Deviceless 4D offers the following benefits:

Deviceless workflow.
It is an alternative and efficient solution for 4D imaging and virtual simulation―without an external device. It eliminates the need for the sometimes complex and time-consuming exam specific set-up when using an external respiratory monitoring device.

Fewer parts–no maintenance.
No connection, maintenance or parts issues, no time-consuming set-up and no added hassles; built-in functionality offers inherently high reliability.

Precise measurement.
It uses internal anatomical metrics directly from the image data to determine the breathing signal in real time for precise visualization of tumor and organ motion. It combines amplitude and phase binning for optimal 4D CT image quality results.

Protocol-driven workflow.
Using the same simple, efficient, protocol-driven 4D workflow for all patients, Deviceless 4D enhances productivity and enables shorter 4D CT examination times. It enables clinicians to set up and scan with just a few clicks of the mouse.

Designed for patient comfort.
No belts, blocks, or markers touching the patient.

Next-generation, device-free technology enables improved workflow productivity while delivering superb image quality.

The best of phase-based and amplitude-based binning.
Traditional 4D imaging solutions have utilized one of several sorting methods―with phase-based and amplitude-based binning being the most prevalent. Deviceless 4D combines the benefits of both phase and amplitude binning, sorting by time of image acquisition and by amplitude of the motion trace. This unique method helps achieve excellent 4D CT image quality results required for radiation therapy planning.

Measures internal anatomical metrics.
Rather than tracking external changes on the body due to breathing, Deviceless 4D uses internal anatomical metrics directly from the image data to determine the breathing signal. This gives clinicians a clear picture of how internal anatomy is moving in time, to precisely target tumors while sparing healthy tissue.

Seamless―from start to finish.
Deviceless 4D calculates the patient’s breathing cycle length prior to the CT simulation, automates the sorting of 4D CT images into the desired respiratory bins, creates intensity projection datasets (e.g. MIP) and makes them available for virtual simulation. This makes the entire 4D process easier than ever before.
