Problems solved by technology

[0003] Therefore, it is possible to take a moving image of the object area including the area to be diagnosed by using a semiconductor image sensor such as an FPD (flat panel detector), so attempts to implement it cannot be implemented in conventional still image imaging and diagnosis based on X-ray imaging. Pathological analysis and diagnosis resulting from activity analysis of the diagnosis target area, etc.

no. 1 Embodiment approach

[0091] Hereinafter, a radiographic video imaging system according to a first embodiment of the present invention will be described.

[0092]

[0093] The radiographic imaging system according to the first embodiment takes a human body or an animal body as a subject, and captures radiographic images in response to a situation in which the physical state of an object region of the subject changes periodically with time.

[0094] figure 1 It is a diagram showing the overall configuration of the radiographic video imaging system according to the first embodiment. Such as figure 1 As shown, the radiographic imaging system 100 includes an imaging device 1 , an imaging control device 2 (console for imaging), an image processing device 3 (console for diagnosis), and an electrocardiograph 4 . The imaging device 1 and the electrocardiograph 4 are connected to the imaging control device 2 via a communication cable or the like, and the imaging control device 2 and the image processi...

no. 2 Embodiment approach

[0277] Dynamic images used for blood flow diagnosis are supposed to be captured for about 30 seconds equivalent to the number of breaths, so if the heart rate is 60 beats / min, 30 cycles are captured in one dynamic image capture. Therefore, when analyzing the total time TA of moving images, if the first and second thumbnail images SG1 and SG2 are generated and displayed in units of one cycle, the number of thumbnail images will also reach 30. As a result, the number of thumbnail images SG increases, and the size of each thumbnail image SG on the display screen becomes smaller, making it difficult to grasp abnormalities in the blood flow.

[0278] Therefore, in the second embodiment, the thumbnail images SG can be grouped and displayed hierarchically according to the similarity SI between the thumbnail images SG.

[0279] Figure 23 It is a diagram showing the functional configuration of a control unit 31A used in the image processing device 3A configured as the second embodime...

no. 3 Embodiment approach

[0304] Figure 25 It is a diagram showing the functional configuration of the control unit 31B used in the image processing device 3B configured as the third embodiment of the present invention. This control unit 31B is used as the control unit 31B in the image processing device 3 of the first embodiment (see image 3 ) instead. The difference from the first embodiment is that the points of the pixel value determination unit 142B and the display unit 34B are changed as the statistical value calculation unit 141B of the thumbnail image generation unit 130B includes a comparison statistical value calculation unit.

[0305] In addition, in this embodiment, it is assumed that the second time range TR2 is a plurality of second time ranges TR2, and the second thumbnail image SG2 is a plurality of second thumbnail images SG2. In addition, the rest of the configuration is the same as that of the image processing device 3 .

[0307] In the thumbnail generation unit 130B, ...

Abstract

The objective of the present invention is to provide an image processing technology which is capable of instantly selecting a desired time range out of the entire duration of a moving image. An image processing device (3) according to the present invention comprises: a moving image acquisition unit (110) which acquires a moving image; a time range setting unit (120) which sets a first time range (TR1) and a second time range (TR2) within the entire duration of the moving image; a thumbnail generation unit (130) which generates a first thumbnail image (SG1) and a second thumbnail image (SG2) which are still images obtained by statistically processing frame images in the first time range (TR1) and the second time range (TR2), respectively; and a display unit (34) which displays the first thumbnail image (SG1) and the second thumbnail image (SG2) such that the images can be visually compared.

Description

technical field [0001] The present invention relates to an image processing technique for taking a dynamic image of a human body or an animal's body. Background technique [0002] At medical sites, various examinations and diagnoses are performed by imaging affected parts included in internal organs, bones, etc. using X-rays or the like. In addition, in recent years, the application of digital technology has made it possible to obtain relatively easily a moving image (an image group composed of a plurality of frame images) that captures the movement of an affected part using X-rays or the like. [0003] Therefore, it is possible to take a moving image of the object area including the area to be diagnosed by using a semiconductor image sensor such as an FPD (flat panel detector), so it is impossible to implement it in conventional still image imaging and diagnosis based on X-ray imaging. Pathological analysis and diagnosis resulting from activity analysis of the diagnosis ta...
