20150102812 | NMR REACTION MONITORING FLOW CELL - A monitoring cell, used to perform a measurement in an NMR spectrometer of a reaction fluid produced by a reaction vessel, has a body having inlet and outlet transport coaxial capillaries for transporting the reaction fluid between the body and the reaction vessel. Cooling lines are also positioned coaxially with the transport capillaries to transport cooling liquid between the body and the reaction vessel. The cell further has a hollow sample probe for insertion into the NMR spectrometer and a coupler section that removably connects the sample probe to the body so that the inlet transport capillary extends through the body into the interior of the sample probe and the outlet transport capillary is sealed to the sample probe to allow reaction fluid that enters the sample probe via the inlet transport capillary to exit the sample probe via the outlet transport capillary. | 04-16-2015 |
20150130463 | PORTABLE DEVICE FOR NMR BASED ANALYSIS OF RHEOLOGICAL CHANGES IN LIQUID SAMPLES - The invention features a portable device for monitoring changes in the rheological state of multiple samples by NMR based measurement. The rheological changes can be, for example, gelation occurring during limulus amoebocyte lysate (LAL) testing for endotoxins or blood coagulation. The inventive method entails organization of individual NMR tubes in a disposable cartridge where the tubes are connected through a top cover, provided with movable actuators to push the reagent in the reagent compartments of the individual chambers to the reaction chambers in a predetermined sequence. | 05-14-2015 |
20150323618 | Systems and Methods for Moving Magnetic Resonance Imaging - A magnetic resonance imaging (“MRI”) system that can be operated while a subject performs, experiences, or otherwise undergoes naturalistic motion. This movable MRI (“mMRI”) system includes a magnet whose position and orientation can be changed while the subject is moving, such that the magnet and subject maintain a substantially fixed spatial relationship relative to each other. | 11-12-2015 |
20150377987 | MAGNETIC RESONANCE SYSTEM AND METHOD TO DETECT AND CONFIRM ANALYTES - A system and method are provided to detect target analytes based on magnetic resonance measurements. Magnetic structures produce distinct magnetic field regions having a size comparable to the analyte. When the analyte is bound in those regions, magnetic resonance signals from the sample are changed, leading to detection of the analyte. | 12-31-2015 |
20160047867 | SAMPLE HOLDER AND METHOD - A sample holder for use with magic angle spinning NMR and similar magnetic resonance analysis techniques which includes a sample holder sealed by an O-ring and a contact seal. The O-ring seals the sample volume during pressurization whereas the contact seal is active during analysis. The O-ring and the contact seal are disposed so that rotation of a plug selective engages one or both of the seals. | 02-18-2016 |
20160077170 | MEDICAL IMAGING APPARATUS WITH A MOVABLY MOUNTED PATIENT BED - A medical imaging apparatus has a patient-receiving area, with a patient bed for supporting a patient and a sliding-support for movable mounting of the patient bed inside the patient-receiving area with the sliding-support has at least one first sliding-support element, which is arranged on the patient bed, and at least two second sliding-support elements, which are arranged inside the patient-receiving area and that engage a first sliding surface of the at least one first sliding-support element. The sliding-support further has at least one third sliding-support element that, when the patient bed is only partially inside the patient-receiving area, engages a second sliding surface of the at least one first sliding-support element. | 03-17-2016 |
20160077175 | MAGNETIC RESONANCE IMAGING APPARATUS - According to one embodiment, an MRI apparatus includes a bed, a digital processing circuit, a first antenna, first radio communication circuitry, a second antenna, second radio communication circuitry, and an image reconstruction circuit. An object is loaded on the bed. The digital processing circuit is disposed inside the bed, acquires analogue MR signals from an RF coil which receives MR signals emitted from the object, and digitizes the acquired MR signals. The first radio communication circuitry wirelessly transmits the MR signals digitized by the digital processing circuit, by using the first antenna. The second radio communication circuitry wirelessly receives the MR signals wirelessly transmitted from the first antenna, by using the second antenna. The image reconstruction circuit reconstructs image data based on the MR signals received by the second radio communication circuitry. | 03-17-2016 |
