摘要： Before a CT scan for a patient, a model that shows transmission lengths of the patient at rotation angles of an X-ray source is stored in a memory. At the CT scan, X-ray tube currents are controlled according to the transmission lengths at the rotation angles in order to apply X-rays to the patient. The three-dimensional model is homogenous and its material is similar to that of the patient's body, and transmission lengths of the three-dimensional model are converted into those of the patient. The model is acquired by a scannography in a single direction or a CT helical scanning with a small X-ray dose. This reduces the X-ray dose applied to the patient.

摘要： In an X-ray CT device, the scan conditions of the device are set, a three-dimensional X-ray passage length model of the body being examined is generated from a scanogram image of the body, the control pattern of the tube current is automatically set on the basis of the scan conditions and the three-dimensional passage length model, and the dose which will be given will be calculated and displayed on the basis of the control pattern of the tube current, and three-dimensional CT value model data of the body generated on the basis of a standard human body. The scanogram image of the body and the control pattern of the tube current are displayed next to each other or overlap to allow an operator to edit the control pattern while viewing the body, so that a suitable tube current can be set.

摘要： The liquid crystal display device (100) according to the present invention performs display in a stereoscopic display mode. In each of the plurality of pixels in the liquid crystal display device (100), left-eye image data and right-eye image data are alternately written every two successive vertical scanning periods. Each of the plurality of pixels exhibits the same polarity over the two vertical scanning periods in which left-eye image data is written, and exhibits the same polarity over the two vertical scanning periods in which the right-eye image data is written. Accordingly, the liquid crystal display device (100) performs stereoscopic display with suppressed display unevenness.

摘要： Radiation is generated toward a patient. A radiographic region of the radiation covers a predetermined field-of-view. Both of a stereotactic radiation producing filter and a radiographic radiation producing filter are transported in such a way that the stereotactic radiation producing filter and the radiographic radiation producing filter sequentially intercept the beam axis between the patient and a generation position for the radiation. When the stereotactic radiation producing filter is located on the beam axis, it forms the radiation into radiation required for stereotactic radiosurgery. When the radiographic radiation producing filter is located on the beam axis, it forms the radiation into radiation required for radioscopy. Radiation present within the radiographic region is detected with employment of a radiation detecting unit positioned opposite to the generation position of the radiation with respect to the patient. The radiation is generated when the stereotactic radiation producing filter is located on the beam axis and the radiographic radiation producing filter is located on the beam axis.
