raw MRF images will have higher signal-to-noise ratio (“SNR”) relative images acquired using spiral-based MRF techniques. The EPI-based images are also relatively free of artifacts. Together, these advantages lead to the need for far fewer frames, thereby enabling much faster acquisitions. Moreover, offline reconstruction is not needed, allowing for a more straightforward implementation of MRF.
