Abstract
Provided herein are x-ray imaging systems, methods of x-radiography, and methods of manufacture of collimators suitable for use in x-ray imaging systems and methods of x-radiography. The systems, methods and devices proposed here may assist in providing for improved magnification of x-rays in an x-ray imaging system with improved image quality compared to known systems. It may find applications in a variety of x-ray applications, for example x-ray CT (Computed Tomography) and 2D projectional radiography for e.g. non-destructing testing purposes.
Claims21
X-ray imaging system comprising:
- an x-ray source;
- a collimator having a body comprising an array of channels;
- and
- a detector comprising an array of sensors, each sensor in the array being arranged to receive x-rays passing through a predetermined one of the channels in the array of channels;
- wherein the collimator is disposed proximal to the x-ray source and distal from the detector, such that an object imaging space is defined between the collimator and the detector.
A method of manufacture of a collimator comprising the steps of:
- providing a plurality of space-holding members;
- and
- forming a collimator body around the space-holding members such that the space-holding members define an array of channels through the collimator body.
A method of manufacture of a collimator, comprising the steps of:
- providing a plurality of foil layers, each having an array of holes;
- and
- stacking and bonding the foil layers to form a laminated collimator body comprising an array of channels defined by aligned holes of each foil layer.
