Dr. and Sara Cavey sitting behind the Radixact machine.
At Texas Radiotherapy, our people are only matched by our technology. Being family-owned, we review and select the technology ourselves. We choose the same type of technology that many research and university-led centers use. We offer excellent treatment within a warm and family-like environment.
Not all radiation therapy technologies have the same capabilities. Our chosen technology utilizes recent advancement with proven clinical outcomes, reduced side effects and shortened treatment times.
At Texas Radiotherapy, we only use state-of-the-art technology to help our patients conquer cancer.
Dr. Cavey personally selects all technology that is used, and he and his very experienced team interpret the data related to your care, to maximize your outcome.
Here are the key types of treatment technologies that Dr. Cavey uses:
Dr. Cavey uses external beam radiation through an advanced treatment system with the Radixact by Accuray.
The Radixact delivers high-energy beams precisely to the tumor location to destroy cancer cells.
Dr. Cavey also utilizes real-time tumor tracking during SBRT, IMRT and VMAT through the use of Synchrony. Only 5% of LINACs in the U.S. can track a moving target, and the Radixact with Synchrony delivers against a moving target (tumors can move slightly as you breathe or change position).
Here are the types of external beam radiation that Dr. Cavey uses:
Intensity Modulated Radiation Therapy (IMRT)
SBRT, SRS and SABR
Image Guided Radiotherapy (IGRT) with a linear accelerator (LINAC)
Volumetric Modulated Arc Therapy (VMAT)
Adaptive Radiotherapy (ART)
Dr. Cavey is an expert and one of the top doctors in the U.S. for low dose brachytherapy.
Low Dose Brachytherapy
Dr. Cavey and Sara Cavey worked together to select their key precision technology platforms. They selected technology that excels at cancer treatment.
Function: Dose Delivery
How It Works: Delivers continuous 360-degree radiation beams shaped precisely to the tumor.
Key Patient Benefit: Pinpoint Accuracy — Maximizes radiation directly to the tumor with sub-millimeter accuracy.
The technology in the field of radiation therapy progressed from IMRT to VMAT (Volumetric Modulated Arc Therapy) in the early 2000’s. With this technology, radiation is delivered using a beam that continuously rotates around the patient. The resulting plans are improved as compared to IMRT and the treatment times are shorter.
At Texas Radiotherapy, our linear accelerator is a Radixact from Accuray, the next generation Tomotherapy introduced in 2016. The Radixact delivers external radiation therapy in an even more advanced fashion than the VMAT delivered by other linear accelerators in the market. With the helical delivery of the Radixact, a patient’s treatment is much more precisely delivered; high-doses are better confined to the target and dose to the surrounding normal tissues is reduced even further.
Function: Real-Time Motion Tracking
How It Works: Continuously tracks tumor motion and adjusts the radiation beam in real-time.
Key Patient Benefit: Comfort & Freedom — Allows natural, comfortable breathing during treatment without requiring rigid immobilization.
Target tracking and automatic, real-time motion synchronization for the Radixact System® using Artificial Intelligence.
Over 15 years ago, Accuray revolutionized tumor and patient motion management with our Synchrony® real-time motion synchronization technology. With more than a decade of clinical proof behind Synchrony for the CyberKnife System, Accuray now brings Synchrony® to the Radixact® System. While others will use gating or other uncomfortable methods to try and compensate for motion, our Synchrony radiotherapy treatment planning technology actively tracks and corrects for it — automatically, continuously and in real time. This ultra-precise personalized adaptive delivery can help to improve clinical outcomes and reduce radiation therapy side effects, while potentially shortening treatment times.
Confidently maximizes the dose delivered to the target, minimizes dose to healthy tissue — knowing that treatment delivery will automatically account for target movement — to improve treatment efficacy and enhance long-term cancer control.
Minimize margins and ensure that target or patient movement does not result in irradiation of surrounding healthy tissues and organs at risk, reducing side effects and giving patients a better quality of life during and after treatment.
Enable truly continuous treatment delivery — no gated treatment delivery or interruptions for patient repositioning — to optimize clinical efficiency. Shorten treatment times and eliminate the need for patient restraints and breath-holds to reduce discomfort and improve the overall patient experience.
Function: High-Definition 3D Imaging
How It Works: Produces clear, high-resolution 3D scans before and during every session.
Key Patient Benefit: Clear Targeting & Fast Setup — Removes image blur so your team can rapidly verify your exact positioning and anatomy each day.
ClearRT will produce clear, high-fidelity kVCT images to provide soft-tissue visualization and clinical capabilities like no other radiation therapy system in the world.
Function: Adaptive Treatment Planning
How It Works: Monitors daily anatomical changes like weight loss or tumor shrinkage.
Key Patient Benefit: Personalized Adjustments — Automatically alerts doctors if your treatment plan needs updating to prevent under-dosing.
PreciseART® makes adaptive radiotherapy simple and practical for every practice, bringing enhanced precision and continuously personalized treatments to more patients. Fully integrated daily re-imaging, patient data analysis and automated reporting empower treatment teams to continuously monitor every patient, identify patients that will benefit from re-planning and efficiently adapt plans in real time.
Function: Re-Treatment Planning
How It Works: Evaluates prior radiation doses to safely design new treatment plans.
Key Patient Benefit: Safe Future Care — Enables fast, safe re-treatment planning if radiation is ever needed again in the same area.
PreciseRTX® accelerates and automates the re-planning process to make re-treatment more efficient for practices and more effective for patients. Intelligent integration enables importation of previous treatment plan data from Accuray and non-Accuray systems, and automatically deforms previous treatment plan contours and previously delivered dose onto the new treatment planning CT image. By deforming the prior data sets, much more accurate, effective and safe retreatments are possible than with other systems that lack this capability.
