no. 1 Embodiment approach

[0025] figure 1 It is a diagram showing a configuration example of a medical data processing system and a medical data processing device according to the first embodiment.

[0026] Such as figure 1 As shown, the medical data processing system 100 of this embodiment includes an X-ray CT (Computed Tomography) device 110 , a medical image storage device 120 , various departmental systems 130 , a medical information display device 140 and a medical data processing device 150 . Here, each device and system can be communicatively connected via the network 160 .

[0027] The X-ray CT apparatus 110 generates a CT image in which a target organ of a subject is drawn. Specifically, the X-ray CT apparatus 110 moves the X-ray tube and the X-ray detector on a circular orbit around the subject to collect projection data representing the distribution of X-rays transmitted through the subject. Examples of the target organ include living body organs such as mitral valve, heart, and lung. In...

no. 2 Embodiment approach

[0120] In the first embodiment described above, the time t is estimated by the second acquisition function 155c in step S6 using the shape-related parameters determined in step S5. a 1. Case 51 of the mitral valve shape after treatment is described. However, the second acquisition function 155c may estimate the time t by using parameters related to motion instead of parameters related to shape. a 1 The shape of the mitral flap after treatment. Therefore, such an embodiment will be described as a second embodiment. In the description of the second embodiment, points different from the above-mentioned first embodiment will be mainly described, and the description of the same configuration as the above-mentioned first embodiment may be omitted.

[0121] In the second embodiment, the second acquisition function 155c applies, to each calculation grid set in the region 21 of the mitral lobe, a preset information based on the size, weight, tension, etc. A mathematical model or a p...

no. 3 Embodiment approach

[0123] In addition, in step S6, the second acquisition function 155c may estimate the time t using both the shape-related parameters and the motion-related parameters determined in step S5. a 1 The shape of the mitral flap after treatment 51 . Therefore, such an embodiment will be described as a third embodiment. In the description of the third embodiment, points different from the above-mentioned first embodiment will be mainly described, and the description of the same configuration as the above-mentioned first embodiment may be omitted.

[0124] In the third embodiment, the second acquisition function 155c applies, to each calculation grid set in the region 21 of the mitral lobe, a preset relationship based on the known size, weight, tension, etc. A mathematical model or a physical model set for the parameters of the clamper, the parameters about the shape and the parameters about the movement determined in step S5. Then, the second acquisition function 155c estimates the...

Abstract

The invention relates to a medical data processing apparatus, a medical data processing method, and a non-transitory computer-readable recording medium. The state of a subject at a timing such as after treatment is estimated more appropriately from information relating to the state of the subject at a timing such as before treatment. A medical data processing device according to an embodiment includes a first acquisition unit, a calculation unit, and an estimation unit. The first acquisition unit acquires estimated data relating to a state of a biological organ at a first timing, and measured data indicating the state of the biological organ at the first timing. The calculation unit calculates a parameter based on the estimated data and the measured data. The estimation unit estimates the state of the organism organ at a predetermined time phase at a second timing different from the first timing on the basis of the parameter and the estimation data at the predetermined time phase.

Description

[0001] References for related applications [0002] This application claims priority based on Japanese Patent Application No. 2020-183315 filed on October 30, 2020, and the entire content of the Japanese Patent Application is cited in this application. technical field [0003] The embodiments disclosed in this specification and the accompanying drawings relate to a medical data processing device, a medical data processing method, and a non-transitory computer-readable recording medium. Background technique [0004] When planning a treatment plan for a subject (patient) with a heart disease, the doctor uses the state of the subject obtained before treatment and the shape or fluid information of the heart to be treated, and decides the treatment based on the doctor's knowledge and experience plan. Ideally, a doctor should plan an optimal treatment plan for the state of the subject after treatment. For this reason, a technique for estimating the state of the subject after tre...
