An X-ray imaging system includes a digital X-ray detector configured to acquire X-ray image data without communication from a source controller and to send the X-ray image data to a portable detector control device for processing and image preview. The source controller is configured to command X-ray emissions of X-rays from an X-ray radiation source for image exposures.

X-ray system and method with digital image acquisition

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

The present disclosure is directed towards a method of changing wireless communication channels in a connected host and client system. For example, in one embodiment, the link quality of a connection is monitored by the host or the client. If the connection has a link quality below a predetermined threshold but remains intact, a channel switch request is sent, synchronization packages are exchanged between the host and client on the current channel, the channel of the system is changed to a new channel, and the system resumes communications on the new channel.

Wireless communication in a medical imaging or monitoring system

A method for processing X-ray image data includes exposing a digital detector to X-ray radiation. The method also includes sampling data via the digital detector including X-ray image data and offset image data. The method further includes calculating an average offset image without prior knowledge of a total number of offset image frames sampled.

X-ray system and method for processing image data

A method of fabricating a portable x-ray detector includes coupling a gravity sensor to the portable x-ray detector and coupling a processor to the gravity sensor. The processor is programmed to receive an input from the gravity sensor, determine a physical orientation of the portable x-ray detector based on the received input, and generate an indication to reposition the portable x-ray detector. A portable detector and an imaging system including the portable detector are also provided.

Position sensing device for a portable detection device

An X-ray imaging method includes in a digital X-ray detector including an array of discrete picture elements each including a photodiode and a transistor, applying a first voltage to the transistors of the discrete picture elements. The method also includes preparing for acquisition of X-ray image data by sampling data from the discrete picture elements while applying a second voltage to the transistors of the discrete picture elements not then being sampled, the second voltage being more negative than the first voltage. The method further includes receiving X-ray radiation on the detector from a source. The method yet further includes sampling X-ray image data from the discrete picture elements while applying the second voltage to the transistors of the discrete picture elements not then being sampled.

X-ray system and method for sampling image data

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.

Energy detector and related apparatus

An X-ray imaging method includes performing an X-ray exposure via an X-ray radiation source responsive to a source controller. The method also includes sampling X-ray image data via a digital detector without communication of timing signals from the source controller. The method further includes combining the sampled X-ray image data of at least one imaging frame or two or more imaging frames with at least one of the frames spanning a duration in which the exposure occurred, to produce X-ray image data capable of being reconstructed into a user-viewable image.

The anti-scatter grid is configured to absorb a plurality of scattered x-rays impinging on the anti-scatter grid while substantially allowing un-scattered x-rays to pass through the anti-scatter grid. The x-ray conversion layer is configured to convert an x-ray into visible light or an electronic signal. The flat panel x-ray detector is fixed relative to the anti-scatter grid such that the anti-scatter grid remains stationary relative to the flat panel x-ray detector during operation of the x-ray detector.

Digital x-ray detector assembly

The effects of electromagnetic interference (EMI) on X-ray image data is corrected by characterizing the EMI and processing the image data to subtract the EMI effects from the image data. The X-ray image data, along with offset data, are collected in a conventional manner, affected by EMI if present, and EMI-characterizing data is immediately collected thereafter by disabling rows of a digital detector (FET off). The EMI-characterizing data, then, is not affected by the presence of image data, and can be used to characterize the amplitude and frequency of the EMI. The EMI-characterizing data is assured of being in phase with the collected image and offset data due to its collection in the same image acquisition sequence immediately following the collection of image and offset data. Artifacts due to the presence of EMI are thus eliminated from reconstructed images based upon the corrected data.
