Problems solved by technology

In the warping process, since the alignment is generally performed according to the spatial density change caused by the structure in the lung field, it is necessary to faithfully (uniformly) reproduce the density of the structure for all frames of images. The difference in the output of each pixel (therefore, it is necessary to correct the difference by performing various correction processes such as offset (offset) correction processing, gain correction processing, defective screen correction processing, and hysteresis correction processing), and the correction process takes time. In addition, in order to perform high-precision warping processing, the higher the precision, the more high-resolution images are required, so a detector with a small pixel size is required, which increases the data capacity of each frame of image and becomes the entire data to be processed. Large increase in capacity
Therefore, hardware such as a large-capacity memory and a high-speed processing CPU are required, and the processing time is also increased.

no. 1 Embodiment approach

[0060] figure 1 It is a diagram showing the overall configuration of the diagnosis support information generating system 100 according to the first embodiment of the present invention.

[0061] figure 1 The illustrated imaging rooms R1 to R3 are rooms for performing dynamic imaging or still image imaging of the subject by irradiating a subject (that is, the imaging part of the patient) that is a part of the patient's body with radiation.

[0062] Dynamic photography refers to photography that acquires multiple images (ie, continuous photography) by continuously irradiating a subject with radiation such as X-rays in a pulsed manner. Through dynamic photography, for example, the morphological changes of lung expansion and contraction accompanying breathing movement, and the pulsation of the heart, etc., have periodic dynamics of the subject. A series of images obtained by this continuous shooting are called moving images. In addition, a plurality of images constituting a moving imag...

no. 2 Embodiment approach

[0270] Next, the second embodiment of the present invention will be described.

[0271] First, the structure will be explained.

[0272] Figure 17 The overall configuration of the diagnosis support information generating system 300 in the second embodiment is shown. The diagnosis assistance information generation system 300 is a system that uses the analysis server 30 of the analysis center to analyze moving images taken in small-scale facilities such as private hospitals and clinics, and provides the analysis results to the small-scale facilities. As explained in the first embodiment, when the winding process may not be performed, it is not necessary to consider the pixel size of the FPD and the dynamic range of each pixel when performing the analysis process. Therefore, regardless of the type of FPD used in each facility, analysis processing can be provided in an open system as described below.

[0273] Such as Figure 17 As shown, the reception device 20 is installed in the rec...

Abstract

The invention concerns a dynamic diagnosis support information generation system which reduces the processing time in the analysis of a dynamic image without requiring use of hardware such as a high-capacity memory and high-speed CPU. Based on the dynamic diagnosis support informatioin generation system concerned in the invention, in the analysis of the WS 8 for analysis, the process of warping is not provided among frame images. Instead, pixels showing the outputs of the detecting elements at the same position of the FPD 9a are associated among a plurality of frame images , and the feature value of a moving subject is calculated.

Description

Technical field [0001] The invention relates to a dynamic diagnosis auxiliary information generating system. Background technique [0002] In recent years, it has been proposed to use FPD (Flat Panel Detector) corresponding to the moving image to perform dynamic photography of the subject. Based on a series of frame images obtained through the dynamic photography, the feature quantity related to the movement is calculated, and This is a technique to provide physicians with diagnostic assistance information for early diagnosis (for example, refer to Patent Documents 1 and 2). [0003] [Patent Document 1] JP 2003-298939 A [0004] [Patent Document 2] JP 2009-153678 A [0005] Although Patent Documents 1 and 2 are technologies related to diagnostic auxiliary information related to chest breathing, when analyzing characteristic quantities related to chest breathing motion, such as ventilation volume and blood flow, it is necessary to Since multiple frames of images are compared with eac...
