Abstract
An X-ray imaging system utilizing a pixelated X-ray source and a X-ray imaging detector operated synchronously. The imaging system may be used in industrial and medical applications. The X-ray source and X-ray detector are synchronized such that a corresponding area of the X-ray detector is activated when the corresponding area of the X-ray source is emitting X-rays. Synchronized and adaptive emission and detection of the X-rays results in scatter rejection, improved image quality, and optimum exposure and dose reduction.
Claims20
An X-ray system for examining an object comprising:
- a source of X-rays operated such that the X-rays are emitted from only a portion of the surface of the X-ray source;
- an X-ray detector having means such that only a portion of the X-ray detector is active at any one time;
- means for synchronizing the X-ray source and X-ray detector such that a corresponding area of the X-ray detector is activated when the corresponding area of the X-ray source is emitting X-rays;
- and
- feedback means for monitoring the X-ray flux received by each of the individual X-ray detecting portions of the X-ray detector;
- and controlling the amount of flux received by each of the active portions in response to the monitored X-ray flux.
An X-ray system for examining an object comprising:
- an X-ray source comprising individually addressable X-rays emitting portions;
- means for activating the individual X-rays emitting portions in a predetermined sequence an X-ray detector comprising individually addressable X-rays detecting portions;
- means for activating the individual X-rays detecting portions in a predetermined sequence,
- means for synchronizing the X-ray source activating means and X-ray detector activating means such that a corresponding portion of the X-ray detector is activated when the corresponding portion of the X-ray source is emitting X-rays;
- means for monitoring the X-ray flux received by each of the individual X-rays detecting portions of the X-ray detector;
- and
- means for controlling the amount of flux received by each of the individual X-rays detecting portions in response to the monitored X-ray flux.
An X-ray system for examining an object comprising:
- an X-ray source comprising individually electronically addressable X-ray emitting pixels;
- electronic means for addressing the individual X-rays emitting pixels in a predetermined sequence
- an X-ray detector comprising electronically individually addressable X-ray detecting pixels;
- means for addressing the individual X-rays detecting pixels in a predetermined sequence,
- electronic means for synchronizing the X-ray source addressing means and X-ray detector addressing means such that a corresponding portion of the X-ray detector is activated when the corresponding portion of the X-ray source is emitting X-rays, said electronic means including means for adjusting the exposure of the X-rays detecting pixels in accordance with the amount of X-rays impinging thereon.
