Abstract
An apparatus for energizing a large scale medical imaging system, preferably in the form of a CT scanner so that the scanner operates off an uninterruptable power supply in the event that the external power falls below sufficient power to operate the system so that system operation remains uninterruptable. The system is designed to operate off a broad range and types of external power supplies including those providing DC, single or three phase AC power. The system therefore can operate from a common single phase AC outlet. In addition, power factor correction is provided so that the system can correct for phase differences between the voltage and current at the input line created by the input impedance of the system.
Claims29
A computed tomography imaging apparatus comprising a disk for rotatably supporting an x-ray source and x-ray detection means for use in generating a scanned image during a scanning operation, the apparatus further comprising:
- uninterruptible power supply means for storing at least sufficient energy for operating said apparatus through an entire scanning operation;
- power supply assembly means for providing power to the apparatus;
- means for receiving electrical power from an external power source so as to simultaneously apply electrical power to said apparatus during a scanning operation and to said uninterruptible power supply means;
- and
- means for applying power stored in said uninterruptible power supply means to said means for receiving said electrical power from an external power source so that said apparatus utilizes external power from said external power source when said external power is sufficient to operate said apparatus during a scanning operation, and immediately utilizes power from said uninterruptible power supply means when said external power is insufficient to operate said apparatus so as to provide uninterrupted operation of said apparatus through the entire imaging operation.
A computed tomography scanning apparatus including a rotatable disk for rotatable supporting a x-ray source and x-ray detection system for use in generating a scanned image during a scanning operation, the apparatus comprising:
- means for receiving electrical power from an external power source, and for providing at least one regulated DC power signal;
- means for receiving and storing energy from said regulated DC power signal until at least an amount of energy that is sufficient to complete a scanning operation;
- and
- means for applying said energy from said means for receiving and storing energy to said means for receiving electrical power so as to provide an uninterruptible supply of energy for completing a scanning operation without interruption.
