for positioning patients in radiotherapy


The AIO set facilitates and improves treatments by minimizing possible changes in the patient’s position. With one base plate and different sets of cushions and thermoplastic masks, all parts of the body are positioned and immobilized in a comfortable, precise and reproducible way.

These advanced immobilization techniques enable IMRT and IGRT procedures for almost all anatomical sites, including breast and lung. The base plate for pronation (yellow set) and the base plate for the abdomen and pelvis (green set) were introduced into clinical use in 2021.

Daily patient placement is facilitated. Cushion positioning is simply and reproductively during each fraction. Indexing makes it easy, using a combination of cushions.

Patient comfort is a priority. Soft ecologically designed cushion which allow minimal pressure on the parts of the body that are in contact with cushion.

Made to last. Radiotherapy departments with a large number patients require high-durability medical devices to in order to prevent rough handling.

Maximizes clearance, minimizes collision. The whole AIO set up fits into a CT simulator with a small gentry opening and reduces the risk of collisions with gentry.

Immobilization option without base plate. Cushion can be placed on therapeutic table and without base plate.

SRS-Fix Solution

Because SRS treatment protocols put higher demands on patient immobilization, Orfit tailored a unique fixation solution to support greater precision and daily reproducibility. SRS-Fix is simple to use and very reliable, but most importantly, it offers superior stability for immobilizing a patient’s head.


Easy, fast, trouble-free mask preparation and setup – Unlike other immobilization systems, Orfit provides a single shell, multi-point mask so the molding procedure is very quick. This significantly reduces set-up time so that patient simulation and treatment can commence quickly. The BiteFix device is minimally invasive and helps to further reduce pitch movement.

Highly advanced thermoplastic material – Orfit’s proprietary nanotechnology provides excellent immobilization and fixation without compromising patient comfort. It’s the perfect balance of rigidity matched to comfort, while still offering incredibly low shrinkage.

High precision and reproducibility – The SRS-Fix Solution molds very carefully to the unique definition of the patient’s head in a highly reproducible way. This high precision positioning solution not only helps create a better clinical effect but also delivers more personalized care for these types of advanced treatments.

Operates with existing hardware – Orfit engineered this solution to be compatible with the high precision base plate and head supports to ensure that investment costs would be very low or non-existent. Interoperability is a cornerstone of everything we do.



The integration of MR imaging in radiation therapy facilitates real time motion management.

The CIRS Zeus MRgRT Motion Management QA phantom is designed to address such needs. Zeus is safe for use in an MR environment due to the use of piezoelectric motors and nonferromagnetic materials. The two piezoelectric motors move a cylindrical insert, which contain A tracking target, through a gel/ liquid fillable body by rotating it independently from the motion in the Inferior-Superior direction.

The moving insert contains an organic shaped target (tumor) filled with gel, which is surrounded by the same background gel used to fill the body. The body represents a heterogenous background due to simulated lungs, liver, kidney and spine. The simulated organs are anatomical in shape and have a lifelike spatial relationship. They are filled with gels that provide contrast in CT and MR versus the background gel, which fills the void between the organs. Besides imaging, all organs, except for the lungs, offer ion chamber dosimetry cavities, which allow for completing an entire QA process; from imaging to planning to verification of dose delivered.

Zeus is designed as a single unit with a piezo actuator fixed permanently to a base plate on which the MRI body “snaps”. This allows for quick setup, removal, filling, and storage purposes. The phantom’s base plate has machined slots on the bottom, which allow for the use of indexing bars for precise and repeatable/reproducible phantom-MRI (MRI-Linac) alignment.

CIRS Motion Control software drives this phantom as well as the other phantoms from the CIRS dynamic family. In addition to multiple built-in motion profiles, which are more appropriate for commissioning and routine QA, the software allows for import of complex patient specific respiratory waveforms. These waveforms can be edited for amplitude, sample rate, cycle time, phase shift and baseline position. It also allows to setup independently controllable waveforms for linear and rotation motion of the insert. The Inferior-Superior motion of the insert/moving target can be gated based on amplitude to allow verification of beam latency. The motion controller box provides an interface (BNC
physical input type) for the Beam-on Beam-off signal, which is read by the Motion Control software to calculate the Beam Latency specific to hybrid MRI-Linac systems.

X-ray Therapy

Benefits of X-ray Therapy

For your Patient:

  • Non-surgical approach with proven clinical results
  • Non- invasive treatment procedure with greater wound healing benefits

For your Department:

  • Reduces the patient workload on the linear accelerator
  • Often the patients are elderly, so treatment set up is easier, safer and more comfortable
  • Small footprint enables the room to be dual modality

For your Physics team:

  • Removes the need to commission electron energies and electron cut outs for skin patients

With Image-Guided Brachytherapy


With Image-Guided Brachytherapy (IGBT), clinicians are able to modify dose distributions based on a patient’s individual anatomy and tumor response, typically using CT, PET/CT, and/or MRI. The challenge with imaging, using one or more modalities, is ensuring applicator/needle displacement does not occur when moving the patient to the brachytherapy suite.

The Zephyr HDR utilizes patented hover technology for patient transfer which effectively minimizes the displacement of the applicator/needles between imaging and treatment in a safe, accurate, and stable manner.

Benefits of the Zephyr HDR Solution

  • Incorporate IGBT Treatment planning for GYN and prostate procedures.
  • Improve accuracy of HDR treatment.
  • Reduce staff requirements and injuries.
  • Utilize in CT, PET/CT, and/or MR.
