METHOD FOR UPDATING A MAGNETIC FIELD MAP DURING A MRI EXAMINATION
Proposed concepts thus aim to provide schemes, solutions, concept, designs, methods and systems pertaining to updating a magnetic field (B0) map of a subject during a magnetic resonance imaging (MRI) examination or during image reconstruction. In particular, when a subject moves, the magnetic field inside the magnetic bore changes. As a result, any B0 map obtained prior to the movement of the subject may be inaccurate. Accordingly, an initial B0 map is updated to reflect changes in the B0 map caused by the movement of the subject. This can be achieved by determining a B0 map of the subject based on a B0 prediction model, instead of spending additional scanning time to acquire another B0 map.

The method comprises receiving an instruction to transition from a first set of first video tracks VT1 to a second set of second video tracks VT2, obtaining the video tracks VT2 and, if the video tracks VT2 are different to the video tracks VT1, applying a lowering function to the rendering priority of one or more of the video tracks in the first set of video tracks VT1 and/or an increase function to the rendering priority of one or more video tracks in the second set of video tracks VT2. The lowering function and the increase function decrease and increase the rendering priority over time respectively. The rendering priority is used in the determination of the weighting of a video track and/or elements of a video track used to render a multi-track video.

Provided is an apparatus (100) for transporting sweat droplets (112) to a sensor. The apparatus comprises a chamber (102) for filling with sweat. The chamber has an inlet (104) lying adjacent the surface of the skin (106), which inlet permits sweat to enter and fill the chamber. The chamber has an outlet (114) from which a sweat droplet protrudes once the chamber has been filled. The apparatus further comprises a fluid transport assembly which is designed to enable the sweat droplet protruding from the outlet to become detached from the outlet of the chamber. The sweat droplet is subsequently transported by the fluid transport assembly to the sensor. Once the protruding droplet has been released from the outlet, the outlet is made available for a subsequent sweat droplet to protrude therefrom upon further filling of the chamber. The released sweat droplet is transported via the fluid transport assembly at least as fast as the subsequent sweat droplet protrudes from the outlet such that the respective sweat droplets do not contact each other before reaching the sensor. Thus, the apparatus supplies sweat to the sensor in a dropwise manner. Further provided is a system comprising the apparatus and a sensor, and a method for transporting sweat droplets to a sensor.
The invention concerns a computer-implemented method for controlling operation of an X-ray tube (100) with a high voltage generator (200) assembly for spectral imaging with an imaging system (300).

The method further comprises synchronizing (S620), based on the synchronization signal (SYNC), an X-ray tube kVp switching cycles with the detector integration periods, and synchronizing (S630), based on the synchronization signal (SYNC), control of an X-ray tube focal spot size and/or focal spot position with the detector integration periods. In an embodiment of the invention, the synchronization of the detector integration periods with the X-ray tube kVp switching cycles includes triggering control of a tube voltage (HV), and the synchronization of the detector integration periods with the X-ray tube focal spot size and/or focal spot position includes triggering control of a focusing current/voltage (FS).
Provided is a device (100) for expressing milk from a mammalian breast (102). The device comprises a nipple-enclosing wall (104) for interfacing with a nipple-comprising region (106) of the breast to define a chamber (108) between the nipple-enclosing wall and the nipple-comprising region of the breast in which an underpressure is providable. The chamber is, for example, connectable to an underpressure generator for decreasing a pressure in the chamber. The underpressure may assist milk to be expressed from the breast and/or may assist in retaining the interface between the nipple-enclosing wall and the nipple-comprising region. The device comprises an infrasound source (112) for producing infrasound. The infrasound souce comprises a moveable member (114) whose movement produces infrasound. The moveable member has a first side (114A) facing and in fluid communication with the chamber, and a second side (114B) opposite the first side. The second side is outside the chamber. A fluid connection (116) is provided between the chamber and the second side. The fluid connection may provide pressure equalization between the chamber and the second side of the moveable member so that both the first side and the second side of the moveable member experience the underpressure. The fluid connection is nonetheless configured to control fluid communication between the chamber and the second side of the moveable member during the movement of the moveable member and thus the fluid connection assists to control, e.g. enhance, a varying pressure experienced by the breast that is caused by the movement of the moveable member.
