APOLLO room lasers are used for precise and repeatable positioning of radiotherapy patients. After imaging-based planning via CT or MRI, the patient is positioned at the linear accelerator. The finest 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 a fundamental component of quality assurance. They aid in the precise orientation of the phantom, to achieve measurement accuracy. The APOLLO system has three (optionally four) lasers for the coronal, sagittal and transversal body planes. You can choose the laser color, line and/or cross laser, and mounting option, all adapted to your individual room situation. An optional fourth laser prevents possible shadowing from the LINAC gantry.
