Abstract: A magnetic resonance imaging apparatus according to an aspect of the present disclosure includes a sequence controlling circuit and a processing circuit. The sequence controlling circuit is configured to acquire undersampled frequency domain scan data by executing a pulse sequence while carrying out an undersampling process. The processing circuit is configured: to generate image domain corrected data of the frequency domain scan data, by correcting the frequency domain scan data in an image domain; to generate frequency domain corrected data of the frequency domain scan data by correcting the frequency domain scan data in a frequency domain; to optimize the frequency domain scan data based on the image domain corrected data and the frequency domain corrected data; and to reconstruct image data by using the optimized frequency domain scan data.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a processing circuitry configured to generate a pulse sequence including a plurality of repetition times (TRs) each of which includes an echo train and a driven equilibrium pulse applied following the echo train, vary a flip angle of the driven equilibrium pulse, obtain magnetic resonance image data collected by executing the pulse sequence, and reconstruct a magnetic resonance image by using the magnetic resonance image data.

Abstract: Diagnostic systems, methods, and devices employing low-cost handheld components are disclosed herein. A diagnostic system can include a diagnostic device that is configured to perform one or more assays on a fluid sample, such as a whole blood sample, in one or more microfluidic channels or chambers. The diagnostic device can move the fluid sample into or through the one or more microfluidic channels or chambers without using any electrical power, for example, using manual actuation to generate a positive or negative pressure within the diagnostic device. The diagnostic device can have a connector for interfacing with a separate handheld unit that can provide power and data processing. For example, the separate handheld unit can be a smartphone or PDA, and the connector can interface with an existing input/output port of the unit to draw power and/or transmit data.
