Abstract: The present disclosure relates to a 1D partial Fourier parallel magnetic resonance imaging method with a deep convolutional network and belongs to the technical field of magnetic resonance imaging. The method includes steps of: creating a sample set and a sample label set for training; constructing an initial deep convolutional network model; inputting a training sample of the sample set to the initial deep convolutional network model for forward process, comparing an output result of the forward process with an expected result in the sample label set, and performing training with a gradient descent method until a parameter of each layer which enables consistency between the output result and the expected result to be maximum is obtained; creating an optimal deep convolutional network model by using the obtained parameter of the each layer; and inputting a multi-coil undersampled image sampled online to the optimal deep convolutional network model, performing the forward process on the optimal deep convolutional network model, and outputting a reconstructed single-channel full-sampled image. The present disclosure can well remove the noise of the reconstructed image, reconstruct a magnetic resonance image with a better visual effect, and has high practical value.

Abstract: A microfluidic system, including: a container, an ultrasound transmitter assembly, and a phononic crystal plate. The container is configured to accommodate a solution containing microparticles. The ultrasound transmitter assembly is configured to transmit ultrasonic waves to the phononic crystal plate, where the ultrasonic waves have a frequency which is the same as a resonance frequency of the phononic crystal plate. The phononic crystal plate is placed in the solution, and configured to generate a local acoustic field on a surface of the phononic crystal plate under excitation of the ultrasonic waves, and induce an acoustic microstreaming vortex to generate an acoustic streaming shear stress on the microparticles. The phononic crystal plate defines therein cavities, the respective cavities are arranged periodically in the phononic crystal plate, and all the respective cavities are filled with gas.

Abstract: A method for measuring pH includes using amide protons as an endogenous contrast agent, measuring a chemical exchange saturation transfer effect ratio R of amide protons corresponding to a pH-known amide proton solution under different saturation powers, then establishing a function relation between pH and R according to different pH-known amide proton solutions and the corresponding measured R thereto, and finally calculating the desired pH according to experimentally measured Ri and the function relation. The method can eliminate the impact of concentration and does not require any estimation or measurement of the parameters such as the concentration of exchangeable protons, the longitudinal relaxation time of water, etc., and therefore can measure pH more accurately, conveniently and non-invasively.

Abstract: A three-degree-of-freedom parallel mechanism with curved sliding pairs includes a fixed platform, a moving platform, and three curved branches disposed between the fixed platform and the moving platform. Each of the curved branches includes a first curved link and a second curved link that share a common arc center. One end of the first curved link is connected to fixed platform by a rotational pair. One end of the second curved link is disposed in a cavity at another end of the first curved link. The second curved link is operative to perform a reciprocating motion along a tangent of an arc of the first curved link. Another end of the second curved link is connected to the moving platform by a ball joint. The axes of the three rotational pairs of the three curved branches coincide with each other and are perpendicular to the fixed platform. In the three-degree-of-freedom parallel mechanism with curved sliding pairs, the moving platform of the parallel mechanism is rotatable around the X-axis, Y-axis, and Z-axis of a three-dimensional coordinate system taking the arc center of the three curved branches as the origin, where the rotation of the moving platform about the Z axis is decoupled from the rotation in the other two orientations.
