[0045] [Structure of Chest Diagnosis Support System 100]

[0046] figure 1 The overall structure of the chest diagnosis support system 100 in this embodiment is shown.

[0047] Such as figure 1 As shown, the chest diagnosis support system 100 is configured such that the imaging device 1 and the imaging console 2 are connected via a communication cable or the like, and the imaging console 2 and the diagnostic console 3 are connected via a communication network such as a LAN (Local Area Network, local area network). NT connection. Each device constituting the chest diagnostic assistance system 100 complies with the DICOM (Digital Image and Communications in Medicine, medical digital imaging and communication) standard, and the communication between each device is based on DICOM.

[0048] [Structure of Imaging Device 1]

[0049] The imaging device 1 is, for example, a device that captures periodic (circular) movement of the chest such as expansion and contraction of the lun...

no. 2 approach

[0126] Next, a second embodiment will be described.

[0127] In the second embodiment, the difference from the first embodiment is that the template of the maximum airflow velocity distribution (normal airflow velocity distribution template) and the content of image analysis processing executed in the control unit 31 of the diagnostic console 3 are different from those in the first embodiment. In addition, since the overall structure of the chest diagnosis support system 100, the structure of each device, and the operations of the imaging device 1 and the imaging console 2 are the same as those described in the first embodiment, the descriptions in the first embodiment are cited. illustrate.

[0128] Hereinafter, image analysis processing (referred to as image analysis processing B) in the second embodiment will be described.

[0129] Figure 9 A flowchart of the image analysis processing B in the second embodiment is shown in . The image analysis processing B is executed ...

Abstract

According to one implementation, a thoracic diagnosis assistance information generation method includes the following. A dynamic state of a chest portion is captured to generate frame images. Air velocity is calculated by dividing a lung field region extracted from one frame region into small regions, corresponding the small regions among the frame images, and calculating a feature amount showing air velocity. Air velocity distribution is calculated by dividing the lung field region into block regions in a trunk axis direction, calculating a feature amount showing air velocity of each block region based on a feature amount showing the air velocity of the small regions in the divided block regions, and calculating a feature amount showing air velocity distribution of the lung field region based on the calculated feature amount showing the air velocity of each block region.

Description

technical field [0001] The invention relates to a method for generating auxiliary information for chest diagnosis, an auxiliary system for chest diagnosis and a dynamic image processing device. Background technique [0002] Compared with the static image capture and diagnosis of the chest based on radiation using films / screens and luminous phosphor panels in the past, attempts are being made to capture dynamic images of the chest using semiconductor image sensors such as FPDs (flat panel detectors) , and applied to the diagnosis. [0003] Specifically, using the rapidity of the responsiveness of the semiconductor image sensor to read / erase image data, pulsed radiation is continuously irradiated from the radiation source according to the timing of semiconductor image sensor read / erase, multiple times within one second. Shoot, to shoot the dynamics of the chest. By sequentially displaying a series of a plurality of images obtained by imaging, a physician can observe a series...
