Method and apparatus for improved sampling resolution in x-ray imaging systems

A method for image reconstruction comprising:

• positioning an object for imaging between a radiation source having rows and columns of discrete emissive locations and a radiation sensor having rows and columns of sensing elements, wherein an angular offset exists between said rows and columns of sensing elements and said rows and columns of said discrete emissive locations, respectively;
• illuminating a portion of said object with radiation from one of said discrete emissive locations;
• detecting responses of said sensing elements to said radiation;
• allocating said responses into a data set wherein data rows correspond to unique positions along a direction of columns of said discrete emissive locations;
• and
• determining mapping coefficients relating said data set to an image plane.

A method for optimizing sampling resolution of an imaging system comprising:

• positioning a radiation source that has columns of discrete emissive locations on a first side of an imaging volume;
• positioning a radiation sensor that has columns of sensing elements on a second side of said imaging volume such that an angular offset less than 90 degrees exists between said columns of said discrete emissive locations and said columns of sensing elements;
• illuminating a portion of said imaging volume with radiation from one of said discrete emissive locations;
• and
• recording responses of each of said sensing elements.
