Patent number: 10176962Abstract: An X-ray emitter has an X-ray tube which contains a vacuum envelope in which an emitter and an anode are disposed. The emitter can be heated by an external flat emitter filament supply. Accordingly the emitter is configured as a filament emitter and an interface circuit is arranged between the filament emitter and the flat emitter filament supply. In this manner, a flat-emitter-based X-ray emitter can be replaced by a filament-emitter-based X-ray emitter in an X-ray emitter system without any configuration changes.Type: GrantFiled: August 18, 2016Date of Patent: January 8, 2019Assignee: Siemens Healthcare GmbHInventors: Stefan Setzer, Stephan Sons

Patent number: 8598814Abstract: A method for pulsed operation of a linear accelerator includes generating pulses of charged particles. The generating includes emitting particles by a particle source and accelerating the particles in an accelerator device that includes a plurality of linked cavity resonators. The accelerator device is supplied with energy by an energy supply unit. Particle energy is changed solely by varying a number of particles emitted by the particle source per pulse.Type: GrantFiled: May 3, 2012Date of Patent: December 3, 2013Assignee: Siemens AktiengesellschaftInventors: Marvin Möller, Sven Müller, Stefan Setzer

Publication number: 20130113503Abstract: The invention relates to a method and device for measuring the location of a particle beam (10) present in packets in a linear accelerator comprising a hollow chamber structure (4) in which an electromagnetic wave oscillating at a base frequency (f0) is generated in order to accelerate the particles, wherein an electrical measurement signal (M) generated by the particle beam (10) by means of electromagnetic interaction with the measurement recorder (16) is recorded by at least one measurement recorder (16) disposed in the hollow chamber structure (4), said signal being a function of the distance between the measurement recorder (16) and the particle beam (10). According to the invention, the measurement signal (M) is analyzed in a frequency range different from the base frequency (f0) and higher natural frequencies of the hollow chamber structure (4), comprising a whole multiple of the base frequency (f0).Type: ApplicationFiled: November 4, 2010Publication date: May 9, 2013Inventors: Marcel Ruf, Lorenz-Peter Schmidt, Stefan Setzer
