Abstract:
An electronic apparatus mounted on a vehicle is provided. The electronic apparatus includes an output unit configured to output driving information on the vehicle, a sensor configured to sense a gaze of a user in the vehicle, and a processor configured to, in response to a position on a plane of the sensed gaze being included in a specific region, control the output unit to output the driving information.
Abstract:
Disclosed is a computed tomography (CT) system which includes a rotatable collimator. The CT system includes a gantry. The gantry includes an X-ray source that generates X-rays, a collimator that is provided inside the X-ray source to be rotatable and that limits an irradiation area of the X-rays generated by the X-ray source, and an X-ray detector that is provided at a side portion of the X-ray source.
Abstract:
A computed tomography (CT) apparatus includes a reconstruction unit which reconstructs a first CT image corresponding to a field of view (FOV) by using a first sinogram acquired by a CT scan of an object; and a correction unit which acquires a second sinogram by performing forward projection on the first CT image and acquires a second CT image by using the second sinogram and a third sinogram representing a portion of the object that is not included in the FOV. Thus, the CT apparatus reduces generation of image errors to thereby provide a high-quality reconstructed CT image.
Abstract:
An image processing method of an image processing apparatus includes projecting centers of pixels of a pixel grid onto a preset common axis, mapping a boundary of a detector cell comprised in the detection unit on the preset common axis, and determining a detector value based on the projecting the centers of the pixels onto the preset common axis and the mapping the boundary of the detector cell on the preset common axis.
Abstract:
A medical imaging apparatus includes a data acquirer configured to acquire measured data acquired by detecting an X-ray transmitted by an X-ray source to an object, and an image processor configured to acquire an initial image based on the measured data, alternately estimate region of interest (ROI)-outside measured data and ROI-inside measured data based on the measured data and the initial image, and acquire a reconstructed image based on the ROI-inside measured data.
Abstract:
A chip mountable on a customer replaceable unit monitoring memory (CRUM) unit used in an image forming job includes a central processing unit (CPU) with an operating system (OS) thereof, which is separate from an OS of the image forming apparatus, to perform at least one of authentication and cryptographic data communication with a main body of an image forming apparatus by executing one cryptographic algorithm corresponding to a set state from among a plurality of pre-provided cryptographic algorithms, using the OS thereof. The security of a unit on which the chip is mounted can thereby be reinforced and random changes of data of the unit can be prevented.
Abstract:
A developer of an image-forming apparatus includes a photoconductor, a housing comprising a waste toner container in which waste toner removed from the photoconductor is contained, and a recessed portion depressed downwardly in a center portion of an upper wall of the waste toner container, the center portion corresponding to a center portion of the photoconductor in a lengthwise direction to move toner away from the center portion.
