Abstract: A piece of equipment that needs services may not have connectivity to a network. In an example method, an event triggers the piece of equipment to generate a barcode or QR code. The event may be installation of equipment, preventive maintenance, update of software, periodic calibration, abnormal operation, change of location, etc. The barcode or QR code contains information of the piece of equipment and the triggering event. The piece of equipment halts upon display of the barcode or QR code. An application installed in a user device scans the barcode or QR code and sends a message to a remote service center. The service center analyzes the message and updates a service database. The service center returns a key in a message back to the user device. When the key is input into the piece of equipment, the operation of the piece of equipment is resumed.

Abstract: Methods and systems are provided for calibrating a nuclear medicine imaging system. In one embodiment, a method comprises: detecting, with a plurality of detectors, photons emitted by a calibration source comprising a radioactive line source and a fluorescence source, while pivoting one or more detectors of the plurality of detectors; and calibrating, with a processor communicatively coupled to the plurality of detectors, each detector of the plurality of detectors based on energy measurements of the detected photons. In this way, a two-point energy calibration of detectors can be performed with a single isotope, and without removing or adjusting a collimator attached to the detector.
