Abstract
A method for centering a left atrium and pulmonary veins at an isocenter of an imaging device is provided. The method includes positioning an injection catheter at a bifurcation of a pulmonary artery; obtaining an anterior or posterior flouroscopic image of area including and/or surrounding the left atrium and pulmonary veins; and moving the imaging device, patient support, or the combination thereof, such that the injection catheter and a spine of a patient are displayed in the fluoroscopic image.
Claims20
A method for generating a three-dimensional (3D) representation of a left atrium and pulmonary veins, the method comprising:
- positioning the left atrium at an isocenter of an imaging device as a function of an injection catheter and a spine of a patient;
- obtaining a 3D-data set of the left atrium and pulmonary veins using the imaging device with the left atrium positioned at the isocenter;
- and
- generating a 3D representation of the left atrium and pulmonary veins using the 3D-data set.
A system for generating a three-dimensional (3D) representation of the left atrium and pulmonary veins, the system comprising:
- an imaging device operable to obtain an image of the left atrium and the pulmonary veins as a function of an injection catheter and a spine of a patient;
- and
- an image processing device having a monitor that is operable to display the image of the left atrium and the pulmonary veins,
- wherein the imaging device is operable to be positioned such that the monitor displays the spine of a patient and the injection catheter at a same time.
The system as claimed in 16, wherein the image processing device is operable to segment the left atrium and the pulmonary veins from the 3D representation.
An imaging system comprising:
- an image processing device operable to position a left atrium and pulmonary veins as a function of an injection catheter and a spine of a patient and further operable to instruct an imaging device to obtain an anterior or posterior fluoroscopic image of an area including, surrounding, or including and surrounding the left atrium and the pulmonary veins,
- wherein the image processing device is operable to move the imaging device, a patient support, or a combination thereof, such that the injection catheter and the spine of the patient are displayed in the fluoroscopic image.
