Abstract: A mechanism for rapidly detecting and localizing external markers placed on a patient in projection images. Markers can be detected even in the presence of dense surrounding anatomy and extensive patient motion. Once the positions of the marker points on the projection images are extracted, the marker points can be used to perform marker-based patient motion detection. In addition to motion correction, the rapid detection and localization may also be used for scanner calibration, automatic cephalometric measurements, and quality control assessment.

Abstract: A system and method for automatic detection of x-rays at an x-ray sensor. A source emits x-ray radiation towards an x-ray sensor, and the x-ray sensor automatically detects the x-ray radiation. The x-ray sensor automatically detects x-ray radiation by evaluating a time series and determining that a voltage threshold is crossed a certain amount of time earlier than the average time it takes the voltage threshold to be crossed from dark current and other noise.

Abstract: A method and a system for generating an image by obtaining x-ray image data, segmenting the x-ray image data into a first portion above a vertical threshold and a second portion below the vertical threshold. Further, the method and the system include generating an arch for the second plurality of slices, and generating an image based on the arch.

Abstract: An intraoral x-ray sensor with embedded standard computer interface. The sensor includes a data transfer cable with improved mechanical strength and heat transferring properties. The cable is quad-twisted USB cable and includes two data lines, a ground line, and fillers twisted within a metallic sheath, e.g., a metal braided shield. The cable is symmetrically organized about a centerline. The symmetric cable has an improved life due to the ability to withstand mechanical stress (e.g., rotational stress). The sensor includes a processor and a housing with an inner metallization layer. The sheath is coupled to the inner metallization layer to transfer heat generated by the processor from the inner metallization layer to the sheath.
