ZAP-X Gyroscopic Radiosurgery in Delhi at Apollo Hospitals

ZAP-X gyroscopic radiosurgery brings a new standard of non-invasive brain tumour and neurological care to patients in and around Delhi. Using a dedicated, next-generation radiosurgery system designed specifically for the brain, ZAP-X delivers highly focused radiation to brain tumours and selected neurological conditions without any incision, stitches or prolonged hospital stay. As the first centres in South Asia to offer this advanced technology, Apollo Hospitals Delhi provides patients with a precise, comfortable and convenient alternative to traditional brain surgery and conventional radiation therapy. Here, every treatment plan is personalised and guided by a specialised team of neurosurgeons, radiation oncologists and medical physicists who focus on safety, accuracy and long-term outcomes.

What Is ZAP-X Gyroscopic Radiosurgery?

ZAP-X is a state-of-the-art stereotactic radiosurgery (SRS) system that uses a gyroscopically rotating linear accelerator to deliver high-dose, precisely targeted radiation to a defined area in the brain. Unlike conventional radiation machines that are adapted for the whole body, ZAP-X is purpose-built for intracranial and select head-and-neck conditions. This focused design allows the system to treat brain tumours and other lesions with millimetre-level accuracy while minimising exposure to surrounding healthy brain tissue and critical structures such as the optic nerves, eyes and brainstem.

During treatment, the ZAP-X system moves around the patient in multiple axes, creating hundreds of unique beam paths that converge on the target. At the same time, high-definition imaging and computer-controlled robotics continuously verify the position of the lesion and adjust for even small movements. Patients lie comfortably on the treatment couch wearing a custom-made mask, without the need for invasive headframes or pins. Most sessions take about 15 minutes to 1hour, and treatment is typically performed as a day-care procedure with little or no recovery time.

Who Can Benefit from ZAP-X Treatment?

ZAP-X radiosurgery in Delhi is suitable for many patients who require precise, localised treatment to brain or cranial lesions but either wish to avoid open surgery or are not ideal candidates for it due to age, medical conditions or tumour location. It may be considered in the following situations:

• Patients with small to medium-sized benign brain tumours such as vestibular schwannomas (acoustic neuromas), pituitary adenomas or meningiomas, including incidentally detected or post surgical residue
• Patients with brain metastases (cancers that have spread to the brain from other parts of the body).
• Individuals with arteriovenous malformations (AVMs) where focused radiation is needed to seal abnormal blood vessels.
• Vascular Tumours: Cavernomas, glomas etc
• People with medically refractory trigeminal neuralgia experiencing severe facial pain despite medications.
• Selected patients with movement disorders such as essential tremor or tremor-predominant Parkinson’s disease who are not suitable for invasive surgery.
• Patients who have already undergone surgery or radiation and require further localised treatment in a safe, controlled way.
• Select cases of recurrent gliomas

The decision to use ZAP-X is always made after detailed evaluation by a multidisciplinary team at Apollo Hospitals Delhi, taking into account your clinical condition, imaging findings and overall health.

Key Benefits of ZAP-X at Apollo Hospitals Delhi

ZAP-X offers several advantages over traditional surgery and older radiosurgery systems, especially when delivered in a specialised neurosciences environment like Apollo Hospitals Delhi.

• Non-invasive and frameless: No incisions, stitches or invasive headframes. A comfortable mesh mask keeps the head steady during treatment. :
• Short treatment sessions: Most treatments are completed in approximately 30 minutes, with many patients needing only a single session.
• Outpatient procedure: In most cases there is no need for hospital admission or overnight stay; patients are able to return home the same day.
• High precision and safety: An integrated imaging system and real-time monitoring help ensure accurate targeting, while automatic safety checks pause treatment if any parameter is out of range.
• Minimal radiation exposure to healthy brain tissue: The unique gyroscopic delivery and advanced planning software help minimise radiation dose to critical structures such as the brainstem, eyes and optic nerves.
• LINAC-based, self-shielded system: ZAP-X uses a modern linear accelerator instead of Cobalt-60, and its self-shielded design significantly reduces radiation leakage—almost 50 times lower than many conventional systems—enhancing safety for both patients and staff.
• Patient-centric environment: The treatment room is designed for patient comfort, and the care team remains close by throughout the procedure for support and monitoring.

Your ZAP-X Treatment Journey at Apollo Hospitals Delhi

At Apollo Hospitals Delhi, your ZAP-X experience is guided at every step by a dedicated team, including a Patient Navigator who coordinates appointments and provides support throughout the process.

