Abstract

An apparatus for simulating an image-guided procedure. The system comprises an input for receiving a three-dimensional (3D) medical image depicting an organ of a patient, a model generation unit for generating a 3D anatomical model of the organ according to the 3D medical image, and a simulating unit for simulating a planned image-guided procedure on the patient, according to the 3D anatomical model.

Claims

1. An apparatus for simulating an image-guided procedure, comprising:

an input for receiving a three-dimensional (3D) medical image depicting an organ of a patient;

a model generation unit configured for generating a 3D anatomical model of said organ according to said 3D medical image; and

a simulating unit configured for simulating an image-guided procedure planned for said patient according to said 3D anatomical model.

2. The apparatus of claim 1, further comprising a segmentation unit operatively connected to said model generation unit, said segmentation unit being configured for segmenting said organ in said 3D medical image to a plurality of areas, said segmented organ image being used for generating said 3D anatomical model.

3. The apparatus of claim 1, wherein said 3D anatomical model is a model of a tract.

4. The apparatus of claim 3, wherein said tract is a member of the following group:

a vascular tract, a urinary tract, a gastrointestinal tract, and a fistula tract.

5. The apparatus of claim 1, wherein said 3D medical image is a member of the following group:

computerized tomography (CT) scan images, magnetic resonance imager (MRI) scan images, ultrasound scan images, and positron emission tomography (PET)-CT scan images.

6. The apparatus of claim 1, wherein said planned image-guided procedure is an angioplasty procedure.

7. The apparatus of claim 1, further comprises a user interface operatively connected to said model generation unit, said user interface allows a user to instruct said model generation unit during the generation of said 3D anatomical model.

8. The apparatus of claim 1, wherein said simulated planned image-guided procedure is used as a study case during a learning process.

9. The apparatus of claim 1, wherein said simulated planned image-guided procedure is used to demonstrate a respective image-guided procedure to said patient.

10. The apparatus of claim 1, wherein said simulated planned image-guided procedure is used to document preparation to an operation.

11. The apparatus of claim 1, wherein said input is configured for receiving a four dimensional (4D) medical image depicting said organ during a certain period, said model generation unit configured for generating a 4D organ model of said organ according to said 4D medical image, said simulating unit configured for simulating an image-guided procedure planned for said patient according to said 4D organ model.

12. The apparatus of claim 1, wherein said organ is a member of a group comprising:

an anatomical region, a human body system, an area of an organ, a number of areas of an organ, a section of an organ, and a section of a human body system.

13. A method for performing a simulated image-guided procedure, said method comprising:

a) obtaining a three-dimensional (3D) medical image depicting an organ of a patient;

b) producing a 3D anatomical model of said organ according to said 3D medical image; and
