Abstract
A method includes receiving cine scan data, receiving a plurality of target phases of a periodic waveform, and generating a plurality of images, each image centered at one of the received target phases. A phase shall represent a percentage of a period of a repeating cycle.
Claims18
A method comprising:
- receiving cine scan data;
- receiving a plurality of target phases of a periodic waveform;
- generating a plurality of images, each image centered at one of the received target phases;
- performing a waveform analysis on the periodic waveform to detect an aberration;
- and
- shifting the center of at least one image to correct for the detected aberration.
3 more elements
A method comprising:
- performing a waveform analysis to detect an aberration;
- prompting a user when an aberration is detected;
- and
- shifting the center of at least one image to correct for the detected aberration.
1 more element
A system for reconstructing images, said system comprising:
- a radiation source;
- a radiation detector positioned to receive radiation emitted from said source;
- and
- a computer coupled to said source and said detector, said computer configured to:
- receive scan data from said detector;
- perform a temporal synchronization of the scan data using a waveform received from an external device or other means of quantifying periodic motion;
- perform a waveform analysis to detect an aberration;
- and
- shift the center of at least one image to correct for the detected aberration.
6 more elements
A method comprising:
- receiving at least one target phase;
- scanning a periodic moving object to obtain at least one complete waveform of the periodic motion;
- using the waveform to prospectively gate acquisitions around the target phase;
- performing a waveform analysis to detect an aberration;
- and
- shifting the center of at least one image to correct for the detected aberration.
