Stereotactic Radiotherapy (SRT)
What Is SRT?
SRT uses detailed 3d imaging, motion tracking, and robotic technology to precisely target tumors while protecting healthy tissue. It’s particularly useful for treating tumours in delicate areas of the brain, spine, or body that require a high dose of radiation over multiple sittings to reduce the risk of complications.
How SRT Works
High-resolution scans (MRI, CT, PET) are used to map the tumor’s exact location.
A custom treatment plan is created to deliver radiation from multiple angles.
Radiation is delivered in small but powerful doses over a series of sessions.
Real-time motion tracking ensures precise delivery, even with slight movements.
Frequently Asked Questions
If your pet is a candidate for SRT, our radiation oncologist will develop an individualized treatment plan specifically for your pet, generally consisting of one to four treatment sessions delivered either daily or every other day.
Your pet undergoes general anesthesia for each treatment to ensure they remain still. SRT is minimally invasive and not painful, allowing us to use much lighter anesthetic drugs than those used for a surgical procedure.
Your pet should fast for at least 10 hours before each therapy session because they will be undergoing anesthesia. Pets may be given water and any previously prescribed medications. When the treatment is complete, they are awake within minutes. We will monitor them closely during and after treatment before they go home with you.
Pets receiving SRT must have “bulky” tumors to effectively receive high doses of radiation to eliminate tumor cells and slow their growth. The location of the tumor is also important as some organs are more sensitive to radiation therapy than others.
To determine if your pet is a candidate for SRT, our oncology team will use computerized imaging (CT) to reveal the surface area and volume of the tumor. Special software defines the tumor and normal tissues, allowing us to precisely identify the treatment area and develop a plan made specifically for your pet.
