Abstract
In an imaging system including a gantry having a patient bore, and a patient table having a cradle, a method of aligning the cradle with a scan plane in the patient bore is disclosed. The method comprises positioning a laser device at least partially within the patient bore, the laser device producing an alignment laser beam projecting along a center axis of the patient bore normal to the scan plane. The method further comprises aligning the cradle of the patient table such that when the cradle is translated into the scan plane in the patient bore, the alignment laser beam intersects a positioning target on the cradle.
Claims18
For an imaging system including a gantry having a patient bore, and a patient table having a cradle, a method of aligning the cradle with a scan plane in the patient bore, comprising:
- positioning a laser device at least partially within the patient bore, the laser device producing an alignment laser beam projecting along an axis of the patient bore normal to the scan plane;
- and
- aligning the cradle of the patient table such that when the cradle is translated into the scan plane in the patient bore, the alignment laser beam intersects a positioning target on the cradle.
For an imaging system including a gantry having a patient bore, and a patient table having a cradle, a method of aligning the cradle with a scan plane in the patient bore, comprising:
- positioning a laser device at least partially within the patient bore, the laser device producing an alignment laser beam projecting along an axis of the patient bore normal to the scan plane;
- and
- aligning the cradle of the patient table such that when the cradle is translated into the scan plane in the patient bore, the alignment laser beam intersects a positioning target on the cradle,
- wherein the laser device further produces a plurality of coplanar laser beams perpendicular to the alignment laser beam, each coplanar laser beam intersecting an associated positioning point on a septum.
For an imaging system including a gantry having a patient bore, and a patient table having a cradle, a method of aligning the cradle with a scan plane in the patient bore, comprising:
- positioning a laser device at least partially within the patient bore, the laser device producing an alignment laser beam projecting along an axis of the patient bore normal to the scan plane;
- advancing the cradle into the patient bore;
- and
- repeatedly determining that the alignment laser beam intersects a positioning target on the cradle when the cradle is being advanced into the patient bore.
For an imaging system including a gantry having a patient bore, and a patient table having a cradle, a method of aligning the cradle with a scan plane in the patient bore, comprising:
- positioning a laser device at least partially within the patient bore, the laser device producing an alignment laser beam projecting along an axis of the patient bore normal to the scan plane;
- advancing the cradle into the patient bore;
- and
- repeatedly determining that the alignment laser beam intersects a positioning target on the cradle when the cradle is being advanced into the patient bore,
- wherein the laser device produces a plurality of coplanar laser beams perpendicular to the alignment laser beam, each coplanar laser beam intersecting an associated positioning point on a septum.
An imaging system comprising:
- a gantry including a patient bore;
- a patient table including a cradle;
- and
- a laser device positioned at least partially within the patient bore and configured to produce an alignment laser beam projecting along an axis of the patient bore normal to a scan plane,
- wherein the alignment laser beam is configured to intersect a positioning target on the cradle such that the cradle is normal to the scan plane when the cradle is translated into the patient bore.
An imaging system comprising;
- a gantry including a patient bore;
- a patient table including a cradle;
- and
- a laser device positioned at least partially within the patient bore and configured to produce an alignment laser beam projecting alone an axis of the patient bore normal to a scan plane,
- wherein the alignment laser beam is configured to intersect a positioning target on the cradle such that the cradle is normal to the scan plane when the cradle is translated into the patient bore, and
- the laser device is configured to produce a plurality of coplanar laser beams perpendicular to the alignment laser beam, each coplanar laser beam configured to intersect an associated positioning point on a septum.
