Abstract
A digital dental x-ray sensor and methods to align the digital dental x-ray sensor are disclosed herein. The digital dental x-ray sensor includes an autoclavable portion which includes an appendage and an x-ray sensor head including an x-ray capturing element, a camera, and an inertial measurement unit. Additionally, the digital dental x-ray sensor includes a non-autoclavable portion which includes a connector, a processor, and a power supply.
Claims20
A method for aligning a dental instrument comprising:
- capturing a first image from a first image sensor affixed to an x-ray sensor head, the first image captured at an origin position;
- determining a pending position of the x-ray sensor head with reference to the origin position;
- determining whether the first image shares a common axis of reference with an x-ray tube based on a correlation between the first image and a second image captured by a second image sensor affixed to the x-ray tube;
- calculating a position of the x-ray tube with reference to the pending position of the x-ray sensor head and the common axis of reference;
- and
- based on the position of the x-ray tube, determining whether the x-ray tube is perpendicularly aligned towards the x-ray sensor head when at the pending position.
A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
- capturing a first image from a first image sensor affixed to an x-ray sensor head, the first image captured at an origin position;
- determining a pending position of the x-ray sensor head with reference to the origin position;
- determining whether the first image shares a common axis of reference with an x-ray tube based on a correlation between the first image and a second image captured by a second image sensor affixed to the x-ray tube;
- calculating a position of the x-ray tube with reference to the pending position of the x-ray sensor head and the common axis of reference;
- and
- based on the position of the x-ray tube, determining whether the x-ray tube is perpendicularly aligned towards the x-ray sensor head when at the pending position.
A dental system, comprising:
- an x-ray sensor head, comprising:
- a first image sensor configured to capture a first image, the first image captured at an origin position;
- a memory, and
- one or more processors coupled to the memory, wherein the one or more processors are configured to:
- determine a pending position of the x-ray sensor head with reference to the origin position;
- determine whether the first image shares a common axis of reference with an x-ray tube based on a correlation between the first image and a second image captured by a second image sensor affixed to the x-ray tube;
- calculate a position of the x-ray tube with reference to the pending position of the x-ray sensor head and the common axis of reference;
- and
- based on the position of the x-ray tube, determine whether the x-ray tube is perpendicularly aligned towards the x-ray sensor head when at the pending position.
