摘要:
Disclosed in an x-ray imaging device, which uses a Talbot-Lau interferometer, eliminates the effects on image quality of a reconstructed image that arises in such cases as when the direction of a multi-slit or each lattice slit is altered and imaging is performed, and provides reconstructed images favorable for diagnosis. When a plurality of moire images imaged with an imaging subject loaded onto a imaging subject stand (13) and a plurality of moire images imaged without the imaging subject are input, a control unit (51) of a controller (5) corrects signal value differences arising from variations in x-ray strength during imaging respectively between the plurality of moire images with the imaging subject and between the plurality of moire images without the imaging subject, and respectively creates a reconstructed image with the imaging subject and a reconstructed image without the imaging subject. Then, the control unit (51) creates a reconstructed image of the imaging subject for diagnosis by correcting, on the basis of the reconstructed image without the imaging subject, image unevenness in the reconstructed image with the imaging subject caused by heterogeneity in light distribution caused by the angle of rotation of the multi-slit.

摘要:
The apparatus includes: an X-ray source a multi slits element a first grating; a second grating; a driving section; a subject placing plate: and an X-ray detector, in which conversion elements to convert intensities of X-rays received thereby to electric signals, are arranged in a two-dimensional pattern so as to read the electric signals as image signals. The driving section moves the multi slits element relative to both the first grating and the second grating in a first direction orthogonal to a second direction of irradiating the X-rays, so that the X-ray detector repeats a processing for reading the electric signals converted from the intensities of X-rays received thereby, every time when the multi slits element moves at predetermined intervals so as to acquire the image signals representing Moire images captured at the predetermined intervals.

A temperature and humidity control apparatus includes a humidity control section for controlling humidity when a flow rate of a low temperature fluid in a cooling dehumidifier composed of a heat exchanger is determined; a heater control section for controlling temperature when a flow rate of a high temperature fluid in a heater; and a predicting device for predicting an amount of temperature change caused by an operation of the cooling dehumidifier. The amount of predicted temperature change is canceled when the flow rate of the high temperature fluid in the heater is determined in the heater control section, and the flow rate of the high temperature fluid in the heater is determined so that the setting temperature can be realized.
摘要:
There is described a radiological image capturing system, which makes it possible to obtain an accurate radiological image, irrespective of the position of the diagnosis object in the thickness direction of the subject. The system includes a radiographing apparatus that output radiological image data, based on the radial rays detected by the image detecting device, an image processing apparatus that applies a degraded image restoration processing to the radiological image data and a fixing member onto which the subject is fixed. The subject is positioned at such a position that a ratio of blurs between the first radiological image radiographed at a first position and the second radiological image radiographed at a second position, which is apart from the image detecting device by a distance farther than that of the first position, is reduced to a value to such an extent that a blur difference between them can be ignored.
