Abstract: Effective atomic numbers associated with pixels in a region are received. An effective atomic number is associated with each pixel in the region. X-ray data for the region is received, and an item within the region is identified from the x-ray data. Some of the pixels in the region are correlated with the item such that the item is associated with an effective atomic number. An image of the region is rendered. The pixels of the item have a display style based on the effective atomic number of the item.

Abstract: Methods and apparatus for integrating a table with at least one X-ray source for medical imaging of patients. The apparatus comprises a table on which a patient may be placed, at least one X-ray source configured to generate X-rays at a plurality of X-ray source locations along a linear direction, wherein the at least one X-ray source is arranged to generate the X-rays such that at least some of the X-rays pass through a portion of the table in addition to passing through a portion of a patient placed on the table, and at least one detector array comprising a plurality of detector elements and arranged to detect the at least some of the X-rays passed through the portion of the patient placed on the table, wherein the at least one detector array comprises detector elements arranged in a two-dimensional configuration. Iterative reconstruction techniques may be used to reconstruct an image from X-ray data detected using the at least one detector.

Abstract: A volumetric image of a space is acquired from an imaging system. The space includes an object of interest and another object, and the volumetric image includes data representing the object of interest and the other object. A two-dimensional radiograph of the space is acquired from the imaging system. The two-dimensional radiograph of the space includes data representing the object of interest and the other object. The two-dimensional radiograph and the volumetric image are compared at the imaging system. A two-dimensional image is generated based on the comparison. The generated two-dimensional image includes the object of interest and excludes the other object.

Abstract: Methods, systems, and apparatus for transmitting a first set of continuous wave (CW) signals, where each CW signal of the first set of CW signals has a first signal frequency and the transmitter is turned off between transmission of each CW signal of the first set of CW signals. For each CW signal of the first set of CW signals, receiving a reflection of the CW signal, and selecting an analog to digital (A/D) sample of the reflection of the CW signal that does not contain ground reflections by selecting the A/D sample based on timing from the transmitter being turned off after transmission of the CW signal. Integrating the selected A/D samples from each of the CW signals of the first set of CW signals to obtain a single A/D sample for the first set of CW signals.

Abstract: Systems and methods for sensing targets on an opposite side of a wall are disclosed. In some aspects, the techniques include providing an indication to a user that portions of reflected radar signals were blocked by radiofrequency-blocking material at the wall. In some aspects, the techniques include identifying candidate targets as multipath echoes or motion-induced errors based on a correlation map.

Abstract: An imaging system exposes an object within a region to a beam of penetrating radiation. The beam of penetrating radiation is sensed on a side opposite the region from a source of the beam. An attenuation of the beam caused by passing the beam through the object is determined, the attenuation is compared to a threshold attenuation. If the attenuation exceeds the threshold attenuation, a parameter of the imaging system is adjusted based on the determined attenuation.

Abstract: Radiation is directed at an object, and radiation scattered by the object is sensed. An angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object is determined, and the angular distribution is evaluated. One or more atomic numbers, or effective atomic numbers, of materials composing the object is determined based on evaluating the angular distribution.
