Method and system for dual or multiple energy imaging

A system for dual or multiple energy imaging, the system comprising:

• an energy source configured to emit energy at a first exposure interval and at a second exposure interval after said first exposure interval;
• a detector comprising a plurality of cells, said detector being configured to:
• receive said energy emitted at said first exposure interval and provide a first image data set indicative of said energy emitted at said first exposure interval,
• receive said energy emitted at said second exposure interval and provide a second image data set indicative of said energy emitted at said second exposure interval,
• provide a first offset image data set, said first offset image data set indicating a retained charge in said plurality of cells at a predetermined amount of time after said second exposure interval, and
• provide a second offset image data set, said second offset image data set indicating a retained charge in said plurality of cells at a predetermined amount of time after said first offset image data set is provided;
• and
• an image acquisition module configured to apply said first offset image to compensate for said retained charge in said plurality of cells at said predetermined amount of time after said second exposure interval, and apply said second offset image to compensate for said retained charge in said plurality of cells at said predetermined amount of time after said first offset image data set is provided.

A method for a minimizing artifacts in dual or multiple energy imaging, the method comprising:

• exposing a detector to a first exposure from an energy source during a first exposure interval;
• after said first exposure interval, obtaining a first image data set during a first read time;
• after said first read time, exposing said detector to a second exposure from energy source during a second exposure interval;
• after said second exposure interval, obtaining a second image data set during a second read time;
• and
• a step for reducing the time between said exposing said detector to said first exposure and said obtaining said second image data set.

A method for a minimizing artifacts and total exam time between acquisitions in dual or multiple energy imaging, the method comprising:

• (a) exposing a detector to a first exposure from an energy source during a first exposure interval;
• (b) after said first exposure interval, obtaining a first image data set during a first read time;
• (c) after said first read time, exposing said detector to a second exposure from said energy source during a second exposure interval;
• (d) after said second exposure interval, obtaining a second image data set during a second read time;
• and
• (e) after said first read time and before said second exposure interval, changing a pixel acquisition resolution of said detector.
