Abstract: A microfluidic chip device based on a magnetic field-controlled fluorescently labeled cell sorting method and a use method are disclosed. The microfluidic chip comprises a sample channel, two sheath fluid channels, a first fluorescence detection area, a second fluorescence detection area, a magnetic field control system, a magnetic field-controlled cell sorting area, a target cell channel, and a waste fluid channel. Based on fluorescence signals labeled on the cells, the FACS system is combined with a magnetic field-controlled sorting system to achieve automated cell sorting, which not only miniaturizes and automates the sorting detection integration, but also has the advantages of easy and economical operation. The device sorts both a large number of cell samples and a small number of cell samples, thus overcoming the defects of a flow cytometer.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry is configured to execute first calculation processing of calculating three-dimensional position information of each of an X-ray generator and an X-ray detector during rotation imaging, based on projection data acquired by executing the rotation imaging for a phantom with the X-ray generator and the X-ray detector arranged rotatably around the phantom.

Abstract: Devices and systems for droplet generation and methods for generating droplets are described. In an embodiment, the devices and systems include a capillary configured to eject a droplet, such as in response to a voltage applied to an end of the capillary. In an embodiment, the devices and systems include a moveable stage configured to carry a multi-well plate and move the stage relative to the capillary such that the ejected droplet is selectively received by a well of the multi-well plate carried by the moveable stage.
