Abstract
Among other things, one or more techniques and/or systems are described for reducing a voltage ripple in an electric signal. In this way, in radiographic imaging modalities, for example, undesired fluctuations in an output of a radiation source (e.g., undesirable fluctuations in an energy level of emitted photons) may be reduced. To reduce the voltage ripple, a (ripple reducing) electric signal is generated that comprises properties substantially similar to the voltage ripple, but opposite in phase. The (ripple reducing) electric signal is then combined with the original electric signal to generate a combined electric signal with a voltage ripple that is reduced relative to the voltage ripple of the electric signal as initially generated.
Claims20
A system for reducing fluctuation in an output of a radiation source of an imaging modality, comprising:
- a waveform generator component configured to generate a second electric signal, the second electric signal configured to be combined with a first electric signal generated by a power supply component to reduce a voltage ripple of the first electric signal and to yield a combined electric signal that when input into the radiation source of the imaging modality causes fluctuation in the output of the radiation source to be reduced relative to fluctuation in the output of the radiation source if the first electric signal were input into the radiation source.
A method for reducing voltage ripple, comprising:
- generating a second electric signal via a waveform generator component that is configured to be combined with a first electric signal to generate a combined electric signal comprising a voltage ripple that is reduced relative to a voltage ripple of the first electric signal.
A computer readable medium comprising computer executable instructions that when executed via a processing unit perform a method for reducing voltage ripple, the method comprising:
- generating a second electric signal via a waveform generator component that is configured to be combined with a first electric signal to generate a combined electric signal comprising a voltage ripple that is reduced relative to a voltage ripple of the first electric signal.
