no. 2 Embodiment approach

[0132] Next, a second embodiment of the present invention will be described.

[0133] Since the present embodiment is a modified example of the above-mentioned first embodiment, the same parts as those described in the first embodiment are given the same reference numerals and description thereof will be omitted. The present embodiment differs from the first embodiment described above in the calculation method of the fluctuation amount in the fluctuation amount calculation unit.

[0134] The variation calculation unit 103 of the present embodiment is configured based on the luminance of pixels on the image acquired by the image acquisition unit 102 at an arbitrary timing as an arbitrary timing and the respiratory movement achieved in the imaging target area before the arbitrary timing. The difference between the luminances of the pixels on the image obtained at the reference time of the timing of the predetermined extreme position in the image is calculated as the variation am...

[0146] Next, a third embodiment of the present invention will be described.

[0147] Since this embodiment is a modified example of the above-mentioned first embodiment, the same parts as those described in the first embodiment are denoted by the same reference numerals and description thereof will be omitted. The present embodiment differs from the above-mentioned first embodiment in the calculation method of the fluctuation amount in the fluctuation amount calculation unit.

[0148] The imaging region setting unit 101 in the present embodiment is configured to set an imaging target region ROI centering on the pixel region in which the brightness of pixels on an image obtained by imaging the subject M has the largest temporal change.

[0149] In addition, the variation calculation unit 103 in the present embodiment is configured to acquire the second area of ​​pixels having approximately the same luminance distribution as the first area from the second time point which is a p...

no. 4 Embodiment approach

[0192] Next, a fourth embodiment of the present invention will be described.

[0193] Since the present embodiment is a modified example of the above-mentioned first embodiment, the same parts as those described in the first embodiment are given the same reference numerals and description thereof will be omitted. The calculation method of the fluctuation amount in the fluctuation amount calculation unit of this embodiment is different from that of the first embodiment described above.

[0194] The variation calculation unit 103 in this embodiment is configured to extract, from within the imaging target region ROI on the image acquired by the image acquisition unit 102 at an arbitrary timing as an arbitrary timing, a region having substantially the same brightness distribution as the first region. For the second area of ​​pixels, the moving distance from the position of the first area to the position of the second area in the imaging target area ROI is calculated as the variati...

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 difference between 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 the second 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 first time.

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...
