Patent number: 10819624Abstract: A method for communication between at least two computing facilities of a medical imaging facility via a single communication line is disclosed. In the method, communication information assigned to different communication types received in each case via a dedicated data input is merged to form data structures of a defined size to be transmitted via the communication line. The data structures are transmitted cyclically via the communication line with an interval of one cycle time and communication information of the different communication types is extracted from data structures received via the communication line and output at data outputs assigned to the respective communication types. The communication types include a first packet-oriented communication type and a second isochronous communication type corresponding to isochronous direct channel communication.Type: GrantFiled: October 23, 2018Date of Patent: October 27, 2020Assignee: SIEMENS HEALTHCARE GMBHInventors: Rudi Baumgartl, Nikolaus Demharter

Patent number: 10386431Abstract: A magnetic resonance tomography system has a frequency control device for temperature compensation, a temperature sensor, and a high frequency generator. An output frequency of an output signal from the high frequency generator is dependent on a value of a digital frequency variable, and a synthesis signal with the system frequency is generated dependent on the output signal. A temperature change is detected using the temperature sensor, a temperature-time function of the temperature is determined using the temperature change that has been detected, a time is determined at which a change in the digital frequency variables in the least significant bit brings about a change in the frequency of the synthesis signal that corresponds with a change in the system frequency due to a temperature, according to the interpolated temperature-time function, and the digital frequency variable in the least significant bit is changed at the specified time.Type: GrantFiled: September 7, 2017Date of Patent: August 20, 2019Assignee: Siemens Healthcare GmbHInventors: Rudi Baumgartl, Andrew Dewdney

Patent number: 9417303Abstract: A method for digital amplitude control and digital phase control of a high-frequency signal is provided. A digital command signal specifies in complex form, including a real subcomponent and an imaginary subcomponent, an amplitude and a phase of the high-frequency signal that is to be controlled. A digital activation signal is output to a high-frequency unit for the purpose of generating the high-frequency signal. A digital signal deviation value is received in complex form including a real subcomponent and an imaginary subcomponent. The signal deviation value expresses a deviation of the high-frequency signal from the command signal with respect to the amplitude and the phase. The digital activation signal is determined from the command signal while taking into consideration the signal deviation value. The determination of the real subcomponent and the imaginary subcomponent takes place separately in each case.Type: GrantFiled: February 6, 2013Date of Patent: August 16, 2016Assignee: Siemens AktiengesellschaftInventors: Rudi Baumgartl, Nikolaus Demharter
