Abstract: A curved compression element, such as a breast compression paddle, and imaging systems and methods for use with curved compression elements. A system may include a radiation source, a detector, and a curved compression element. Operations are performed that include receiving image data from the detector; accessing a correction map for the at least one compression paddle; correcting the image data based on the correction map to generate a corrected image data; and generating an image of the breast based on the corrected image data. The breast compression element generally has no sharp edges, but rather has smooth edges and transitions between surfaces. The breast compression paddle also includes a flexible material that spans a portion of a curved bottom surface of the breast compression paddle to define a gap. The flexible material may be a thin-film material such as a shrink wrap.

Abstract: A hybrid image based on different tissue specimen images is generated to compensate for blood and other fluids that interfere with imaging. Specimen is deposited into tray with fluid. X-ray and camera imaging devices acquire images of specimen and fluid. X-ray and optical images are processed for generation of hybrid image. Transparency modifications allow for multiple and different images to contribute to depiction of specimen edges or boundaries that would otherwise appear less clear in x-ray image due to interfering fluid. Transparency modifications in hybrid image also provide for sufficiently high transparency in certain optical image portions that would otherwise be opaque so that objects of interest depicted in x-ray image but not optical image are visible.

Abstract: A method of detecting and quantifying human objects in a given environment by passively observing wireless signals in an interesting environment. Information pertaining to observed wireless signals, such as wireless physical layer data and metadata, encrypted or unencrypted data and metadata in the wireless media-access control layer, and channel state information are extracted from the observed wireless signals and used to detect and quantify human objects in a location. The signals that are observed can originate from a wireless object used by a target of interest, such as cellular phone or workstations, or from infrastructure devices, such as wireless access points, IoT devices, or other transceivers. The signals can also originate from other recognizable signal sources, such as electromagnetic interference introduced by equipment such as elevator motors or microwave ovens.
