A computing device for diffusion dictionary imaging (DDI) of microstructure and inflammation of a patient is provided. The DDI computing device is connected to other computing devices, such as a magnetic resonance imaging (MRI) scanner. The DDI computing device receives magnetic resonance (MR) signals from the MRI scanner. Once received, the DDI computing device records the one or more MR signals to a memory device. The DDI computing device computationally processes the one or more MR signals to reconstruct a diffusion MRI image using diffusion dictionary data. The MR signals include values that are used as input to algorithms of the DDI data to reconstruct the diffusion MRI image. A database is used to store DDI data, artificial intelligence (AI) data, diffusion dictionary data, and MR data.

A system includes a fixture, a laser assembly, and a positioning assembly. The fixture is configured to hold (i) a substrate of a distal-end assembly of a catheter and (ii) a lead placed on a given solder pad disposed on the substrate, the laser assembly is configured to emit a laser beam, and the positioning assembly is configured to move the fixture, with the substrate and the lead, relative to the laser assembly, so as to mark a soldering position, at which the lead is to be attached to the given solder pad, with a laser spot of the laser beam.

In a method and system, a medical imaging modality and the parameters to be deployed for the determined imaging modality are determined to produce an image of an examination object using the determined imaging modality and the determined parameters. Information from the preliminary examination(s) of the examination object can be automatically classified to generate classification results corresponding to interfering influence(s) resulting from the production of the image. The classification results can be analyzed to evaluate the classification results. The medical imaging modality and the parameter(s) is determined, based on the evaluated results, to minimize an influence of the interfering influences of the classification results in image(s) of the examination object generated using the determined medical imaging modality and the determined one or more parameters. The image(s) may then be generated using the determined medical imaging modality and the determined parameter(s).

Switching systems are positioned along a bidirectional signal carrying line, typically between an electrode in a catheter at the heart of a patient, and an external console. The switching system provides for switching the bidirectional signal carrying line between: a main line, which carries acquired electrocardiac signals from the electrode of the catheter at the heart of the patent to the external console, via a switch unit; and, a bypass line, which carries pacing signals, directly from the external console to the electrode of the catheter. The bypass line provides an uninterrupted electrical connection between the electrode and the external console, thus avoiding the switch unit.

A system provides ECG monitoring for a user. The system includes an in-ear device and processor. The in-ear device includes in-ear electrodes that capture electrical signals of the pulses of the heartbeat of the user from within the user's ear canal, and an out-of-ear electrode that does not contact any surface of the user's ear or ear canal, and captures electrical signals of pulses of the heartbeat of the user from a fingertip of the user when the user contacts the out-of-ear electrode with their fingertip. The processor generates ECG data using captured electrical signals responsive to a determination that the user has positioned a finger to touch the out-of-ear electrode on the in-ear device. This configuration allows the out-of-ear electrode to, when touched by the user's fingertip, effectively function as an arm electrode, allowing for ECG data to be measured from two different angles, through a path that passes through the user's heart.
