Abstract
A system for scanning an x-ray target in an x-ray imaging system with a charged particle beam. The system for scanning comprises deflecting the charged particle beam to re-illuminate the portion of the object to be imaged in a time period that is sufficiently small to prevent image blurring during image reconstruction. The system for scanning further comprises a scan processing system for processing x-ray transmissiveness information received as a result of a scanning pattern that re-illuminates an object.
Claims17
A scan processing system for processing x-ray transmissiveness information comprising:
- a scan processing module at which related x-ray transmissiveness information from multiple x-ray illuminations of an object to be imaged by an x-ray source received by a detector comprising a plurality of detector elements, are dynamically summed;
- a random access memory at which intermediate results from said scan processing module are temporarily stored and communicated back to said scan processing module;
- and
- a data transmitter, said data transmitter coupled to said scan processing module for reception of image information from said scan processing module, and said data transmitter having a transmitter output communicatively coupled to an image reconstruction system.
1 more element
An imaging system comprising:
- an x-ray source comprising a charged particle beam source and an x-ray target assembly, said charged particle beam source generating a particle beam that scans across said x-ray target assembly in a scanning pattern said scanning pattern rescans a portion of said x-ray target assembly a plurality of times during a frame;
- a plurality of detection elements configured to detect x-rays generated by said x-ray target assembly;
- each of said plurality of detection elements having a detection output comprising x-ray transmissiveness information;
- and
- a scan processing system comprising
- a scan processing module, said scan processing module configured to dynamically combine related x-ray transmissiveness information received at said plurality of detection elements;
- and
- a cache memory, said cache memory configured to store intermediate results from said scan processing system.
