Home » APOLLO
APOLLO lasers are used for precise and repeatable positioning of radiotherapy patient. After imaging based planning via CT or MRI, the patient is positioned at linear accelerator. The laser lines project the Linac isocenter coordinates onto the patient’s skin, allowing for precise alignment to millimeter accuracy with the CT/ MRI. In addition, the room lasers are fundamental component for quality assurance. They aid in the precise orientation of the phantom, to achieve measurement accuracy.
The APOLLO system has tree (optionally four) lasers for the coronal, sagittal and tranversal body planes. Laser colour, line and/ or cross laser and mounting option can be adapted to individual room situation. The optional fourth laser prevents possible shadowing for the linac gantry.
