An imaging apparatus 10 for generating an image of a subject including a scanning arrangement which includes an energy emitting source 20 and a detector 22 housed within a housing 12. The housing defines a scanning zone 24 in which the subject is operatively positioned for scanning A displacing arrangement 36 which includes a U-shaped belt-and-pulley drive arrangement is configured to displace the scanning arrangement relative to the housing 12 in a scanning direction. The housing 12 has a first door and second door defining a substantially linear pathway through the scanning zone. A motor 38 and horizontal drive belts 40 are disposed below the scanning zone and are not displaced relative to the housing in the scanning direction in which the energy emitting source and detector are displaced during scanning such that the displacing arrangement does not restrict or impede movement of the subject through the scanning zone.

A drive-through scanning system comprises a radiation generating means arranged to generate radiation at two different energy levels and direct it towards a scanning volume, detection means arranged to detect the radiation after it has passed through the scanning volume, and control means arranged to identify a part of a vehicle within the scanning volume, to allocate the part of the vehicle to one of a plurality of categories, and to control the radiation generating means and to select one or more of the energy levels depending on the category to which the part of the vehicle is allocated.

A mobile detection device and a detection method are provided. The mobile detection device includes: a bearing platform, being arranged fixedly, and including a bearing surface bearing an object to be detected; a movable gantry, located on a side of the bearing surface bearing the object to be detected and configured to be movable relative to the bearing platform; a movable bearing device, located on a side of the bearing surface away from the movable gantry and configured to be movable relative to the bearing platform; a first radiation source, arranged on one of the movable gantry and the movable bearing device, and a first detector array, arranged opposite to the radiation source and arranged on the other of the movable gantry and the movable bearing device, wherein the movable gantry and the movable bearing device are configured to be moved synchronously relative to the bearing platform.

The present application is directed toward cargo scanning systems having scanners, each arranged to scan a respective object and generate a set of scan data, processors arranged to process each set of scan data to determine whether it meets a predetermined threat condition, workstations, and data management system arranged to direct data that meets the threat condition to one of the workstations for analysis.

Imaging systems and methods are provided for detecting object that may be hidden under clothing, ingested, inserted, or otherwise concealed on or in a person's body. An imaging assembly and mechanisms for vertically moving the imaging assembly may be configured to reduce the overall form factor of such imaging systems, while still retaining an ability to perform full/complete imaging of a subject. A calibration system assembly can be included, comprising a first calibration assembly and second calibration assembly to perform fine-grained adjustments to the positioning of the X-ray detector.

The present invention provides a four-sided scanning system for vehicles that uses a combination of backscatter and transmission based X-ray imaging to achieve material discrimination. In one embodiment, the system is designed as a mobile, drive-through system, which can be folded and stowed in a truck and can be conveniently deployed at any place when required.

The present specification describes a compact, hand-held probe or device that uses the principle of X-ray backscatter to provide immediate feedback to an operator about the presence of scattering and absorbing materials, items or objects behind concealing barriers irradiated by ionizing radiation, such as X-rays. Feedback is provided in the form of a changing audible tone whereby the pitch or frequency of the tone varies depending on the type of scattering material, item or object. Additionally or alternatively, the operator obtains a visual scan image on a screen by scanning the beam around a suspect area or anomaly.

An X-ray scanner includes a frame; an X-ray generator mounted within the frame, and outputting a vertical fan-shaped beam toward an object; the X-ray generator configured to rotate in a left-right direction; a linear vertical X-ray detector mounted in the frame beyond the object, the linear vertical X-ray detector configured to slide in sync with a rotation of the X-ray generator; a first flat panel X-ray detector below the object, the first flat panel X-ray detector being stationary; a second flat panel X-ray detector above the object, the second flat panel X-ray detector being stationary; a workstation that integrates scans from the first flat panel X-ray detector, the second flat panel X-ray detector and the linear vertical X-ray detector to generate a full-body scan of the object.

A method of creating a well image log of a cased well is provided. A passive cased well image logging tool assembly including a logging tool body, a plurality of gamma ray radiation sensors and a spatial positioning device is moved through at least a portion of the wellbore at a logging speed of no greater than 750 feet per hour. Corrected gamma ray radiation data is vertically sampled at a vertical distance sampling rate of once every vertical distance sampling interval, wherein the vertical distance sampling interval is no greater than 1.75 inches. Based on the sampled data, a well image log is prepared. A passive cased well image logging tool assembly for use in a cased well is also provided.

An X-ray scanner includes a frame; an X-ray generator mounted within the frame, and outputting a vertical fan-shaped beam toward an object; the X-ray generator configured to rotate in a left-right direction; a linear vertical X-ray detector mounted in the frame beyond the object, the linear vertical X-ray detector configured to slide in sync with a rotation of the X-ray generator; a first flat panel X-ray detector below the object, the first flat panel X-ray detector being stationary; a second flat panel X-ray detector above the object, the second flat panel X-ray detector being stationary; a workstation that integrates scans from the first flat panel X-ray detector, the second flat panel X-ray detector and the linear vertical X-ray detector to generate a full-body scan of the object.
