Abstract
A method including obtaining reference image data-sets of a tissue related to respective reference patient tilt angles, wherein each reference image data-set is associated with a respective tilt angle, which is a combination of axial and transverse gravitational force components applied to the tissue, using the reference image data-sets to derive a formula relating an image data-set of said tissue to a given combination of axial and transverse gravitational force components, and using the formula to simulate an image data-set of a desired patient tilt angle.
Claims11
A method comprising:
- obtaining reference image data-sets of a tissue related to respective reference patient tilt angles, wherein each reference image data-set is associated with a respective tilt angle, which is a combination of axial and transverse gravitational force components applied to the tissue;
- using the reference image data-sets to derive a formula relating an image data-set of said tissue to a given combination of axial and transverse gravitational force components;
- and
- using the formula to simulate an image data-set of a desired patient tilt angle.
A method for simulating desired tissue data-set related to a desired patient tilt angle comprising:
- positioning a patient in a reference patient tilt angle;
- attaching a rigid container to a tissue in a known position relative to the patient;
- applying a force on the tissue such that the tissue adopts the shape of the container;
- obtaining a reference image data-set;
- and
- applying a formula to the reference image data-set to obtain the desired tissue data-set related to a desired patient tilt angle.
A couch for scanning a tilted patient comprising:
- a tabletop rotatable about a horizontal axis;
- a tilting device for tilting said tabletop to a desired patient tilt angle about the horizontal axis;
- and
- an actuator for moving said tabletop longitudinally perpendicular to the horizontal axis.
Apparatus comprising:
- a container for partially enclosing therein a first body portion, said container operable to keep said first body portion in a given position relative to a second body portion irrespective of tilt-angle, wherein said first body portion is forced to comply with an internal shape of said container, and wherein said container is constructed to enable imaging of said first body portion.
