3D X-Ray Reconstruction

Invention Number: 
10_2539
A method for reconstructing 3D images from an almost standard 2D x-ray setup. The sensor developed by UNSW generates representation of the internal structure using x-ray radiation.

The Opportunity

UNSW has developed a sensor for generating a representation of the internal structure of an object using x-ray radiation.  The apparatus operates as a CT/PET/SPECT device without moving parts.  This reduces the size, weight and cost of the device, which enhances portability, accessibility and image acquisition time.

The Technology

This technology is a method for reconstructing 3D images from an almost standard 2D x-ray setup.
The technology involves the use of variably: pinholes, zone plates (x-ray focussing structures) and tomographic reconstruction techniques to generate 3D volumes and images at high resolution, and at high speed from a single x-ray exposure. The process is analogous to the lightfield imaging technique of plenoptic imaging, where the focus point and depth of field of an image may be altered after a single exposure has been taken.

Key Benefits
• 3D imaging information from a single exposure
• Significant cost savings on existing techniques by reducing the number of radiation sources  and sensors

Applications
• New designs and retrofitting of 2D x-ray installations to deliver 3D imaging information
• Streaming (high frame rate) 3D x-ray imaging
