Abstract: A system receives, at a conference platform, a communication from a communications device of a requester requesting to host an audio conference. The system determines whether an access code provided by the requester is a valid access code associated with a provider communications address specified by the requester. A processor identifies a country from which the communication of the requester originated and determines whether the country from which the communication of the requester originated is a pre-authorized country, associated with a host account, from which to host the global audio conference. An audio conference is established when the access code specified by the requester is determined to be a valid access code associated with the provider communications address specified by the requester and when the country from which the communication of the requester originated is determined to be a pre-authorized country from which to host the audio conference.

Abstract: A collimator handling system for partially or fully automating the task of replacing and storing collimators in nuclear imaging systems. A collimator server stores a set of different collimators in stacked drawers which may be automatically extracted into the detector. The reduction in time spent on these tasks reduces cost and increases throughput. Furthermore, the automation of handling heavy lead (or like) collimators increases technician safety.

Abstract: An apparatus for operation with a nuclear camera of a nuclear medicine gantry and a patient handling system is provided and includes a cart assembly; and a collimator drawer assembly supported on the cart assembly. The collimator drawer assembly includes a housing; a plurality of collimator drawers slidably supported in housing, wherein each drawer is supported on a rail provided on opposed sides of said drawer; a damper operatively connected to each drawer; and a drawer locking mechanism movable from a first position in which all the drawers are prevented from sliding out of the housing and a second position in which all of the drawers are free to slide out of the housing. The collimator drawer assembly further includes an anti-tip over feature.

Abstract: An alignment system for use in connection with a patient handling system and a nuclear medicine gantry is provided. The alignment system includes a nuclear camera alignment fixture mountable to the nuclear detector. The nuclear camera alignment fixture includes a pair of lasers mounted in a known position relative to a center of the nuclear detector and oriented substantially toward the nuclear medicine gantry. The nuclear camera alignment fixture further includes a pair of laser targets provided on the nuclear medicine gantry. Each laser target has a fixed location with respect to an axis of rotation of the nuclear medicine gantry. The nuclear detector is moved relative to the nuclear medicine gantry until a laser beam from each laser hits a respective laser target. The alignment system is also capable of aligning the patient handling system with respect to the axis of rotation of the nuclear medicine gantry.

Abstract: The present invention relates to an apparatus for nuclear medicine imaging in which the imaging platform is attached directly to the detectors for nuclear imaging to allow for minimal constant distance between the detector(s) and the object to be imaged. As the detector moves around the object to be imaged to capture different angular views of the object, the imaging platform is rotated in a compensatory manner to maintain a its long axis perpendicular to gravity during movement of the detector. An advantage of this configuration over prior systems is the ability to obtain multiple angular projections while the distance between the detector and the object being imaged is maintained at a minimum, but the danger of detector-object collision is minimized and the necessity for orbital path calibration to preserve precision of detector movement and distance is eliminated.
