Abstract
A method and system of aligning an x-ray detector and x-ray tube for data acquisition are presented. The x-ray detector and x-ray tube are equipped with transmitters and receivers designed to provide feedback relating to the orientation, spacing, and general position thereof. In this regard, a user can effectively and efficiently position the x-ray tube and x-ray detector relative to one another for data acquisition.
Claims21
An x-ray detector comprising:
- a scintillator designed to output light in response to reception of x-rays;
- a detector element array configured to detect light output from the scintillator and output electrical signals indicative of the x-rays received by the scintillator for image reconstruction;
- a plurality of electronic position sensors;
- and
- a controller configured to receive and process feedback from the plurality of electronic position sensors and to determine, from the feedback, perpendicularity of a plane of the scintillator relative to an x-ray source.

An x-ray imaging system comprising:
- an x-ray source configured to provide a beam of x-rays at a subject to be imaged;
- a positionable x-ray detector configured to detect x-rays attenuated by the subject;
- a plurality of sensors designed to receive feedback from at least one energy source;
- and
- a controller configured to process the feedback and to electronically determine, from the processed feedback, if a plane of the positionable x-ray detector is substantially perpendicular to the beam of x-rays during imaging of the subject.
2 more elements
An x-ray detector comprising:
- means for converting x-rays into electrical signals capable of being processed for reconstruction of an image;
- and
- means for electronically determining orientation of the converting means relative to an x-ray source such that a plane of the converting means is substantially perpendicular to an x-ray beam during data acquisition.
An x-ray detector comprising:
- a scintillator designed to output light in response to reception of x-rays;
- a detector element array configured to detect light output from the scintillator and output electrical signals indicative of the x-rays received by the scintillator for image reconstruction;
- a plurality of electronic position sensors;
- and
- a controller configured to receive output from the plurality of electronic position sensors and triangulate a position of the scintillator.