1. Initial consultation

You will meet a neurosurgeon and/or radiation oncologist who will review your medical history, MRI/CT scans and current symptoms. They will explain whether ZAP-X is suitable for you, discuss potential benefits and risks, and answer your questions.

2. Simulation and mask creation

At a simulation appointment, a custom mesh mask is created to gently support your head. A CT scan (sometimes with contrast) is performed in the same position as treatment to map the exact area to be targeted.

3. Treatment planning

Using your simulation scans and MRI images, neurosurgeons, radiation oncologists and medical physicists design a personalised treatment plan. The aim is to deliver a high dose to the lesion while keeping surrounding normal brain tissue as safe as possible.

4. Treatment day

You arrive as a day-care patient, lie on the treatment couch and wear your personalised mask. The team positions you correctly, confirms alignment with on-board imaging and starts the treatment. The ZAP-X system moves around your head to deliver radiation from multiple angles. You do not feel the radiation; most patients report no pain or discomfort during the session.

5. Post-treatment and follow-up

After treatment you are usually observed briefly and then allowed to go home. Follow-up visits and scans are scheduled to monitor response, assess symptom improvement and adjust any medications if required.

Cost of ZAP-X Treatment in Delhi

The cost of ZAP-X treatment in Delhi depends on several factors, including the type and size of the lesion, the complexity of treatment planning, the number of sessions recommended, and any additional imaging or supportive care required. Because each patient’s condition is unique, it is not possible to provide a standard figure that applies to everyone.

At Apollo Hospitals Delhi, the team aims to offer clear guidance and transparent information once your case has been evaluated. You will have an opportunity to discuss expected costs, insurance coverage, and available payment options with the hospital’s financial counsellors and care coordinators before starting treatment.

Frequently Asked Questions (FAQs)

Is ZAP-X treatment available in Delhi?

Yes. Apollo Hospitals Delhi is one of the select centres in South Asia to offer ZAP-X gyroscopic radiosurgery, providing patients in Delhi and neighbouring regions access to this advanced non-invasive brain treatment.

Is ZAP-X treatment painful?

No. ZAP-X radiosurgery is a non-invasive procedure. You do not feel the radiation, and there are no cuts, stitches or invasive headframes. Most patients report that the session is comfortable, and some even feel relaxed enough to rest during treatment.

Will I need to stay in the hospital after ZAP-X?

In most cases, ZAP-X is done as an outpatient or day-care procedure. After a short period of observation, you can usually go home the same day. Your doctor will advise if any special monitoring is required based on your overall health.

How many ZAP-X sessions will I need?

Many patients complete treatment in a single session. However, in certain situations your doctor may recommend two or three smaller-dose sessions to balance effectiveness and safety. This will be explained during your planning discussion.

Are there side effects after ZAP-X?

Most patients experience minimal side effects. Some may notice mild fatigue or a light headache for a short period after treatment. Serious complications are uncommon because ZAP-X is designed to limit radiation to normal brain tissue. Your care team will discuss possible risks relevant to your specific condition.

Is ZAP-X safe for elderly patients or those with other health problems?

Yes, ZAP-X can be an excellent option for elderly patients or those with medical conditions that make open surgery risky. Because it is non-invasive and does not require general anaesthesia in most cases, it often offers a safer alternative for such individuals.

Can I have ZAP-X if I have already had brain surgery or radiation?

In many cases, yes. ZAP-X may be used to treat residual tumours, recurrent lesions or new metastases even in previously treated areas, provided it is safe to do so. Your specialists will review your prior treatments and imaging before making a recommendation.

Will I lose my hair after ZAP-X?

Hair loss is unlikely with ZAP-X because the radiation beams are very focused and do not typically affect large areas of the scalp. If a lesion is close to the surface, there may be a small, localised area of thinning, which your doctor will discuss with you beforehand. Most of the time rare and reversible

How soon will I see results from ZAP-X treatment?

The timeline varies by condition. For tumours, the goal is often to stop growth or gradually shrink the lesion over months, which is monitored using follow-up MRI or CT scans. For trigeminal neuralgia, pain relief may begin within weeks, though in some cases it can take longer.

Can I continue my regular activities after ZAP-X?

Most patients can return to normal light activities within a day, unless advised otherwise. Heavy physical exertion or travel plans should be discussed with your doctor depending on your condition and overall health.

How do I know if ZAP-X is right for me?

The best way to determine suitability is to schedule a consultation at Apollo Hospitals Delhi. Your medical team will review your reports, examine you and discuss all available options—including ZAP-X, surgery, conventional radiotherapy or a combination—so that you can make an informed decision.
