Respiration monitoring device, respiration monitoring system, medical treatment system, respiration monitoring method, and respiration monitoring program

Abstract

The invention provides a respiration monitoring device, a respiration monitoring system, a medical treating system, a respiration monitoring method, and a respiration monitoring program. The respiration monitoring device comprises an image acquiring section for so acquiring an image that an imaging object region including a body portion of a subject reciprocally moving as the subject respires is inclined at a predetermined angle to the direction in which the body portion reciprocally moves at each predetermined timing, a variation computing section for computing the variation of the position of the imaging object region from a first time which is a given timing to a second time which is a timing coming after a predetermined number of timings from the first time according to the differencebetween the luminance of the pixels of the image acquired at the first time and that at the second time, and a position judging section for judging, as the position of the imaging object region at thesecond time, the position determined by adding the variation of the position of the imaging object region between the first and second times to the position of the imaging object region at the firsttime.

Description

technical field [0001] The present invention relates to respiratory monitoring processing for grasping the respiratory state of a subject. Background technique [0002] Conventionally, when performing imaging such as a CT scan, a technique called a respiratory synchronization scan is used. The so-called breath-synchronized scanning is to scan respiratory moving organs (such as lungs, liver, spleen, etc.) that move along with breathing in a certain phase of the breathing cycle that repeats exhalation and inhalation, thereby A technology that enables imaging at a certain phase. [0003] Therefore, it is possible to obtain an image in which motion artifacts are suppressed even for body parts that are easily affected by motion artifacts caused by respiration and are difficult to obtain clear images. [0004] In order to perform the breath-synchronized scanning as described above, it is necessary to grasp the amount of change in the position of the body surface due to the recip...

Problems solved by technology

[0006] However, in the above-mentioned prior art, in the structure that detects the displacement of the body surface accompanying breathing with the device directly mounted on the body, there is discomfort caused by the installation, and the device enters the shooting range and causes hinder such problems
