Abstract
In a method and system for displaying a medical image, a user defines three points in an anatomy of interest at different locations. A plane is then automatically generated from the three points.
Claims22
A method for generating a planar medical image of a portion of the human anatomy, comprising the steps of:
- providing a computer having a 3-D stored image of said portion of the human anatomy;
- creating a first image slice of the 3-D stored image at a first image orientation and depth and defining a first point in the first slice;
- creating a second image slice of the 3-D stored image at a second image orientation and depth and defining a second point in the second slice;
- creating a third image slice of the 3-D stored image at a third image orientation and depth and defining a third point in the third slice;
- calculating a plane in the 3-D stored image described by the three points;
- and
- creating a fourth image slice of said 3-D stored image as said planar medical image from said calculated plane.
A method for generating a planar medical image using multi-planar reformatting of a portion of the human anatomy using multi-planar reformatting, comprising the steps of:
- providing a computer having a 3-D stored image of said portion of the human anatomy;
- displaying a first image slice of the 3-D stored image at a first image orientation and depth, or creating and displaying a first multi-planar reformatted image slice of the 3-D stored image at a first image orientation and depth, and defining a first point in the first slice;
- for said same given direction, displaying a second image slice of the 3-D stored image at a second image depth, or creating and displaying a second multi-planar reformatted image slice of the 3-D stored image at a second image orientation and depth, and defining a second point in the second slice;
- for said same given direction, displaying a third image slice of the 3-D stored image at a third image depth, or creating and displaying a third multi-planar reformatted image slice of the 3-D stored image at a third image orientation and depth, and defining a third point in the third slice;
- calculating a plane in the 3-D stored image described by the three points;
- and
- creating and displaying a fourth image slice of said 3-D stored image as said planar medical image from said calculated plane.
A system for generating a planar medical image of a portion of the human anatomy, comprising:
- a computer having a display and a storage which can store a 3-D stored image of said portion of the human anatomy;
- and
- a software program in the computer which
- creates a first image slice of the 3-D stored image at a first image orientation and depth and permits a user to define a first point in the first slice when it is shown on the display,
- creates a second image slice of the 3-D stored image at a second image orientation and depth and permits the user to define a second point in the second slice when it is shown on the display,
- creates a third image slice of the 3-D stored image at a third image orientation and depth and permits the user to define a third point in the third slice when it is shown on the display,
- calculates a plane in the 3-D stored image described by the three points, and
- creates a fourth image slice of said 3-D stored image from said calculated plane which is then shown on the display.
A computer program product employed in a computer having a 3-D stored image of a portion of the human anatomy for use in generating a planar medical image of said portion of the human anatomy, said computer program product performing the steps of:
- creating a first image slice of the 3-D stored image at a first image orientation and depth and defining a first point in the first slice;
- creating a second image slice of the 3-D stored image at a second image orientation and depth and defining a second point in the second slice;
- creating a third image slice of the 3-D stored image at a third image orientation and depth and defining a third point in the third slice;
- calculating a plane in the 3-D stored image described by the three points;
- and
- creating a fourth image slice of said 3-D stored image as said planar medical image from said calculated plane.
