A radiographic-image processing apparatus that can accurately remove striated artifacts superimposed onto image data taken by an FPD radiographic imaging device includes: a partitioning section that partitions a region, in which image data taken by a radiographic imaging device is arranged two-dimensionally, into segments; a mean-value computation section that computes mean values from the image data along the same scanning line in each segment; an edge compression section that compresses mean-value differentials in boundary regions between the imaged subject and the surroundings thereof; a filtering section that applies an adaptive filter to the differential-compressed profile; and a correction-data creation section that creates correction data on the basis of each datum in the adaptive-filtered profile. Image data in which noise is removed is generated by subtracting corresponding correction data from the image data.

In a radiation image capturing system, prior to radiation image capturing operation, the radiation image capturing apparatus repeats on an alternate basis, a step of reading leak data and a step of resetting each of the radiation detection elements, wherein the step of reading leak data is performed by turning off all switch units, allowing a reading circuit to perform cyclic reading operations under this condition and converting electric charge leaking out of radiation detection elements through the switch units into the leak data, thereby detecting a start of irradiation based on the leak data having been read out. The image processing apparatus analyzes a profile of image data along the extension of signal lines of the radiation image capturing apparatus, and identifies a range of the image data where a defect has occurred, whereby the image data in the identified range is corrected.

A dynamic image, of a quality required for diagnosis that does not increase the radiation dosage of a person being imaged, can be captured by a dynamic imaging system that includes an imaging console which has a control unit. The control unit analyzes at least one of the frame images captured at an initial state of dynamic imaging, calculates an index indicating the quality of the image, and calculates, by using the calculated index, an upper limit frame rate fsuch that the index indicating the quality of the frame image captured by the dynamic imaging is below a determined reference value. The frame rate used for dynamic imaging is determined according to the calculated upper limit frame rate fand a lower limit frame rate frequired to diagnose the dynamic state of the imaged region. An imaging device may image the person at the determined frame rate.

At the detection of an occurrence of a sheet feeder jam, in a case where media in the course of being printed on one face exist, printing this one face is continued, and this medium is inserted into the duplex printing unit. After this, relief of the sheet feeder jam is requested, and change in the duplex printing unit is monitored. In the case where there is no change in the duplex printing unit, after the printing process is re-started, re-use of the medium is allowed.
