ProCline™ Prone Breast Radiotherapy Positioning

Lightweight Prone Breast Positioning Designed for Efficient, Comfortable Radiotherapy

ProCline™ is a prone breast radiotherapy positioning system designed to support efficient, reproducible patient setup while prioritizing the daily workflow and physical demands of the Radiation Therapist.

Unlike traditional prone breast boards that can be bulky and time-consuming to adjust, ProCline™ is intentionally engineered to be lightweight, intuitive, and quick to configure, enabling faster patient positioning, safer handling, and smoother transitions between patients—while supporting the clinical precision required for modern breast radiotherapy.

ProCline™ is well suited for both whole breast and partial breast treatment workflows, where comfort, stability, and consistency are essential.

Clinical Precision Matched to Breast Radiotherapy Needs

Adjuvant radiotherapy to the breast in the prone position has been shown to significantly reduce the amount of irradiated lung and heart volume in patients with left breast cancer when compared to treatment in the more traditional supine position. If prone positioning better protects normal tissue adjacent to the breast, the risks of long-term deleterious effects of radiotherapy may be reduced. 

In combination with IMRT and VMAT techniques (including non-coplanar fields), treatment plan options are significantly improved in both hypofractionated and partial breast treatments.

The system provides accurate, repeatable positioning while remaining easy to use.

ProCline

Designed for the Radiation Therapist

Prone breast setups can be physically demanding and time-intensive. ProCline™ is designed to reduce that burden.

By simplifying the setup process, ProCline™ helps therapists maintain efficiency and consistency throughout the treatment day.

Therapist-focused design features

Lightweight construction

Lightweight construction for easier lifting, placement, and removal

Intuitive setup

Simple, intuitive adjustments that reduce setup complexity

Fewer components to handle

Fewer components to handle during patient positioning

Faster changeovers

Faster changeovers between patients and fraction setups

Reduced physical strain

Reduced physical strain during prone positioning workflows

Lean, Repeatable Prone Workflow

ProCline™ supports a lean prone breast workflow that reduces unnecessary steps while maintaining reproducibility.

The result is a system that supports predictable setup times and improved daily throughput.

Workflow Advantages

Indexed positioning

Indexed positioning to support consistent setup across fractions

Adjustable positioning

Adjustable positioning to accommodate patient anatomy without complex reconfiguration

Reduced need for repositioning

Reduced need for repeated repositioning during simulation and treatment

Efficient transitions between cases

Efficient transitions between prone and non-prone cases

Integrates with common workflows

Designed to integrate into IGRT and SGRT workflows where applicable

Patient Comfort & Safety

Patient comfort plays a critical role in prone breast radiotherapy. ProCline™ is designed to balance support, stability, and comfort to encourage patient compliance and reduce movement.

By improving comfort and stability, ProCline™ contributes to safer and more consistent treatments.

Patient-Focused Benefits

Supportive prone positioning

Supportive prone positioning to improve patient tolerance

Stable geometry

Stable geometry to minimize unintended movement

Reduced pressure points

Design that reduces pressure points during treatment

Comfort through longer treatments

Comfort that supports longer treatment sessions when required

Compatibility

CDR Systems positioning and immobilization solutions are designed to integrate into modern radiotherapy environments, including gantry-based and bore-based systems, and to support common clinical workflows such as CT (including 4D-CT where applicable), MRI (where applicable), PET-CTon-board imaging (kV/MV, CBCT), and SGRT, across techniques including IMRT, VMAT-TBI, SRS, SBRT, and related approaches.

Intended Users

ProCline™ is intended for use by Radiation Therapists and Radiation Oncology teams performing prone breast radiotherapy.

ProCline™ simplifies prone breast positioning by combining lightweight design, efficient setup, and patient-centered comfort—helping therapists deliver precise breast radiotherapy with less physical strain and greater consistency.
