Method, apparatus and medical imaging system for tracking motion of organ

A device configured to track motion of an organ, comprising:

• an interface unit configured to receive organ shape data that comprises a shape of an organ of an examinee at a moment of motion of the examinee;
• a storage device configured to store first to Nth interpolation curves that represent spatiotemporal motion of respective organs of other examinees, the organs of the other examinees being the same type as the organ of the examinee;
• and
• a motion tracking unit configured to estimate an interpolation curve that represents a spatiotemporal motion of the organ of the examinee based on the first to Nth interpolation curves and the organ shape data.

A medical imaging device comprising:

• an image acquisition device configured to acquire an image of a shape of an organ of an examinee at a moment of motion of the examinee;
• an organ tracking device configured to
• store first to Nth interpolation curves that represent spatiotemporal motion of respective organs of other examinees, the organs of the other examinees being the same type as the organ of the examinee,
• estimate an interpolation curve that represents a spatiotemporal motion of the organ of the examinee based on the first to Nth interpolation curves and the image, and
• obtain organ deformation data that comprise a three-dimensional (3D) shape of the organ of the examinee that deforms over time based on the interpolation curve;
• and
• an image display device configured to display the 3D shape of the organ based on the organ deformation data.
