Abstract
The present disclosure provides methods and systems for X-ray imaging. The methods may include obtaining pre-scan imaging data relating to a target section of a target subject. The methods may include determining, based on the pre-scan imaging data, a chord length of at least one chord of the target section. The methods may also include determining, based on the chord length of the at least one chord of the target section, exposure parameters to be used by the X-ray imaging device in a target scan of the target subject. The methods may further include reconstructing a target image of the target subject based on scan data collected by the X-ray imaging device in the target scan.
Claims20
A system, comprising:
- at least one storage device storing a set of instructions for X-ray imaging;
- and
- at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
- obtaining pre-scan imaging data relating to a target section of a target subject, the pre-scan imaging data being collected by a detector of an X-ray imaging device in a pre-scan, and the target section being irradiated by pre-scan radiation rays emitted by a radiation source located at a fixed location during the pre-scan;
- determining, based on the pre-scan imaging data, a chord length of at least one chord of the target section, an extension line of each of the at least one chord passing through a focal spot of the radiation source and a detector position of the detector;
- determining, based on the chord length of the at least one chord of the target section, exposure parameters to be used by the X-ray imaging device in a target scan of the target subject;
- and
- reconstructing a target image of the target subject based on scan data collected by the X-ray imaging device in the target scan, the target scan being performed according to the exposure parameters.
A method for X-ray imaging, implemented on a computing device having at least one processor and at least one storage device, the method comprising:
- obtaining pre-scan imaging data relating to a target section of a target subject, the pre-scan imaging data being collected by a detector of an X-ray imaging device in a pre-scan, and the target section being irradiated by pre-scan radiation rays emitted by a radiation source located at a fixed location during the pre-scan;
- determining, based on the pre-scan imaging data, a chord length of at least one chord of the target section, an extension line of each of the at least one chord passing through a focal spot of the radiation source and a detector position of the detector;
- determining, based on the chord length of the at least one chord of the target section, exposure parameters to be used by the X-ray imaging device in a target scan of the target subject;
- and
- reconstructing a target image of the target subject based on scan data collected by the X-ray imaging device in the target scan, the target scan being performed according to the exposure parameters.
A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:
- obtaining pre-scan imaging data relating to a target section of a target subject, the pre-scan imaging data being collected by a detector of an X-ray imaging device in a pre-scan, and the target section being irradiated by pre-scan radiation rays emitted by a radiation source located at a fixed location during the pre-scan;
- determining, based on the pre-scan imaging data, a chord length of at least one chord of the target section, an extension line of each of the at least one chord passing through a focal spot of the radiation source and a detector position of the detector;
- determining, based on the chord length of the at least one chord of the target section, exposure parameters to be used by the X-ray imaging device in a target scan of the target subject;
- and
- reconstructing a target image of the target subject based on scan data collected by the X-ray imaging device in the target scan, the target scan being performed according to the exposure parameters.
