Method and system for generating panoramic radiographic images by merging contributions from panoramic images obtained with respect to a plurality of layers, wherein the method provides for performing a so-called Multipan image acquisition and for identifying the image contributions of the various panoramic images that present the best focus of details reproduced therein and for combining said contributions of said images into a fused panoramic image by applying a wavelet decomposition transform to said images for identifying said contributions of said images that represent image details with the best focus and reconstructing from these the fused image by applying the inverse wavelet transform. According to an advantageous variant, the method provides for a step of aligning the horizontal magnification of the panoramic images prior to applying the wavelet transform for decomposition and reconstruction. The invention also relates to a system for implementing said method, comprising a radiographic device and a processing unit in which a program is loaded and from which said program is executable, said program comprising instructions for the processor of said processing unit such that, when said instructions are executed, the processing unit is capable of performing the steps of the method that is the subject of the present invention.

The ray detection device for the LNG low-temperature storage tank comprises ray detection equipment and is characterized by further comprising a bearing frame, rollers are arranged at the upper end of the bearing frame, a mounting frame is connected to the rollers, hooks are arranged at the lower end of the mounting frame, a connecting hanging ring is hung on the hooks, a loading structure is arranged below the connecting hanging ring, and the loading structure is connected with the mounting frame. Combined grooves are formed in the two sides of the loading structure, and ray detection equipment is placed on the loading structure. The rollers drive the bearing frames to move automatically, the multiple sections of bearing frames can be spliced into a continuous track, continuous detection of circular seams is achieved, frequent manual movement of equipment is not needed, a single person can control the multiple sections of detection devices, the detection speed is increased by more than 50%, the device is suitable for batch detection of large storage tanks, and the detection efficiency is improved; the loading structure fixes the ray equipment through the fixing plate, the turnover plate and the limiting rod, the supporting legs and the universal wheels are tightly attached to the side wall of the storage tank, negative film blurring or digital image distortion caused by shaking is avoided, and the detection accuracy is improved to 99% or above.

To provide a mechanism which can perform irradiation stop control of radiation from a radiation generation device with high accuracy.SOLUTION: A radiographic device includes: a control part 200 including a dose calculation part 126 for calculating an accumulation reached dose of radiation detected by a sensor part 121 from the start of imaging, a timer part 125 for timing irradiation time of radiation from predetermined timing, a threshold determination part 124 for determining an irradiation stop threshold based on the irradiation time, and a threshold determination part 122 for transmitting an irradiation stop signal so as to stop irradiation of radiation with respect to a radiation generating device 110 when the accumulation reached dose becomes the irradiation stop threshold; and the sensor part 121 for detecting the radiation which has entered from the radiation generating device 110. The threshold determination part 122 allows the timer part 125 to start timing of the irradiation time when the dose calculation part 126 performs the calculation and finds out that the accumulation reached dose from the start of imaging has reached a predetermined amount.SELECTED DRAWING: Figure 1
