Medical image processing apparatus, medical image processing method, and program
Provided are a medical image processing apparatus and a medical image processing method that effectively display an observation state indication related to the comprehensiveness of observation while suppressing a decrease in the visibility of an endoscopic image. The medical image processing apparatus is a medical image processing apparatus including a processor and a memory. The processor is configured to acquire a plurality of medical images in a time-series manner, make a determination of an observation state in units of a small area of a photographic subject on the basis of the medical images, cause the memory to store a result of the determination, and upon an observation state of the photographic subject being changed, cause a monitor to display an observation state indication of the photographic subject, the observation state indication being based on the result of the determination stored in the memory.
1. A medical image processing apparatus comprising one or more processors and one or more memories,
the one or more processors being configured to:
acquire a plurality of medical images in a time-series manner;
make a determination of an observation state of each of a plurality of predetermined areas in an organ of a photographic subject positioned differently from each other, using the plurality of medical images, to determine that the observation state is observation-completed in a case where observation is completed and determine that the observation state is observation-uncompleted in a case where observation is uncompleted;
display, on a monitor, a notification that the observation state of each of the plurality of predetermined areas of the photographic subject is observation-uncompleted or observation-completed, on the basis of a result of the determination;
cause the one or more memories to store the result of the determination; and
update, in a case where the observation state of any one of the plurality of areas of the photographic subject changes from observation-uncompleted to observation-completed, a display on the monitor to inform that the observation state of the one area is the observation-completed.
2. The medical image processing apparatus according to claim 1 , wherein the processor is configured to cause an observation state indication displayed on the monitor to be hidden after a predetermined time elapses.
3. The medical image processing apparatus according to claim 1 , further comprising
a user operation acceptance unit, wherein
the processor is configured to cause an observation state indication to be displayed or hidden on the basis of an instruction from the user operation acceptance unit.
4. The medical image processing apparatus according to claim 1 , wherein the processor is configured to, in a case of determining an observation state in units of a small area of the photographic subject on the basis of the medical images, determine that observation is completed in a case where observation of the small area has been completed, and determine that observation is uncompleted in a case where observation of the small area has not been completed.
5. The medical image processing apparatus according to claim 1 , wherein the processor is configured to cause the monitor to display an observation state indication by using text information.
6. The medical image processing apparatus according to claim 5 , wherein the processor is configured to provide the text information with information regarding completion or incompletion of observation of units of a small area of the photographic subject, and cause the monitor to display, as the observation state indication, the text information provided with the information.
7. The medical image processing apparatus according to claim 1 , wherein the processor is configured to cause an observation state indication to be displayed by using a photographic subject model schematically representing the photographic subject.
8. The medical image processing apparatus according to claim 7 , wherein the processor is configured to provide the photographic subject model with information regarding completion or incompletion of observation of units of a small area of the photographic subject, and cause the monitor to display, as the observation state indication, the photographic subject model provided with the information.
9. The medical image processing apparatus according to claim 1 , wherein the processor is configured to cause the monitor to display, as an observation state indication, an indication indicating only completion of observation of units of a small area of the photographic subject or an indication indicating only incompletion of observation of the unit of the small area of the photographic subject.
10. The medical image processing apparatus according to claim 1 , wherein the processor is configured to cause the monitor to display the medical images such that an observation state indication is superimposed on the medical images.
11. The medical image processing apparatus according to claim 1 , wherein the processor is configured to cause a monitor having a first display region and a second display region smaller than the first display region to display an observation state indication in the first display region and the second display region in a manner different between the first display region and the second display region.
12. The medical image processing apparatus according to claim 11 , wherein the processor is configured to cause the observation state indication to be constantly displayed in the second display region.
13. The medical image processing apparatus according to claim 11 , wherein the processor is configured to cause a monitor having the first display region and a third display region different from the second display region to display the medical images in the third display region.
14. The medical image processing apparatus according to claim 1 , wherein the one or more processors are configured to make the determination of the observations state with a trained model which are learned to recognize each of the plurality of the areas.
15. A medical image processing method for a medical image processing apparatus comprising one or more processors and one or more memories,
the one or more processors being configured to execute:
a medical image acquisition step of acquiring a plurality of medical images in a time-series manner;
an observation state determination step of making a determination of an observation state of each of a plurality of predetermined areas in an organ of a photographic subject positioned differently from each other, using the plurality of medical images, to determine that the observation state is observation-completed in a case where observation is completed and determine that the observation state is observation-uncompleted in a case where observation is uncompleted;
a display step of displaying, on a monitor, a notification that the observation state of each of the plurality of predetermined areas of the photographic subject is observation-uncompleted or observation-completed, on the basis of a result of the determination;
a storage step of causing the one or more memories to store the result of the determination; and
an update step of updating, in a case where the observation state of any one of the plurality of areas of the photographic subject changes from observation-uncompleted to observation-completed, a display on the monitor to inform that the observation state of the one area is the observation-completed.
16. A non-transitory computer-readable tangible recording medium storing a program which causes, when read by a computer, the computer to execute the medical image processing method according to claim 15 .
