摘要： An image processing system according to an embodiment includes a first image creating unit, a second image creating unit, and a display controller. The first image creating unit creates a first image by performing a rendering processing on volume data which is three-dimensional medical image data. The second image creating unit creates a second image having a different stereoscopic effect from the first image by performing the rendering processing on the volume data. The display controller that controls to display the first image and the second image in a designated region that is designated in a display surface of a display unit and a background region other than the designated region, respectively.

摘要： An X-ray CT apparatus has an irradiate unit, a determination unit, and a displaying unit. The irradiate unit irradiates an X-ray. The determination unit determinates a tube current value modulation to extend to a body axis direction in a predetermined rotation angle of the irradiate unit based on an index value to show a dispersion of CT values in required area in a reconstructed image, and a scan condition. The displaying unit aligns and displays an image of the index value and an image of the tube current value modulation on an image used for positioning.

摘要： An X-ray CT apparatus detects a predetermined characteristic wave from each electrocardiographic waveform acquired from an electrocardiograph, predicts intervals with which the characteristic wave appears based on appearance times of the detected predetermined characteristic wave in each electrocardiographic waveform, and determines an X-ray irradiation start time based on the predicted interval time. After an instruction to start collection of X-ray intensity distribution data is received, if an appearance interval of a detected predetermined characteristic wave is within an acceptable normal-heartbeat range, it is determined as a normal heartbeat. If the appearance interval of the detected predetermined characteristic wave is outside the acceptable normal-heartbeat range, it is determined as an abnormal heartbeat. During a period after receiving the instruction to start the collection until reaching a time of starting the collection of X-ray detection information, when determined as an abnormal heartbeat, an X-ray irradiation start time is recalculated, and then determined.

摘要： In an X-ray CT scanner having an X-ray tube which applies an X-ray spreading in a body axis direction of a subject, and an X-ray detector having a wide imaging range which detects the X-ray passed through the subject and converts the detected X-ray into an electric signal, a desired image creation time is set by use of a specific CT value curve in a console input unit before scanning with the X-ray. After the scanning, data of the CT value change curve is generated based on the obtained projection data. An image creation range in the generated change curve is determined based on an image creation range set in the console input unit, and the image creation is performed in the image creation unit based on the determined image creation time.
