Abstract
An imaging array has imaging pixels, non-uniform septa, an axial center and a radial perimeter. The septa are positioned in the array such that there is a septum between adjacent ones of the imaging pixels. At least one parameter of the septa varies at least once from the center to the perimeter of the array. The parameter may increase from the center to the perimeter. The parameter may comprise density or atomic number of the septa. Alternatively, the parameter of the septa may be their radial thicknesses which vary relative to the center.
Claims50
An imaging array, comprising:
- a plurality of imaging pixels that form an array, the array having a high energy end, a light exit end, an axial center and a radial perimeter;
- septa positioned in the array such that there is a septum between adjacent ones of the imaging pixels;
- and
- at least one parameter of the septa is varied at least once from the septa adjacent the axial center of the array to the septa adjacent the radial perimeter of the array.
A scintillator pixel array, comprising:
- a plurality of scintillation pixels that form an array, the array having a high energy end, a light exit end, an axial center and a radial perimeter;
- septa positioned in the array in strata, such that there is a septum between adjacent ones of the scintillation pixels;
- and
- at least one physical parameter of the septa varies with each strata of septa from the strata of septa adjacent the axial center of the array to the strata of septa adjacent the radial perimeter of the array.
A machine, comprising:
- a source of radiant energy for emitting energy;
- an imaging array, comprising:
- a plurality of imaging pixels that form an array, the array having a high energy end for receiving the emitted energy, a light exit end, an axial center and a radial perimeter;
- septa positioned in the array such that there is a septum between adjacent ones of the imaging pixels;
- and
- at least one parameter of the septa is varied at least once from the septa adjacent the axial center of the array to the septa adjacent the radial perimeter of the array;
- an output device for displaying an image from the light exit end;
- and
- a user interface coupled to the source of radiant energy and output device.
