Abstract: A bone density measuring apparatus and a bone density imaging method capable of improving the accuracy of a bone density analysis are provided. In a state in which no subject is present, a detector detects X-rays emitted from an X-ray tube under a high tube voltage X-ray condition/a low tube voltage X-ray condition and a first gain correction map/a second gain correction map is generated (S1, S2). A detector detects the X-rays emitted from an X-ray tube and transmitted through a subject under a high tube voltage X-ray condition/a low tube voltage X-ray condition, and a high voltage image/a low voltage image captured by the detector is generated (S3). By performing a gain correction of the high voltage image using the first gain correction map, performing a gain correction of the low voltage image using the second gain correction map (S4), and performing a subtraction of the high voltage image after the gain correction and the low voltage image after the gain correction (S5), the accuracy of the bone density analysis can be improved.

Abstract: Provided is a radiation tomography apparatus that performs radiography for a series of fluoroscopic images while moving a radiation source and a radiation detecting device synchronously in opposite directions to each other and obtains a tomographic image of a subject based on the fluoroscopic images. The radiation tomography apparatus allows to preview the tomographic image obtained through the radiography immediately after completion of the radiography. A preview image for previewing a sectional image of a subject is generated besides a tomographic image for diagnosis. The preview image can be obtained through simpler computing processing. Consequently, an operator sees once the preview image displayed on a display unit prior to the tomographic image for diagnosis, thereby determining to conduct radiography again quickly.
Abstract translation: 本发明提供一种放射线断层摄影装置，其在使辐射源和放射线检测装置以相反方向同步移动的同时进行一系列透视图像的X射线照相，并且基于荧光透视图像获得被检体的断层图像。 放射线断层摄影装置允许在放射照相术完成之后立即预览通过放射照相获得的断层图像。 除了用于诊断的断层图像之外，还生成用于预览被检体的剖面图像的预览图像。 可以通过更简单的计算处理来获得预览图像。 因此，操作者在用于诊断的断层图像之前，一次看到在显示单元上显示的预览图像，从而确定快速进行放射照相。

Abstract: A borderline extraction element 15 extracts a borderline B of adjacent vertebrae from an X-ray image on which multiple vertebrae are projected connected in a line. A vertebral area setting element 17 sets a area sandwiched by the adjacent borderlines B as a vertebral area and an area number is put to the respective vertebral areas L. When the vertebral areas are erroneously set up, a setup data erase element 21 erases the data of the vertebral areas L and the area number when the borderline is corrected. The setup data are erased, so that the borderline B can be shift-corrected to any location. A vertebral area setting element 17 resets the vertebral area L based on the location of the corrected borderline. Accordingly, the respective vertebral areas L are set up to the accurate locations and only the borderline B extracted to the wrong location is shift-corrected and the vertebral areas are reset. The work-burden to the operator for setting the vertebral area can be largely lessened.

Abstract: A workstation 5 links an X-ray image conforming to the Dicom standard and exposure dose data prepared by an exposure measurement system 7 with use of information on the imaging date and time of the X-ray image conforming to the Dicom standard and information on the imaging date and time of the exposure dose data prepared by the exposure measurement system 7. This enables the workstation 5 to calculate an exposure dose corresponding to each X-ray image. Also, the workstation 5 calculates an exposure dose corresponding to each X-ray examination on the basis of data on the start time and end time of the examination received from a console part 1. An examination time and an imaging technique at each examination, data including information on a subject, and information indicating an exposure dose corresponding to the examination are configured as one piece of data and displayed on a display part 51 of the workstation 5.
