Abstract: The present invention relates to optimizing values for scan parameters for a scan of an object. An object specific exposure time is determined based on a maximal required value of a z-dependent tube current by exposure time product along a z-axis of the object and a maximal available tube current value of a tube used for the scan of the object (140). The maximal available tube current value depends on a tube voltage and maximal electric power of the tube at given focal spot area (110) and the z-dependent tube current by exposure time product profile is based on a dose index value or a pixel noise index value for the scan of the object, the tube voltage, and a z-dependent object size along the z-axis (120). The object specific exposure time is used for determining values of the scan parameters for the scan of the object (150).

Abstract: An X-ray fluoroscopic imaging apparatus includes first slide mechanism is disposed at a lower end of a support column, and a second slide mechanism is disposed at an upper end of the support column. When an operation unit has received an instruction, a controller performs a first mode in which the X-ray generator is moved in the predetermined direction by operating the second slide mechanism to move an X-ray support arm in the predetermined direction with respect to the upper end of the support column. Thereafter, the controller performs a second mode of operating the first slide mechanism to move the lower end of the support column at a predetermined first speed in the predetermined direction with respect to a support column support arm, while operating the second slide mechanism to move the X-ray support arm at a second speed smaller than the first speed in an opposite direction.

Abstract: At least two first offset images having different accumulation times are acquired in a state in which radiation is not emitted. A pixel signal is read in an accumulation time shorter than that of a plurality of first offset images or using binning reading in a state in which the radiation is not emitted to acquire a second offset image. A reference image is acquired by reading the pixel signal using the same reading method as that used for the second offset image and in a state in which gates of the pixels are turned off. A difference between the two first offset images having different accumulation times is calculated to acquire a first dark current distribution image. A difference between the second offset image and the reference image is calculated to acquire a second dark current distribution image.

Abstract: In order to perform a setting of whether or not an input of an imaging failure reason at the time of an imaging failure is necessary, a check box 8j on whether or not the input of the imaging failure reason is necessary is displayed on a screen. When an operation to input a check mark in the check box 8j is performed, it is set that the input of the imaging failure reason is necessary. When an operation to remove the check mark from the check box 8j is performed, it is set that the input of the imaging failure reason is unnecessary. When it is set that the input of the imaging failure reason is necessary, a screen for inputting the imaging failure reason is displayed. When it is set that the input of the imaging failure reason is unnecessary, a screen for inputting the imaging failure reason is skipped. As a result, when the input of the imaging failure reason is unnecessary, the input operation is automatically skipped, reducing the burden on the operator.
