Introduction
The ZAP-X gyroscopic radiosurgery system delivers high-dose focused radiation to selected brain and head–neck lesions using a self-shielded platform that rotates beam angles to spare healthy tissue—non-surgical “radiosurgery,” not open brain operation.
Availability is center-specific. Educational summary—not for all tumors; differs from Gamma Knife/Linac systems; no cure/cost guarantee.
Why it is done / when it is considered
ZAP-X Gyroscopic Radiosurgery System is commonly discussed in situations such as:
- Selected brain metastases or benign intracranial tumors
- AVM or other lesions where focused radiation fits plan
- Non-invasive option when open surgery risk is high
- Recurrent/residual disease per oncology team decision
How the procedure is done
- Imaging-based planning with head immobilization/mask
- Gyroscopic arms deliver radiation from many angles
- Often frameless; single or few fractions case dependent
- No incision; same-day or brief observation then home
Preparation
- Recent MRI/CT; list medicines and implants (pacemaker etc.)
- Report pregnancy—radiation must be avoided
- Discuss steroids and smoking/diabetes control
- Expect gradual lesion response—not instant disappearance
Risks and possible complications
Risks differ by procedure. Your age, other illnesses, and anaesthesia plan change the picture—your care team will explain what applies to you.
- Brain swelling, headache, seizures, neurologic symptoms
- Radiation necrosis or effect on critical nearby structures—uncommon/case dependent
- Limited hair loss at site, fatigue, local skin reaction
- Incomplete control or need for other treatment later
Recovery
- Many resume daily activities quickly per team advice
- Steroids may taper slowly; driving limited if seizure risk
- Follow-up imaging tracks response over months
Aftercare and follow-up
- Emergency care for severe headache, vomiting, weakness, seizures
- Keep neuro-oncology and MRI schedule
- Take antiseizure/steroid medicines as prescribed
- Report new neurologic symptoms without delay
Frequently asked questions
Is this Gamma Knife?
Same radiosurgery concept; hardware and workflow differ—ask which system your center uses.
No incision means no risk?
No. Radiation and swelling risks remain—just no surgical cut.
For all brain tumors?
No. Size, number, location, and tumor type guide team choice.
