Systems and methods for determining a mass of a crop by using at least one X-ray scanner is provided. The method includes obtaining at least two scan images of the crop, where a first of the at least two images is obtained along a first plane relative to the crop and a second of the at least two images is obtained along a second plane relative to the crop, and where the first plane is angularly displaced relative to the second plane, registering the first image and the second image, correcting the registered first and second images, and determining the mass of the crop from the corrected first and second images.

Systems and methods for using backscatter imaging in precision agriculture

The present specification describes a system for synchronizing a transmission detector and a backscatter detector integrated with a portable X-ray scanner. The system includes a transmitter connected with the transmission detector for transmitting the analog detector signal and a receiver connected with the scanner for receiving the transmitted analog detected signal where the transmitter and the receiver operate in the ultra-high frequency range.

Methods and systems for synchronizing backscatter signals and wireless transmission signals in x-ray scanning

The present specification provides a detector for an X-ray imaging system. The detector includes at least one high resolution layer having high resolution wavelength-shifting optical fibers, each fiber occupying a distinct region of the detector, at least one low resolution layer with low resolution regions, and a single segmented multi-channel photo-multiplier tube for coupling signals obtained from the high resolution fibers and the low resolution regions.

Handheld backscatter imaging systems with primary and secondary detector arrays

The present specification describes an X-ray detector that includes at least one scintillator screen for absorbing incident X rays and emitting corresponding light rays, a wavelength shifting sheet (WSS) coupled with the at least one scintillator screen for shifting the emitted light rays, at least one wavelength shifting fiber (WSF) coupled with at least one edge of the WSS for collecting the shifted light rays, and a photodetector for detecting the collected light rays.

Wireless transmission detector panel for an X-ray scanner

Methods for characterizing living plants, wherein one or more beams of penetrating radiation such as x-rays are scanned across the plant under field conditions. Compton scatter is detected from the living plant and processed to derive characteristics of the living plant such as water content, root structure, branch structure, xylem size, fruit size, fruit shape, fruit aggregate volume, cluster size and shape, fruit maturity and an image of a part of the plant. Ground water content is measured using the same technique. Compton backscatter is used to guide a robotic gripper to grasp a portion of the plant such as for harvesting a fruit.

Spectral discrimination using wavelength-shifting fiber-coupled scintillation detectors

Methods for discriminating among x-ray beams of distinct energy content. A first volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides that convert the scintillation light to light of a longer wavelength. An x-ray beam initially incident upon the first volume of scintillation medium and traversing the first volume is then incident on a second volume of scintillation medium. The first and second scintillation media may be separated by an absorber or one or more further volumes of scintillation medium, and may also have differential spectral sensitivities. Scintillation light from the first and second scintillation volumes is detected in respective detectors and processed to yield a measure of respective low energy and high-energy components of the incident x-ray beam.
