Patent number: 9408554Abstract: A mobile medical imaging device that allows for multiple support structures, such as a tabletop or a seat, to be attached, and in which the imaging gantry is indexed to the patient by translating up and down the patient axis. In one embodiment, the imaging gantry can translate, rotate and/or tilt with respect to a support base, enabling imaging in multiple orientations, and can also rotate in-line with the support base to facilitate easy transport and/or storage of the device. The imaging device can be used in, for example, x-ray computed tomography (CT) and/or magnetic resonance imaging (MRI) applications.Type: GrantFiled: January 27, 2012Date of Patent: August 9, 2016Assignee: MOBIUS IMAGING, LLCInventor: Eugene A.

Publication number: 20160128656Abstract: A drive mechanism for a mobile imaging system comprises a main drive geared into a drive wheel for propelling the imaging system, including a base and one or more imaging components, across a surface. The drive mechanism can also include a scan drive that moves the drive mechanism and the one or more imaging components along an axis relative to the base to provide an imaging scan, and a suspension drive that extends the drive wheel relative to a bottom surface when the imaging system is in a transport mode and retracts the drive wheel relative to the bottom surface of the base when the imaging system is in an imaging mode. The drive wheel supports the weight of the imaging components, but does not directly support the base assembly, which can include pedestal and tabletop support. One or more casters located on the base can support the weight of the base assembly.Type: ApplicationFiled: November 9, 2015Publication date: May 12, 2016Inventors: Eugene A.

Publication number: 20150374322Abstract: A detector system for an imaging system includes an airflow cooling system. The detector system includes a detector chassis, a duct extending along the length of the chassis, and a manifold that couples the duct to the interior of the chassis. A vacuum source, such as a suction fan, is coupled to the duct and generates a vacuum force within the duct. The chassis includes a plurality of inlet openings, with an airflow path being defined through the interior of the chassis between the inlet openings and the manifold. The suction fan pulls cooling air through the inlet openings, through the chassis and manifold to the duct, and then expels the air through an exhaust opening. The airflow is directed into thermal contact with detector elements and associated electronics in the detector chassis to provide cooling of these components.Type: ApplicationFiled: September 8, 2015Publication date: December 31, 2015Inventors: Eugene A.

Patent number: 8746973Abstract: Systems and methods for obtaining two-dimensional images of an object, such as a patient, in multiple projection planes. In one aspect, the invention advantageously permits quasi-simultaneous image acquisition from multiple projection planes using a single radiation source. An imaging apparatus comprises a gantry having a central opening for positioning an object to be imaged, a source of radiation that is rotatable around the interior of the gantry ring and which is adapted to project radiation onto said object from a plurality of different projection angles; and a detector system adapted to detect the radiation at each projection angle to acquire object images from multiple projection planes in a quasi-simultaneous manner. The gantry can be a substantially “O-shaped” ring, with the source rotatable 360 degrees around the interior of the ring. The source can be an x-ray source, and the imaging apparatus can be used for medical x-ray imaging.Type: GrantFiled: December 14, 2006Date of Patent: June 10, 2014Assignee: Medtronic Navigation, Inc.Inventors: Eugene A.

Publication number: 20140139215Abstract: An imaging system and methods including a gantry defining a bore and an imaging axis extending through the bore, and at least one support member that supports the gantry such that the imaging axis has a generally vertical orientation, where the gantry is displaceable with respect to the at least one support member in a generally vertical direction. The imaging system may be configured to obtain a vertical imaging scan (e.g., a helical x-ray CT scan), of a patient in a weight-bearing position. The gantry may be rotatable between a first position, in which the gantry is supported such that the imaging axis has a generally vertical orientation, and a second position, such that the imaging axis has a generally horizontal orientation. The gantry may be displaceable in a horizontal direction and the system may perform a horizontal scan of a patient or object positioned within the bore.Type: ApplicationFiled: June 13, 2013Publication date: May 22, 2014Applicant: MOBIUS IMAGING, LLCInventors: Eugene A.
