Ancillary Equipment |
IBA has all the ancillary equipment necessary to complete your PT facility, many of which are manufactured to IBA specifications and packaged together with the core technological components. IBA also combines additional components sourced from other oncology and diagnostic equipment providers for inclusion in the overall PT system purchase, should this be our customer’s requirement.
IBA works together with leading medical equipment manufacturers to ensure complete integration and compatibility between the PT system and ancillary components and systems.
PPS |
The Patient Positioning System: it supports and positions the patient with sub-millimeter accuracy to permit the beam to be delivered with great precision to any point in the patient from any angle. The patient positioner has six degrees of freedom (three linear axes to map out the treatable volume, one rotary axis to position the patient with respect to the angle of the nozzle, and couch pitch and roll to accomplish fine scale adjustment).
Orthogonal Imaging |
The Patient Position Verification System: it consists in two digital X-ray receptor (amorphous silicon flat panels) motorized with automatic motion control for in/out positioning, coupled to x-ray tubes, producing Digital Radiography (DR) during the alignment phase that are further compared to the Digital Reconstructed Radiography (DRR), so as to issue a correction vector to the patient positioner. Two x-ray tubes are furnished per treatment room.
One x-ray tube is located in the nozzle, pointing towards the isocenter (Beam's Eye view); the second tube is located 90° CCW pointing towards the isocenter. A laser set and light field are also provided to give to the therapist visual confirmation of the patient set-up. The laser beam system is composed of line lasers and cross-line lasers.
Respiratory gating |
Many radiation oncology protocols for highly conformal treatment of tumors located near or within the thorax, abdomen, and pelvis now include a form of respiration gating. Motion of the tumor and surrounding anatomy due to respiration can affect the accuracy of the treatment.
In order to compensate for motion or eliminate its effect altogether, the respiration gating system defines beam-on/off periods that are synchronized with the patient's breathing cycle.
This technique permits the therapist to direct the dose to the tumor more accurately, and may result in less dose "spilling" into surrounding healthy tissues.
IBA will integrate a respiration gating system into the IBA Particle Therapy system to enable compensation for respiratory motion, for our customers who select this option.
3 techniques are currently available:
- Respiratory blocking
The patient breathes through an air mask and the air flow is stopped when the lung is filled with a given volume. The beam is then enabled until the patient starts breathing again. The patient has to learn how to hold his breath before treatment.
- Respiratory gating by air flow monitoring
The patient is breathing freely in an air mask and the air volume in the lung is monitored. When the volume in the lung is below or above a given volume, the beam is disabled.
o
- Respiratory gating by chest motion monitoring
The patient is breathing freely and one or a set of "targets" are positioned on the patient chest. Those "targets" are tracked by one or a set of cameras. By setting a trigger level on the position of the "targets", the therapist decides when the beam is disabled.
Several FDA approved systems are currently available on the market and they can all be integrated into the IBA Particle Therapy system.
Imaging |
Many of our customers are finding that given the volumes of Particle Therapy patients who will be seen in the facility, the numbers support ready access to imaging equipment. Some recent designs have included on-site PET-CT and MRI; others have included CT and cone-beam IGRT. Whatever the need, IBA can include imaging systems in the overall PT system purchase, should this be our customer's requirement, and will certainly work together with leading medical equipment manufacturers and our customers to ensure complete integration and a satisfactory facility design.
Milling Machines |
Many of our customers fabricate patient-specific beam modification devices with milling machines. The shape and thickness of the devices is determined and exported as data by the treatment planning system.
For our customers requiring milling machines, IBA works with leading manufacturers and will package them together with the core technological components in the overall PT system purchase and ensure complete integration and compatibility between systems.
IBA has all the ancillary equipment necessary to complete your PT facility, ensuring that you have everything needed to get the job done.
