Patent number: 11844600Abstract: A patient table adapted for use in association with an MR scanner for neonatal infants is provided. The patient table has an extendable patient bed attached to and extendable from the patient table. The patient bed may be at least partially inserted into an MR scanner without requiring the patient table to enter the MR scanner. A transport mechanism is on the underside of the patient table so that it may be readily moved over the floor on which it rests. The patient table includes a latching mechanism that may operate to releasably attach the patient table to a patient table docking assembly. The docking assembly is operative to selectively move the patient table towards, into and away from the MR scanner.Type: GrantFiled: May 17, 2021Date of Patent: December 19, 2023Assignee: CHILDREN'S HOSPITAL MEDICAL CENTERInventor: Charles L Dumoulin

Patent number: 9846207Abstract: An RF coil assembly for use in a Magnetic Resonance Imaging scanner incorporates sound absorbing material in its construction for the purpose of attenuating the sound perceived by a patient lying inside the RF coil. Unlike a conventional RF coil assembly in which rigid components are used to support the coil within the magnet bore, the quiet RF coil assembly is constructed without rigid support components. In one embodiment, open cell foam may be used to support the RF coil components and the entire assembly is wrapped in a. flexible cloth-like material.Type: GrantFiled: December 21, 2012Date of Patent: December 19, 2017Assignee: CHILDREN'S HOSPITAL MEDICAL CENTERInventors: Charles L. Dumoulin, Randy Giaquinto, Wolfgang Loew

Patent number: 9625545Abstract: A Faraday cage assembly for use with a Magnetic Resonance (MR) Imaging scanner is deployed inside the MR scanner room. The Faraday cage assembly is configured to accept accessory medical equipment which is desired to be attached to the patient during scanning. Accessory medical equipment can include patient monitoring systems, injector pumps, and intravenous (IV) poles with infusion pumps. Once the accessory medical equipment is placed inside the Faraday cage, radiofrequency (RF) interference emitted by the accessory medical equipment is contained within the cage and cannot significantly degrade MR image quality. The cage may permit non-MR compatible accessory equipment such as infusion pumps to be used without modification or reconfiguration during MR scanning.Type: GrantFiled: April 28, 2014Date of Patent: April 18, 2017Assignee: Childrens Hospital Medical CenterInventors: Charles L. Dumoulin, Ronald Pratt

Patent number: 9396561Abstract: A framework is provided for accelerating multi-scan and multi-channel data acquisition in a clinical MRI protocol by estimating correlation functions from images previously acquired or reconstructed, with the same or with different contrast and resolution. Using an MRI apparatus, the method collects a plurality of prior MRI image scan data sets, obtains a current MRI scan data, and reconstructs the current MRI scan data set using an aggregate of the plurality of prior MRI image data sets. The method provided may optimize previously acquired MRI image data sets to reconstruct an MRI image scan data set and image.Type: GrantFiled: January 4, 2013Date of Patent: July 19, 2016Assignee: Children's Hospital Medical CenterInventors: Charles L. Dumoulin, Yu Li

Publication number: 20150338477Abstract: A composite system for use in conjunction with an MR-imaging procedure. One composite system includes a fully-metallic filament, such as a needle or guide-wire, equipped with flat MR RF-receiver microcoil disposed such that a normal to the coil's plane is substantially transverse to the filament's axis. The microcoil is electrically connected to external device to register change of position and orientation of the tip during the navigation of the filament. Alternative composite system includes a filament made from different materials. The very tip includes diamagnetic and non-metallic tube tightly fit around geometrically-modified portion of the main body and carries at least one microcoil electrically connected to external device to register change of position and orientation of the tip during the filament navigation. Data representing co-registration of the position and/or orientation of filament is fed back to the system to improve navigation accuracy and precision.Type: ApplicationFiled: January 8, 2014Publication date: November 26, 2015Inventors: Ehud J.
