The Zephyr Patient Positioning and Transfer System
Simplify MR-guided brachytherapy with the Zephyr® Patient Positioning and Transfer System
Advancements in technology make brachytherapy a highly effective option for destroying cancer cells, but accurate patient and applicator positioning is essential to minimize the chance of radiation toxicities. The Zephyr Patient Positioning and Transfer System makes it easy and efficient to set up, scan, plan, transfer, and treat patients in the same position — keeping the patient comfortable, while minimizing the risk of movement.
Advance treatment accuracy with MR Imaging or CT Imaging
The imaging modality traditionally used in radiation oncology is computed tomography (CT) imaging. Because a tumor and surrounding soft tissue organs have similar physical characteristics, it can be very difficult to identify a tumor’s boundary. MR Imaging is unique, in that it can be used to determine the boundary of a tumor and other soft tissue very accurately. The accuracy and precision required to safely deliver radiation therapy make this an even more challenging feat.
MR Imaging is unique, in that it can be used to determine the boundary of a tumor and other soft tissue very accurately. The high magnetic field required to create an MR image can, however, make it challenging to deliver a patient treatment. This is where the Zephyr system offers a solution.
Deliver better treatment with the Zephyr Patient Positioning System
Zephyr makes it easy to transfer a patient from a treatment room to an MR imaging suite and back again, while keeping the patient in the position required for treatment. A Zephyr system consists of a hoverboard, blower, and stretcher, which together allow the patient to be transferred onto and off an MR couch top.
What a treatment with Zephyr looks like
A typical treatment procedure would start with the patient being positioned on a Zephyr HDR Hoverboard using MR safe positioning devices and stirrups. Once positioned, a physician can place a brachytherapy treatment applicator, which will be used to guide the radiation source to the tumor during treatment.
Once the applicator is in place, the patient is transferred onto a Zephyr stretcher and moved to the MRI. When imaging has been completed, the process is reversed— the patient is brought back to the treatment room and the treatment is delivered. The Zephyr system allows clinicians to use more accurate MR imaging to deliver a more precise treatment, while ensuring that the patient is comfortably supported in the treatment position during the entire setup, imaging, and treatment process.
Improve staff safety with the Zephyr Patient Positioning System
Traditionally, if a patient needed to be transferred onto an imaging table, a pad or sheet would be placed under the patient. A group of several nurses or therapists would be required to drag the patient from one table to another. Not only would the movement jostle the patient out of position, but there would also be a risk of injury for the clinical staff.
With the patented Zephyr hover technology, a single nurse can easily float a patient between a stretcher and an imaging or treatment table, minimizing the risks of patient movement and discomfort. Moving even your largest patients couldn’t be easier or more efficient.
MR-Guided Brachytherapy with Zephyr HDR
The Zephyr HDR system utilizes patented hover technology to allow patient transfer from imaging to treatment while maintaining patient positioning and minimizing the risk of needle/applicator displacement. Integrating the Zephyr HDR for your brachytherapy procedures allows the incorporation of valuable 3D dosimetric data from CT/MR imaging, providing more accuracy in today’s brachytherapy procedures.
