Abstract

A medical image processing apparatus includes a data acquirer that scans an object with a fiducial marker attached thereto to acquire volume data, and a data processor that estimates a plane of interest, based on a position of the fiducial marker and a position of a landmark in the volume data.

First claim

What is claimed is:

1. A medical image processing method comprising:
scanning an object which has a first attachable marker attached to a surface of the object and a landmark disposed within the object, to acquire first volume data in a first period;
estimating a first plane of interest (POI), based on a position of the first attachable marker and a position of the landmark in the first volume data;
acquiring a first image of interest (IOI) which is an image of the first POI;
scanning the object, with a second attachable marker attached to a same position as that of the first attachable marker in a scan in the first period, to acquire second volume data in a second period;
estimating a second POI which is a same POI as the first POI, based on a position of the second attachable marker, a position of the landmark in the second volume data, and a positional relationship between the first attachable marker and the first POI; and
acquiring a second IOI which is an image of the second POI.

2. A non-transitory computer-readable storage medium storing a computer program which, when executed by a computer, causes the computer to execute the medical image processing method of claim 1 .

3. The medical image processing method of claim 1 , further comprising:
acquiring information about a difference between the first IOI and the second IOI.

4. The medical image processing method of claim 3 , further comprising:
displaying the first IOI and the second IOI together on a display.

5. The medical image processing method of claim 1 , further comprising storing the first IOI.

6. The medical image processing method of claim 1 , wherein the medical image processing method is performed by a magnetic resonance imaging (MRI) apparatus.

7. A medical image processing apparatus comprising:
a processor configured to obtain first volume data in a first period acquired by scanning an object, which has a first attachable marker attached to a surface of the object and a landmark disposed within the object,
to estimate a first plane of interest (POI), based on a position of the first attachable marker and a position of the landmark in the first volume data, and to acquire a first image of interest (IOI) which is an image of the first POI; and
a storage unit which is coupled to the processor and stores the first IOI,
wherein, in a second time period, the processor obtains second volume data acquired by scanning the object with a second attachable marker attached to a same position as that of the first attachable marker in a scan in the first period, estimates a second POI which is a same POI as the first POI, based on a position of the second attachable marker, a position of the landmark in the second volume data, and a positional relationship between the first attachable marker and the first POI, and acquires a second IOI which is an image of the second POI.

8. The medical image processing apparatus of claim 7 , wherein the processor is configured to acquire information about a difference between the second IOI and the first IOI which has been stored in the storage unit.

9. The medical image processing apparatus of claim 6 , further comprising:
a display configured to display together the second IOI and the first IOI,
wherein the first IOI is retrieved from the storage unit.

10. The medical image processing apparatus of claim 7 , wherein the medical image processing apparatus is a magnetic resonance imaging (MRI) apparatus.

11. The medical image processing apparatus of claim 7 , wherein the first attachable marker and the second attachable marker are attached to at least one among a nose, an ear, and a philtrum of the object.

12. A medical image processing apparatus comprising:
a communication interface which is coupled to a processor and receives volume data about an object having an attachable marker attached to a surface of the object and a landmark disposed within the object; and
a data processor configured to detect, in the volume data, a position of the attachable marker, to detect a mid-sagittal plane (MSP), to detect a position of the landmark from the detected MSP, and to estimate a plane of interest (POI) in the object, based on the detected position of the attachable marker and the detected position of the landmark.

13. The medical image processing apparatus of claim 12 , wherein the medical image processing apparatus is a magnetic resonance imaging (MRI) apparatus.

14. The medical imaging processing apparatus of claim 12 , wherein the attachable marker is attached to at least one among a nose, an ear, and a philtrum of the object.

15. A medical image processing apparatus comprising:
a processor configured to obtain first volume data in a first period acquired by scanning an object having a first attachable marker attached to a surface of the object and a landmark disposed within the object, to obtain second volume data in a second time period acquired by scanning the object having a second attachable marker attached to a same position as that of the first attachable marker in a scan in the first period,
to estimate a first plane of interest (POI), based on a position of the first attachable marker and a position of the landmark in the first volume data, and to perform automatic view planning, based on a position of the second attachable marker, a position of the landmark in the second volume data, and a positional relationship between the first attachable marker and the first POI.

16. The medical image processing apparatus of claim 15 , wherein the medical image processing apparatus is a magnetic resonance imaging (MRI) apparatus.

17. The medical image processing apparatus of claim 15 , wherein the first attachable marker and the second attachable marker are attached to at least one among a nose, an ear, and a philtrum of the object.

18. A medical imaging system comprising:
a medical apparatus comprising a medical scanner which scans an object and acquires a scan signal; and
a medical image processing apparatus which is connected to the medical apparatus,
wherein the medical image processing apparatus comprises:
a processor which obtains first volume data in a first period acquired by scanning the object, which has a first attachable marker attached to a surface of the object and a landmark disposed within the object; and
a data processor configured to estimate a first plane of interest (POI), based on a position of the first attachable marker and a position of the landmark in the first volume data and acquire a first image of interest (IOI) which is an image of the first POI,
wherein, in a second time period, the processor obtains second volume data acquired by scanning the object with a second attachable marker attached to a same position as that of the first attachable marker in a scan in the first period, and the data processor estimates a second POI which is a same POI as the first POI, based on a position of the second attachable marker, a position of the landmark in the second volume data, and a positional relationship between the first attachable marker and the first POI, and acquires a second IOI which is an image of the second POI.

19. The medical imaging system of claim 18 , wherein the medical scanner is configured to perform a scout scan of the object to acquire the scan signal.

20. The medical imaging system of claim 19 , wherein the medical scanner is configured to rescan the object to acquire a rescan signal, to acquire a third IOI which is an image of the second POI estimated by the medical image
