For Patients · What to Expect

From first call to follow-up — the whole journey, demystified.

Radiosurgery sounds intimidating. The experience isn't: no incisions, no anesthesia, no hospital stay — most patients are surprised by how uneventful treatment day feels. Here is exactly what happens at each step.

Step 01
Day 0

First contact & records review

Call (321) 972-1102 or send a consultation request. Our team gathers your records and recent imaging — we can pull from most imaging portals, or you can bring discs. Dr. Thomas reviews everything personally before you're asked to travel anywhere.

If we're not the right treatment for you, we'll tell you at this stage — and point you toward what is.

Step 02
Within ~1 week

Consultation

A real conversation with the physician — your history, your imaging on screen, what treatment would target, expected results, side effects, and every alternative (including doing nothing). Bring family, bring questions; nothing is rushed.

Out-of-town patients can often complete this step by phone or video before traveling.

Step 03
~1–2 weeks

Simulation & planning

A short "mapping" visit: high-resolution imaging in the exact position you'll be treated in, plus a custom immobilization device — for brain treatments, a light mesh mask molded to your face (not a bolted frame; no head shaving).

Then our physician–physicist team builds and quality-checks your plan: the target is contoured slice by slice, every nearby critical structure is fenced off, and the plan is verified on the machine before you return. For prostate SBRT, SpaceOAR® placement and fiducial markers happen in this window too.

Step 04
1–5 sessions

Treatment day

Wear comfortable clothes; eat normally; take your usual medications unless told otherwise. You'll lie on the table, the team positions you with your mask or supports, and HyperSight™ takes a six-second scan to confirm the target's position before the beam ever turns on.

Then the machine rotates around you. You feel nothing — no heat, no pain, no sound beyond a quiet hum. Most sessions finish in under 5 minutes. Functional radiosurgery — tremor, trigeminal neuralgia — takes longer, up to about 25 minutes; LDRT sessions run 10–15. The team watches you on camera the entire time and can pause instantly if you need it.

Afterward you get up and go about your day. Most patients drive themselves home and have no post-treatment restrictions.

Step 05
Ongoing

Follow-up

Radiation works on biology's timeline, not the calendar's. We schedule follow-up imaging and visits at set intervals, coordinate everything with your referring physicians, and remain one phone call away in between.

When results come, they follow known patterns — see the timelines below.

Honest timelines

When to expect results

LDRT · arthritis & spine
1–2 weeks

Over 80% of patients report significant or complete pain relief within 1–2 weeks of finishing, often lasting months to years.

Pain radiosurgery
24–48 hours

Severe pain syndromes can respond within days of a single session — among the fastest responses in radiosurgery.

Tremor & dystonia
Weeks–months

Improvement is gradual and durable as the target quiets — typically emerging over weeks to months after treatment.

Tumors & metastases
First scan

Tumor control is confirmed on follow-up imaging, usually beginning ~2–3 months after treatment.

Bring to your consultation
Recent imaging (discs, or the name of the facility so we can pull it)
Medication list & allergies
Relevant clinic notes, pathology, or procedure reports
Insurance card & photo ID
A family member or friend, if you'd like a second set of ears
Forms can be completed ahead of time through our patient forms page.
Traveling from out of town?

Because most courses are 1–5 sessions, treatment usually fits in a single short stay near Winter Park / Orlando. We front-load the records review and consultation remotely so your trip is for treatment — not exploration.
