A portable detector for use with an imaging system is disclosed. The portable detector automatically sets one or more operational states based on at least a determination as to whether the portable detector is connected to external power. An imaging system is also disclosed that ascertains whether the portable detector is connected via a tether. The imaging system may perform a compatibility check when connected to the portable detector to assess compatibility between the imaging system and the portable detector.

Portable radiation detector and system

A system and method for an improved digital X-ray radiographic tomosynthesis user interface and workflow. The system comprising a user interface providing a tomosynthesis reconstruction preference edit tool; a dose preference edit tool; a scout acquisition edit tool; a tomosynthesis acquisition edit tool; a retrospective reconstruction image processing edit tool; a slice image change auto forward edit tool; and an image annotation propogation edit tool.

System and method for a digital X-ray radiographic tomosynthesis user interface

A method for creating a variable slice thickness for displaying an imaged object is disclosed. The method includes acquiring a plurality of projection images from a plurality of different projection angles within a defined sweep angle, reconstructing a plurality of object images from the plurality of projection images, each object image having a first slice thickness, and applying a function rule to combine images, whole images or portions thereof or attributes thereof, of the plurality of projection images, of the plurality of object images, or of both, thereby providing for the display of the object utilizing a second slice thickness that varies from the first slice thickness.

Method and system to generate object image slices

A method and apparatus for tomosynthesis image quality control for a tomosynthesis imaging system. The method and apparatus including: positioning a phantom having an edge of predetermined sharpness at a predetermined angle relative to an imaging plane of an x-ray detector; performing tomosynthesis acquisition and generating one or more slice images using one or more three-dimensional reconstruction algorithms; selecting a slice image to be measured from the one or more slice images; identifying a sharpest edge in the slice image to be measured, wherein the sharpest edge in the slice image to be measured includes the in-focus portion of the phantom; inputting the slice image to be measured and coordinates of the sharpest edge in the slice image to be measured into a modulation transfer function (MTF) algorithm; and, using the MTF algorithm, calculating the in-plane resolution and slice thickness of the slice image to be measured.

Method and apparatus for tomosynthesis image quality control

A digital radiographic imaging system includes an offset table for determining mechanical and structural offsets which would, if not corrected, misalign the source and detector during use. The method can correct for inaccuracies in mechanical linkages, examination rooms and other mounting structures, and 'drift' induced during use of the system.

Method and apparatus for aligning an X-ray source and detector at various source to image distances

A system and method for automatically positioning an image receptor based on the position of a manually positioned diagnostic source assembly in an X-ray imaging device is provided. In a preferred embodiment of the automated tracking system, an operator manually positions a diagnostic source assembly (DSA) over the area of a patient to be imaged. Sensors in the diagnostic source assembly transmit the position of the DSA to a system controller. The system controller then calculates an optimal position of an image receptor based on the position of the DSA. Once the optimal position is calculated, the system controller sends the optimal position to a motor drive, which positions the image receptor in the calculated optimal position. Position sensors in the image receptor then send positional data of the image receptor to the system controller, which verifies that the image receptor is in the calculated optimal position. If the operator wishes to manually adjust the image receptor, they may override the motor drive and do so. The automated tracking system provides for reduced total imaging time and increased cost effectiveness over prior X-ray imaging systems by reducing the number of retakes required to obtain a satisfactory X-ray image. Reducing retakes also results in decreased exposure to radiation by the patient being imaged which is healthier to the patient.
