Embodiments include a method, comprising: receiving from a first device at a second device, a request for a system identifier (ID) stored on the second device; and determining, by the second device, if the system ID stored on the second device has an empty value; when the system ID stored on the second device does not have the empty value, transmitting, by the second device to the first device, a response based on the system ID stored on the second device.

Detection of unauthorized components

A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.

An example imaging device for generating an image is disclosed. The device may include an imaging detector array configured to collect charges during a radiation exposure at the imaging detector array. The device may include a signal generator coupled with the imaging detector array. The signal generator may be configured to generate a detection signal based on the charges collected by the imaging detector array. The device may include an accelerometer configured to generate an acceleration signal indicative of external forces applied to the imaging device. The device may further include a signal processor coupled with the signal generator and the accelerometer. In response to a determination that the acceleration signal is below a predetermined disturbance threshold and the detection signal exceeds a predetermined threshold, the signal processor may be configured to generate the image based on the detection signal.

Imager with bump detection

A method of communicating between imaging components of an X-ray imaging system may include determining, by an initiator imaging component, whether a target imaging component is a primary manufacturer imaging component (PMIC). Responsive to the target imaging component not being the PMIC, the method may include generating a communication message including a communication packet according to a packet protocol. Responsive to the target imaging component not being the PMIC, the method may also include sending the communication message to the target imaging component as a secondary manufacturer imaging component. Responsive to the target imaging component being the PMIC, the method may include generating a message including a header packet and one or more data packets according to a message protocol. Responsive to the target imaging component being the PMIC, the method may also include sending the message to the target imaging component as the primary manufacturer imaging component.

A marker system includes: a first marker; and a second marker; wherein the first marker and the second marker are configured to emit light from one or more light sources coupled to the first marker and the second marker; and wherein the first marker and the second marker are configured to emit the light for detection by a camera. A method performed using a marker system includes: generating light using one or more light sources; emitting the light at a plurality of markers that are coupled to the light sources; and detecting the light emitted from the plurality of markers using a camera; wherein the act of detecting comprises using one or more filters to reduce ambient light to a level that corresponds with a noise level of the camera while allowing light emitted from the markers to be imaged by the camera.
