no. 1 Embodiment approach 〉
[0039] Hereinafter, the first embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the scope of the invention is not limited to the illustrated examples.
[0040] (Configuration of chest diagnostic assistance system 100)
[0041] First, the configuration will be described.
[0042] figure 1 The overall configuration of the chest diagnosis assistance system 100 in the present embodiment is shown.
[0043] like figure 1 As shown, the chest diagnosis assistance system 100 is configured such that an imaging device 1 and an imaging console 2 are connected by a communication cable or the like, and the imaging console 2 and the diagnostic console 3 communicate via a LAN (Local Area Network) or the like. Network NT connection. Each device constituting the chest diagnosis assistance system 100 conforms to the DICOM (Digital Image and Communication in Medicine) standard, and communication between the devices is perfor...
no. 2 Embodiment approach ＞
[0124] Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.
[0125] Here, conventionally, in radiography of a chest still image, as described in, for example, Japanese Patent Laid-Open No. 10-98587 (Public Document 1), a scattered-ray removal grid (hereinafter referred to as grid) for removing scattered rays is used. ) to shoot.
[0126] In addition, in recent years, as described in Japanese Unexamined Patent Application Publication No. 2005-312775 (Public Document 2), it has been proposed to perform dynamic imaging of the chest using a radiationdetector such as an FPD (flat paneldetector), and use it for diagnosis. However, in such a system for moving images, as in still image capturing, images are captured using a grid.
[0127] In Known Document 2, in order to reduce the exposuredose of the subject during dynamic shooting in ...

Abstract
Provided is a thoracic diagnosis assistance system. The system includes, an imaging unit, an extracting unit, a region dividing unit, an analysis unit and a display unit. The extraction unit extracts a lung field region from the plurality of successive image frames generated by the imaging unit. The region dividing unit divides the lung field region extracted by the extraction unit into a plurality of sub-regions and correlates the sub-regions among the plurality of image frames. The analysis unit performs an analysis of the sub-regions to calculate an inspiratory feature quantity and an expiratory feature quantity and to calculate a value of a ratio of the calculated inspiratory feature quantity to expiratory feature quantity and creates a histogram of the calculated ratio value. The display unit displays the histogram.
Description
technical field [0001] The present invention relates to chest diagnostic assistance systems and procedures. Background technique [0002] For the conventional radiographic still image capturing and diagnosis of the breast using film / screen and depleting phosphor plate, a semiconductorimage sensor such as FPD (flat paneldetector) is used to capture a moving image of the breast and try to apply it to diagnosis. Specifically, utilizing the rapidity of the responsiveness of the reading and erasing of image data of the semiconductorimage sensor, and the timing of reading and erasing of the semiconductorimage sensor, pulse-shaped radiation is continuously irradiated from the radiation source for 1 second. Chung took multiple shots to capture the movement of the chest. By sequentially displaying a series of a plurality of images acquired by photographing, the physician can observe a series of movements of the chest accompanied by breathing motion, heart beat, and the like. ...
