The SDX® System’s unique ability to pair a patient’s inspiration rate and lung volume measurement with clear visual biofeedback makes it possible to maximize the stability of internal organs and the tumor treatment zone. This allows for an increased dose to the tumor with decreased toxicity to vital organs. SDX® is a spirometry based system for managing thoracic and abdominal tumor motion during imaging and radiation therapy.
MOVING TUMORS Extremely accurate targeting is critical. Adverse effects are still common due to difficulty in sparing surrounding tissue. Though camera systems are easy to use, their main strength is patient positioning prior to treatment. But to what extent is the movement of the thorax a true reflection of what’s happening internally?
SDX SYSTEM SDX Respiratory Gating System is a unique spirometry-based motion management and gating system. A solution for IMRT, ARC, SBRT and Proton Therapy, SDX is ergonomic, portable, affordable and easy-to-use for therapists and patients. SDX instantly and significantly improves the accuracy, safety and quality of radiation therapy for breast, lung, liver or any tumor affected by respiratory motion.
Reducing tumor motion during imaging and treatment
Enhancing tumor imaging and visualization
Reducing treatment margins
Increasing dose with decreased toxicity to vital organs
Repositioning vital organs out of the high dose region
Enhanced imaging, reduced margins, increased dosing. SDX is an affordable, extremely effective solution for thoracoabdominal lesions. Real-time internal information ensures millimetric precision while sparing critical structures and healthy tissue. SDX is excellent as a stand-alone solution for imaging and treatment, or as a complement to camera systems to increase accuracy.
Designed for patient relaxation, confidence and engagement. With SDX, patients remain in complete control of their breath throughout treatment. A dedicated patient screen guides patient breath holds with simple visualizations and familiar, calming imagery. Many patients also find their active involvement to be an important motivating factor in successfully completing treatment cycles.
4D-CT reconstructions are often degraded due to poor abdominal motion. Compared with external systems, the respiratory signal obtained with the SDX® spirometer provides a high quality volumetric amplitude that is ideal for managing Free Breathing 4D-CT. The Gating Module links the SDX® to the scanner, driving 4D-CT acquisition. The Gating Module receives the two signals, X-Ray on and X-Ray off, defining the acquisition period. The resulting high quality respiratory data allows for superior 4D-CT reconstructions.
The Gating Module continuously monitors the patient’s breathing and adjusts for motion in real time, delivering the dose only when the patient is in the breath hold zone. If the patient’s breath hold moves beyond the defined breath hold zone, the Gating Module signals the equipment to immediately pause the radiation beam; when the patient moves back into the breath hold zone, the equipment is triggered to resume the radiation. The Gating Module allows the patient to return to the defined breath hold zone as many times as required to complete the daily radiation plan.
