Abstract: This disclosure relates generally to treatment management systems, which may include a clinical database for storing therapeutic protocols. The system may also include a treatment engine operatively connected to the clinical database. The treatment engine may obtain diagnostic information and select a first plurality of therapeutic protocols from the clinical database based on the obtained diagnostic information and reference protocol data. The treatment engine may calculate a treatment efficacy probability for each protocol using the reference protocol data. The treatment engine may develop a first treatment plan and evaluate intermediate data indicating an altered patient state due to the first treatment plan. The treatment engine may select, based on reference protocol data and adaptive protocol data, a second treatment plan using a second plurality of therapeutic protocols.

Abstract: A magnetic resonance (MR) imaging system (100) including a housing (102) having first and second openings (110, 116), and first and second solenoid coils (160, 150), the first and second solenoid coils (160, 150) generate a magnetic field suitable for imaging within a region of interest (ROI). The first and second solenoid coils (160, 150) have a common longitudinal axis (LA). The first and second openings (110, 116) are situated on opposite sides of the housing (102) along the longitudinal axis (LA). The first solenoid coil (160) has a different inside diameter than the second solenoid coil (150) and is positioned adjacent the first opening (110). The second solenoid coil (150) is positioned adjacent the second opening (116). Accordingly, the system provides improved access to the patent during imaging, e.g. for MR guided interventional procedures.

Abstract: An apparatus includes an electrically conductive coil which produces a magnetic field when an electrical current passes therethrough; a selectively activated persistent current switch connected across the electrically conductive coil; a cryostat having the electrically conductive coil and the persistent current switch disposed therein; an energy dump; at least one sensor which detects an operating parameter of the apparatus and outputs at least one sensor signal in response thereto; and a magnet controller. The magnet controller receives the sensor signal(s) and in response thereto detects whether an operating fault (e.g. a power loss to the compressor of a cryocooler) exists in the apparatus, and when an operating fault is detected, connects the energy dump unit across the electrically conductive coil to transfer energy from the electrically conductive coil to the energy dump unit. The energy dump unit disperses the energy outside of the cryostat.

Abstract: A magnetic resonance examination system includes a main magnet with superconducting coils to generate a main magnetic field and a gradient system to apply a gradient magnetic field superposed on the main magnetic field. A cooling system cools the superconducting coils to below their critical superconductivity temperature. A transfer monitor assesses the transfer of energy from the gradient system to the cooling system. The transfer monitor is configured to measure pressure changes in the cooling system. This leads to a simple manner of evaluating the transfer of energy from the gradient coils into the cooling system.
