What is a Cyberknife S7 Robotic Radiation Therapy ?
CyberKnife S7 is a fully non-invasive radiotherapy that delivers high-dose, conformal beams to tumors throughout the body—brain, spine, lung, liver, pancreas, kidney, and prostate—offering an option when surgery isn't feasible.
A compact linear accelerator mounted on a robotic arm treats from hundreds of angles with sub-millimeter accuracy; integrated real-time imaging and motion tracking continuously adjust beams for moving targets.
Most treatments are brief outpatient sessions (typically 1-5 visits) with personalized planning, frameless workflows, and optional fiducials to maximize tumor control while sparing healthy tissue.
What Makes CyberKnife S7 Unique?
Unrivaled Accuracy
The CyberKnife S7 system can treat moving tumors with pinpoint accuracy that other radiation therapy systems cannot match. This is especially important when treating tumors that move in response to any bodily function (e.g., breathing).
Unrestricted Flexibility
The robotic maneuverability of the CyberKnife S7 system enables doctors to deliver highly personalized treatments. CyberKnife S7 clinicians at Valentis can select various angles targeting the tumor with a high dose of radiation from every conceivable angle.
Real-time Image Guidance
The CyberKnife S7 employs a sophisticated 6D image guidance system to track and adjust treatment in response to any movement of the patient or tumor.
Convenient Treatment
Depending on the type of tumor, patients typically require one to five CyberKnife S7 treatments, which typically last less than 30 minutes, whereas other radiation systems require dozens of treatments spread out over several weeks.
Patient Safety
The CyberKnife S7 is a fully integrated closed-loop system, unlike other gantry-based linear accelerators. Each function collaborates to provide the safest possible patient experience.
What Conditions Cyberknife S7 Can Treat?
CyberKnife S7 provides precise treatment for various types of tumors across different parts of the body
Brain Tumor
CyberKnife S7 is used as a boost for residual or recurrent cases of malignant gliomas or glioblastomas after surgery. Neuromas arising from other nerves, pituitary adenomas, hemangioblastomas, meningiomas, and hemangiopericytomas are all potential candidates.
Spinal Tumor
Precise treatment of spinal tumors with sub-millimeter accuracy, protecting the spinal cord and surrounding critical structures.
Prostate Cancer
Non-invasive treatment option for prostate cancer with minimal side effects and excellent outcomes.
Pancreatic Cancer
Stereotactic radiotherapy can deliver highly focused, high-dose treatment to selected pancreatic tumours, offering a non-invasive option to improve local control, relieve symptoms, and potentially downstage disease. It is typically used as part of a multidisciplinary plan alongside chemotherapy or surgery when appropriate, with careful planning to protect adjacent organs such as the stomach and intestines.
Liver Tumors
Effective treatment for liver tumors including hepatocellular carcinoma and liver metastases.
