    摘要: The present disclosure is directed to a new technique for MR measurement of ultrashort T2* relaxation utilizing spin-echo acquisition. The ultrashort T2* relaxometry can be used for the quantification of highly concentrated iron labeled cells in cell trafficking and therapy. In an exemplary embodiment, a signal is induced by a low flip angle RF pulse. Following excitation pulse, a gradient readout is applied to form an echo. The time between the RF pulse and the center of the gradient readout is defined as TE. In tissues with highly concentrated iron labeled cells, T2* could be below 1 millisecond. Therefore, the signal can be decayed to a noise level with an echo time of a couple milliseconds. Because T2 is much longer in SPIO labeled cells, the signal acquired by spin echo is much bigger than that from the gradient echo, thus avoiding the negative effects associated with the massive signal loss in the image. The ultrashort T2* relaxation map can then by overlaid on the regular T2* map to generate the final T2* map of the field of view.

    摘要: A system may create work units, each work unit including at least one of an input port or output port, each work unit configured to modify data that is received via the input port. In addition, the system may compose a workflow by connecting an output port of a first of the work units to an input port of a second of the work units, receive a work order, select the workflow in response to the work order, decompose the workflow into constituent work units, instantiate tasks that correspond to the constituent work units, and execute a work unit process for each of the tasks.

    摘要: An electrical heating coal material decomposition apparatus includes a closed kiln body with a feed inlet, a discharge outlet, and an electrical heating device arranged in the kiln body. A propulsion and decomposition path of coal material is formed between the electrical heating device and the inner wall of the kiln body. A coal decomposition gas collecting pipe communicates with the propulsion and decomposition path of coal material, and is connected with a gas dust-trapping and liquefying device arranged outside the kiln. The electrical heating device transfers heat to the pulverized coal inside the propulsion and decomposition path of coal material by conduction and irradiation. The pulverized coal absorbs sufficient heat and decomposes into fuel gas, tar gas and coal. The fuel gas and tar gas enters the gas dust-trapping and liquefying mechanism through the decomposed gas collecting tube, where they are collected, dust-trapped, separated and liquefied under pressure.
