    Abstract: An apparatus includes an image analysis unit arranged to extract, from the medical image, brightness intensities of a first body lumen region of the medical image and brightness intensities of a second body lumen region of the medical image; and a measuring unit arranged to calculate a first body lumen value and a second body lumen value, each of the first body lumen value and a second body lumen value being calculated as a predetermined linear combination of the brightness intensities of the corresponding first body lumen region and second body lumen region, and to compare the first body lumen value with the second body lumen value.

    Abstract: An X-ray imaging apparatus displays a bone or soft tissue image of an X-ray image, which corresponds to a region selected by a user, thereby reducing a diagnosis time. In addition, an X-ray imaging system transmits a first energy X-ray image and a second energy X-ray image to a central image management system, and a user control apparatus receives the images from the central image management system and displays a bone or soft tissue image corresponding to the selected region, thereby reducing burden imposed on server capacity of the central image management system as well as reducing a diagnosis time.

    Abstract translation: X射线成像装置显示与用户选择的区域对应的X射线图像的骨骼或软组织图像，从而减少诊断时间。 此外，X射线成像系统将第一能量X射线图像和第二能量X射线图像发送到中央图像管理系统，并且用户控制装置从中央图像管理系统接收图像并显示骨骼 或软组织图像，从而减轻对中央图像管理系统的服务器容量的负担，并减少诊断时间。

    Abstract: An X-ray imaging apparatus and control method thereof precisely designates an imaging region and reduces user fatigue by designating a segmentation imaging region using an image of a target object captured by a camera and automatically controlling an X-ray generator according to the designated segmentation imaging region. The X-ray imaging apparatus includes an X-ray generator to perform X-ray imaging of a target object by generating and irradiating X-rays, an image capturer to capture an image of the target object, an image display to display the image captured by the image capturer, an input part to receive designation of a region for which segmentation imaging is to be performed on the image displayed on the image display, and a controller to control the X-ray generator to perform segmentation imaging with respect to the designated region.

    Abstract: A method for calibrating an imaging device comprising a photon counting detector (PCD), the method comprising: providing (i) an X-ray source configured to emit an X-ray beam, (ii) a first detector array configured to be in alignment with the X-ray beam, wherein the first detector array comprises a plurality of energy integrating detectors (EID) for detecting the X-ray beam emitted by the X-ray source, and (iii) a second detector array configured to be in alignment with the X-ray beam, wherein the second detector array comprises a plurality of photo counting detectors (PCD) for detecting the X-ray beam emitted by the X-ray source; detecting an X-ray beam passed through an object to be scanned with the plurality of energy integrating detectors (EID); recording the X-ray beam passed through the object to be scanned and detected by the plurality of energy integrating detectors (EID) as a first data set; detecting an X-ray beam passed through the object to be scanned with the plurality of photo counting detectors (PCD); recording the X-ray beam passed through the object to be scanned and detected by the plurality of photo counting detectors (PCD) as a second data set; generating a mathematical model from the first data set and the second data set so as to derive an attenuation factor; and applying the attenuation factor to the second data set to calibrate the imaging device.
