Abstract
A method includes identifying projection data generated during an x-ray tube arc event, determining x-ray tube voltages for data points of the identified projection data, correcting the identified data points based on the determined x-ray tube voltages for the data points, and reconstructing projection data that includes projection data generated during non x-ray tube arc events and the corrected projection data, and a system includes a projection data processor (116) that corrects projection data corresponding to data acquired during an x-ray tube arc event.
Claims20
A method, comprising:
- identifying projection data generated during an x-ray tube arc event;
- determining x-ray tube voltages for data points of the identified projection data;
- correcting the identified data points based on the determined x-ray tube voltages for the data points;
- and
- reconstructing projection data that includes projection data generated during non x-ray tube arc events and the corrected projection data.
A system, comprising:
- a projection data processor that corrects projection data corresponding to data acquired during an x-ray tube are event.
A method of correcting data collected during an x-ray tube arc, comprising:
- identifying the tube arc;
- establishing a relationship between x-ray attenuation values and x-ray tube voltage;
- determining one or more x-ray tube voltages at different time periods during the tube arc;
- and
- using the relationship to determine a correction values for x-ray attenuation values during the x-ray tube arc.
