    摘要： An x-ray system (10) include a digital detector (400) that defines two regions: a first region (404) suitable for generating data useful for creating a patient x-ray image and a second region (406) less suitable for generating such data than the first region. A source (20) transmits x-rays through a phantom (420) located between the source and the second region (406) so that the detector (400) generates test data in the second region. A processor (302) measures at least one parameter in response to the test data and stores a value of the parameter at one point of time. The processor compares the first value with a second value of the one parameter generated at a later second point in time. The processor also generates a result signal representing the results of the comparison.

    摘要： A method is provided for maximizing substrate usage in the fabrication of flat panel displays or detectors, while also maximizing electrostatic protection for the displays or detectors. Initially, at least two detectors are positioned on the substrate, with each of the detectors having a guard ring of a certain width. At least a section of the guard ring width of one detector is approximately adjacent to a section of the guard ring width of another detector. The approximately adjacent guard ring width sections are then positioned such that a maximum overlap of the adjacent guard ring width sections is achieved, while still providing each display or detector with electrostatic discharge protection. Each of the detectors is separated from the other detectors and the remainder of the substrate by the process of scribing partially through the substrate and breaking at the scribe mark or by sawing.

    摘要： A portable x-ray detector is disclosed that includes an x-ray detecting member and a user removable electromagnetic interference (EMI) shielding member. The user removable EMI shielding member is positioned to at least partially magnetically shield the x-ray detecting member of the portable x-ray detector by redirecting an impinging magnetic field around the x-ray detecting member. The user removable EMI shielding member includes a first magnetic shielding layer, a second magnetic shielding layer, and an intervening material, other than the x-ray detecting member, between the first magnetic shielding layer and the second magnetic shielding layer.

    摘要： Systems and methods are provided by which a mammography imaging system offers X-ray and ultrasound imaging that allows sharing of common hardware such as the computer and display. Small regions of interest are imaged with X-ray at higher image quality by using a second sensor with higher DQE than the full-field sensor can obtain. In some embodiments a specialized chamber is provided for securing the anatomy to a fixed location, ultrasound image data is collected along with ultrasound probe location and orientation data from sensors on a handheld probe from which data images can be viewed directly, or used to reconstruct tomographic images of any desired cross-section, or used for various “3-D” image visualization methods. An imaging schedule defined by location and orientation of an ultrasound probe is used to generate a three-dimensional ultrasound image.
