The present invention provides a radiography device for producing an X-ray image of a tooth or a structure supporting the tooth. The radiography device of the present invention includes: an X-ray source for generating X-rays; a projection unit for projecting a user control mode image to the outside as user control information for controlling the X-ray source; and a control unit including an operation unit for user operation, and controlling the X-ray source according to the user control information selected through the operation unit.

A system and method for generating X-rays are disclosed. The method may include emitting an electron beam from a cathode to a focal track of a rotating target. The method may further include deflecting the electron beam onto a first region of the focal track at a first time, and deflecting the electron beam onto a second region of the focal track at a second time. The first region of the focal track may be separated from the second region of the focal track. The method may further include generating X-rays in response to the electron beam deflected onto the first region of the focal track or onto the second region of the focal track.

A radiation imaging apparatus includes an imaging unit having sensors configured to detect radiation, and configured to output an analog signal from each sensor, an AD converter configured to, in each AD conversion period corresponding to a frame, convert the analog signals from the imaging unit into digital signals and output the digital signals as a serial data string of bits, a serial-parallel conversion unit configured to convert, into parallel data, the serial data string of the bits from the AD converter, and an alignment unit configured to perform alignment for the serial-parallel conversion unit to identify the serial data string. The alignment unit performs the alignment in at least a period between one AD conversion period and another analog-to-digital conversion period, in addition to performing the alignment before a first AD conversion period.

Certain aspects pertain to Fourier ptychographic imaging systems, devices, and methods such as, for example, high NA Fourier ptychographic imaging systems and reflective-mode NA Fourier ptychographic imaging systems.

Methods and systems are described for operating an imaging sensor, the imaging sensor including a multi-dimensional sensor. An electronic processor receives an output from the multi-dimensional sensor and transitions the imaging sensor from the low-power state into a ready state in response to a determination by the electronic processor, based on the output from the multi-dimensional sensor, that a first state transition criteria is satisfied and transitions the imaging sensor from the ready state into an armed state in response to a determination that a second state transition criteria is satisfied. In some implementations, the electronic processor operates the imaging sensor to capture image data only when operating in the armed state and prevents the imaging system from transitioning from the low-power state directly into the armed state.

A medical scan image analysis system is operable to receive a plurality of medical scans that represent a three-dimensional anatomical region and include a plurality of cross-sectional image slices. A plurality of three-dimensional subregions corresponding to each of the plurality of medical scans are generated by selecting a proper subset of the plurality of cross-sectional image slices from each medical scan, and by further selecting a two-dimensional subregion from each proper subset of cross-sectional image slices. A learning algorithm is performed on the plurality of three-dimensional subregions to generate a fully convolutional neural network. Inference data corresponding to a new medical scan received via the network is generated by performing an inference algorithm on the new medical scan by utilizing the fully convolutional neural network. An inferred abnormality is identified in the new medical scan based on the inference data.

A medical scan comparison system is operable to receive a medical scan via a network and to generate similar scan data. The similar scan data includes a subset of medical scans from a medical scan database and is generated by performing an abnormality similarity function to determine that a set of abnormalities included in the subset of medical scans compare favorably to an abnormality identified in the medical scan. At least one cross-sectional image is selected from each medical scan of the subset of medical scans for display on a display device associated with a user of the medical scan comparison system in conjunction with the medical scan.

A radiographic detector acquires a first partial exposed image signal during an image readout of each of the rows of photosensors, one row at a time. A first scan of each row includes measuring the charge delivered to each cell of the rows, including some rows having partial charge and other rows having full charge, and obtaining a first null image signal during the scan. A second scan includes measuring remaining charge delivered to those rows having partial charge. The null image signal data is subtracted from a sum of the first two scans.

Provided is a technique that reduces patterning defects of data lines in an imaging panel and drain electrodes in thin film transistors without lowering the aperture ratio of the imaging panel. The imaging panel captures scintillation light, which are X-rays that have passed through a specimen and been converted by a scintillator. The imaging panel includes a plurality of gate lines and a plurality of data lines. The imaging panel includes, in each of the pixels, a conversion element that converts scintillation light to electric charge, and a thin film transistor connected to the gate line, data line, and conversion element. A drain electrode of the thin film transistor is formed such that edges of the drain electrode near the data line are more inside the pixel than edges of the conversion element near the data line.

The present disclosure is for minimizing the problem of AED sensor malfunction, and comprises: a panel having a plurality of sensing elements for sensing an X-ray, and converting an X-ray into an electrical signal; an AED sensor for sensing an X-ray; and a main control unit for obtaining image data by reading out the charge of the panel when an X-ray is sensed by the AED sensor, wherein the main control unit may determine whether or not reading out is to be performed on the basis of the acceleration of the panel even when the AED sensor senses an X-ray.
