Abstract

A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains an organ model, in which the target organ for treatment is expressed, based on a medical image; identifies a treatment condition which represents a treatment-related condition including at least the treatment position in the organ model; estimates a post-treatment feature quantity based on the organ model and the treatment condition; decides on a display condition regarding the treatment position in the organ model based on the estimated feature quantity; and displays, in a display device, the organ model according to the decided display condition.

First claim

What is claimed is:

1 . A medical image processing apparatus comprising processing circuitry that
obtains an organ model, in which a target organ for treatment is expressed, based on a medical image, identifies a treatment condition which represents a treatment-related condition including at least treatment position in the organ model, estimates a post-treatment feature quantity based on the organ model and the treatment condition, decides on a display condition regarding the treatment position in the organ model based on the estimated feature quantity, and displays, in a display device, the organ model according to the decided display condition.

2 . The medical image processing apparatus according to claim 1 , wherein the processing circuitry
identifies the treatment condition including a plurality of the treatment position, estimates the feature quantity at each of the plurality of treatment positions, and decides on a display condition regarding the treatment positions in the organ model based on the plurality of estimated feature quantities.

3 . The medical image processing apparatus according to claim 1 , wherein, from a user, the processing circuitry receives an input specifying a region in the organ model and identifies the treatment position based on the input.

4 . The medical image processing apparatus according to claim 3 , wherein
the treatment condition includes a device condition related to a treatment device that is involved in treatment of the organ, and the processing circuitry
receives, from a user, an input specifying the device condition,
identifies the device condition based on the input, and
identifies the treatment position based on the input and the identified device condition.

5 . The medical image processing apparatus according to claim 4 , wherein the processing circuitry evaluates ease of retainment of the treatment device and, based on evaluation result, corrects the decided display condition.

6 . The medical image processing apparatus according to claim 4 , wherein the processing circuitry displays, in the display device, the organ model and information indicating the identified device condition.

7 . The medical image processing apparatus according to claim 1 , wherein
the processing circuitry further includes a calculating unit that
estimates a plurality of types of the feature quantity, and
calculates integrated feature quantity by integrating the plurality of estimated types of feature quantity, and
the deciding unit decides on the display condition based on the integrated feature quantity that is calculated.

8 . The medical image processing apparatus according to claim 1 , wherein the display condition includes at least one of conditions related to color, luminosity, color saturation, permeability, thickness of a frame in which the treatment position is expressed, color of the frame, and shape of the frame.

9 . The medical image processing apparatus according to claim 8 , wherein the processing circuitry
estimates a plurality of types of the feature quantity, and for each of the types of feature quantity, decides on the display condition of a different type.

10 . The medical image processing apparatus according to claim 1 , wherein the processing circuitry
receives, from a user, an input about information indicating the treatment position, identifies the treatment position based on the received information indicating the treatment position, estimates, as effect of treatment in case of performing treatment at the treatment position, the post-treatment feature quantity in case of performing treatment at the identified treatment position, decides on the display condition based on extent of the estimated effect of treatment, and displays, in the organ model, information indicating relationship between the treatment position and the effect of treatment.

11 . The medical image processing apparatus according to claim 10 , wherein the processing circuitry
receives input of information indicating a plurality of the treatment position, and decides on the display condition in such a way that the effect of treatment at each of the plurality of treatment positions is distinguishable.

12 . The medical image processing apparatus according to claim 1 , wherein the processing circuitry
obtains the organ model in which mitral valve is expressed, identifies the treatment condition that at least includes
type and size of a mitral valve repairing device used in performing edge-to-edge repair in which a synapsed region is increased by grasping anterior leaflet and posterior leaflet of the mitral valve, and
positions of the anterior leaflet and the posterior leaflet that represent the treatment position and that are grasped using the mitral valve repairing device, and
estimates the feature quantity regarding shape of the mitral valve after the anterior leaflet and the posterior leaflet are grasped using the mitral valve repair device.

13 . A medical image processing method implemented in a medical image processing apparatus, comprising:
obtaining an organ model, in which a target organ for treatment is expressed, based on a medical image; identifying a treatment condition which represents a treatment-related condition including at least treatment position in the organ model; estimating a post-treatment feature quantity based on the organ model and the treatment condition; deciding on a display condition regarding the treatment position in the organ model based on the estimated feature quantity; and displaying, in a display device, the organ model according to the decided display condition.

14 . A non-transitory computer-readable storage medium having a computer program stored therein, wherein the computer program
obtains an organ model, in which a target organ for treatment is expressed, based on a medical image, identifies a treatment condition which represents a treatment-related condition including at least treatment position in the organ model, estimates a post-treatment feature quantity based on the organ model and the treatment condition, decides on a display condition regarding the treatment position in the organ model based on the estimated feature quantity, and displays, in a display device, the organ model according to the decided display condition.
