A cassette for X-ray imaging includes a cassette body storing an X-ray detector. Three reflective optical sensors are arranged on an upper end side of a rear surface, which is opposite to a detection surface, of the cassette body. An X-ray detection device for supine-posture imaging has a table. The X-ray detection device includes a tray to which the cassette is loaded. Markers for identifying a loading orientation of the cassette are attached to the tray. The reflective optical sensors read out the markers and detect the loading orientation of the cassette.

A method is provided which is capable of efficiently taking most of a precious sample into an extraction vessel without wasting when the sample is extracted from a collection section of a sampling rod. The method includes the steps of collecting a sample using a sampling rod formed of a rod body and a collection section attached to the rod body, inserting the sampling rod into the extraction vessel, placing the rod body in a gap formed in a grappling hook section which is disposed in an insertion path of the sampling rod, the gap having a width smaller than a diameter of the collection section and being capable of receiving the rod body, withdrawing the rod body with the rod body being placed in the gap and detaching the collection section from the rod body by hooking the collection section to the grappling hook section.

A supporting/moving section for supporting and moving a device to predetermined positions at which radiation imaging is performed is prepared. An operating portion is provided for manipulating the movement of the device supported by the supporting/moving means. A detecting section outputs detection signals, which are obtained by detecting external forces which are applied to the operating portion. A control section controls the supporting/moving means to move the device such that the movement tracks target values for movement, which are determined from the detection signals. During manipulation of the operating portion, a unique oscillation frequency measuring section executes measurements to obtain a unique oscillation frequency of the device. A unique oscillation attenuating section attenuates signal components, which are included in control signals output by the control means to control the supporting/moving means and cause the movement of the device to fluctuate at the unique oscillation frequency, in real time.

Image data of a test pattern is transmitted to an image processor and image processing is effected by the image processor based on the test pattern. The image outputted (the results of the image processing) from this test pattern image processing and the original image are compared to each other. If they are different, the image processing by the current image processor is judged to be abnormal. In this case, the image processor (hardware process) is switched promptly and automatically to be emulated by an auto set-up engine (software process). Further, in the image processor section, ordinarily, three frame memories are used to effect processes including reading of image data, image processing, and outputting of image data at the same time and in parallel. Image processing can be switched in such a manner that when any one of the frame memories is judged to be abnormal, the two remaining frame memories judged as normal are used to execute image processing.

Image processing device

A test pattern which has an outputted image obtained by said image processing executing normal image processing is used to self-judge an image processor. Namely, image data of the above described test pattern is transmitted to the image processor and image processing is effected by the image processor. The image outputted (the results of the image processing) from this image processing and the original image are compared to each other. When they do not correspond to each other, the image processing by the current image processor is judged to be abnormal. In this case, the image processing using the image processor (hard ware process) is switched promptly and automatically to be emulated by an auto set-up engine (soft ware process). Further, in the image processor section, ordinarily, all of the three frame memories are used to effect processes including reading of image data, image processing, and outputting of image data at the same time and in parallel. For example, image processing is switched in such a manner that when any one of the frame memories is judged to be abnormal, two remaining frame memories which are judged to be normal are used to execute image processing.

At least one mode of a group of modes consisting of a photoelectric conversion/accumulation, transfer, hold and read-out mode adapted for image information is controlled by a basic clock signal generated by a central processing unit for driving and controlling an accumulation type photoelectric conversion element. The frequency of the basic clock signal in the read-out mode is made lower than the frequencies of the basic clock signals in the conversion/accumulation, transfer and hold modes. Since the generation and frequency of the basic clock signal are controlled by the software of the CPU provided with no pulse oscillator, the construction of the hardware of the system to which this invention is applied can be simplified. In addition, since the read-out process of the data of the image sensor is performed for every picture element of the entire picture surface and the characteristic value operation with respect to the data of every picture element, the total processing time can be reduced.
