no. 1 approach

[0051] (2.1) Image capture system

[0052] The first embodiment relates to an image capture system.

[0053] Figure 5 The block diagram of : shows the image capturing system of the first embodiment.

[0054] Figure 5 The illustrated image capture system 1000 includes a capture device 1010 and an image analysis device 1011 . The camera 1010 generates medical dynamic images. The image analysis device 1011 analyzes the medical video and derives an index indicating lung function. According to the image analysis device 1011 , lung function can be tested with good reproducibility without imposing a large burden on the person being tested.

[0055] (2.2) Shooting device

[0056] The imaging device 1010 generates medical dynamic images through X-ray imaging. The imaging device 1010 uses an X-ray tube to generate X-rays, passes the generated X-rays through the human body, and detects the X-rays that have passed through the human body with a planar X-ray detector (FPD). In this ...

no. 2 approach

[0129] The second embodiment relates to an image analysis unit that replaces the image analysis unit of the first embodiment. The image analysis unit of the second embodiment differs from the image analysis unit of the first embodiment mainly in that the influence of the heartbeat is eliminated.

[0130] Figure 11 The block diagram of FIG. 2 shows the image analysis unit of the second embodiment. Figure 12 The schematic diagram of shows the content of the image analysis of the second embodiment.

[0131] Figure 11 The illustrated image analysis unit 2000 includes a low-pass filter unit 2010 , an extraction unit 2011 , and a derivation unit 2012 .

[0132] The low-pass filter unit 2010 applies a time-domain low-pass filter to two or more frame images Img(1), . . . , Img(m). In this way, two or more frame images Img'(1), . The blocking frequency of the low-pass filter is the same as that of the first embodiment, which is the middle of the respiratory frequency and the he...

no. 3 approach

[0136]The third embodiment relates to an image analysis unit that replaces the image analysis unit of the first embodiment. The image analysis unit of the third embodiment differs from the image analysis unit of the first embodiment mainly in that the influence of the heartbeat is eliminated.

[0137] Figure 13 The block diagram of the figure shows the image analysis unit of the third embodiment. Figure 14 The schematic diagram of shows the content of the image analysis of the 3rd embodiment.

[0138] Figure 13 The illustrated image analysis unit 3000 includes an extraction unit 3010 , a low-pass filter unit 3011 , and a derivation unit 3012 .

[0139] The extraction unit 3010 extracts a heart region Rgn(i) from each of two or more frame images Img(1), . . . , Img(m). Thereby, two or more heart regions Rgn(1), . . . , Rgn(m) are extracted.

[0140] The low-pass filter unit 3011 applies a time-domain low-pass filter to two or more heart regions Rgn(1), . . . , Rgn(m). ...

Abstract

An image analysis device includes: an acquiring unit configured to acquire a moving image showing a variation of a respiratory status, the moving image being formed with frame images including an image of a heart; an image analyzing unit configured to generate a first index indicating a cardiac status with respect to each of the frame images; and an index analyzing unit configured to derive a second index indicating lung function from a change caused in the first indexes by the respiratory status.

Description

technical field [0001] The present invention relates to an image analysis device, an image capture system, and an image analysis program for deriving an index indicating lung function Background technique [0002] Spirometry is sometimes performed when diagnosing lung diseases such as chronic obstructive pulmonary disease (COPD). In spirometry, the air exchange rate of the person being examined is determined. From the measured ventilation volume, indicators such as vital capacity and 1-second rate are sometimes derived, and a graph called a spirometry is sometimes created. [0003] The invention described in Patent Document 1 derives blood flow information. In the invention described in Patent Document 1, the site of the heart wall is automatically detected from a chest X-ray dynamic image, and the amount of change in the site of the heart wall is used as the amount of movement of the heart wall. Based on the movement of the heart wall, the phase of the heartbeat is infer...
