The Spatial Interpretation Challenge in Radiation Therapy

In radiationtherapy, precision is critical. Clinicians must deliver an effectivedose to the tumor while protecting surrounding healthy tissue. That requires aclear, three-dimensional picture of the patient's anatomy.

 

However, current treatmentplanning still relies heavily on 2D cross-sectional images. Clinicians mustmentally reconstruct complex 3D spatial relationships from numerous CT andMRI slices. Physicians trace tumor boundaries slice by slice, while physicistscross-check dozens of images to ensure full target coverage withoutcompromising critical organs. For complex cases, particularly those nearcritical structures, this "inferring 3D from 2D" processimposes a significant cognitive burden, making interpretation more difficultand often prolonging interdisciplinary discussions.

 

To address thislimitation, we collaborated with Hualien Tzu Chi Hospital to build the world’sfirst glasses-free 3D Smart Educational Training and Decision SupportPlatform for Radiation Oncology Treatment, enabling clinicians to see whatthey previously had to imagine.

 

The Real-World Impact on Clinical Workflow

Before adopting our technology, theradiotherapy team faced the following bottlenecks:

  • Interpretation burden and dose coverage blind spots
        Physicians and physicists must repeatedly compare 2D slices to infer 3D relationships. Complex lesions make dose distribution difficult to confirm, sometimes leading to overlooked coverage gaps.
  • High cross-team communication cost
        Different professionals spend extra time aligning spatial understanding, slowing decision-making.
  • Difficulty in teaching and experience transfer
        Junior physicists require extensive training to develop reliable 3D spatial understanding, often taking months before they can confidently evaluate treatment plans.

Overall, the spatial understanding gapinherent in 2D imaging not only increases clinical workload but may also affectthe efficiency of treatment plan review and the quality of cross-teamcommunication.

 

Solution: Lixel SpatiumNEX RTSS Glasses-Free 3D SmartEducational Training and Decision Support Platform

Hualien Tzu ChiHospital adopted the Lixel SpatiumNEX RTSS Platform, which convertsradiation therapy plans into intuitive 3D visualizations. This enablesclinical teams to quickly understand the spatial relationships amongtumors, organs at risk, and dose distributions.

Core features of the platform include:

  • Glasses-free 3D light-field display: Enables intuitive viewing of tumors, organs at risk, and dose distribution     without the need for wearable devices.
  • Mid-air gesture control: Rotate, slice, and measure images with simple mid-air hand gestures for plan     review.
  • AI-powered medical image segmentation and 3D reconstruction: Integrates CT and RT dose images to present complete three-dimensional dose distributions.

Results: Measurable Gains in Speed, Consistency, and Safety

After implementing the glasses-free 3Dplatform, clinical data showed significant efficiency and safety improvements:

✅Faster planning. Lessexperience dependency.

●     50% reduction in planningtime: Average review time shortened by half,greatly accelerating clinical workflows.

●     76% improvement inconsistency: The time gap between senior and juniorphysicists dropped from 67 minutes to just 16 minutes, significantly improvingplanning consistency.

 

✅Fewer blind spots. Greaterpatient safety.

●     Precise tumor coverage: Ensures full dose coverage of tumor margins, reducing recurrencerisk.

●     Critical tissue protectionverified: Clearly confirms that adjacent tissuesare within safe limits, effectively preventing potential treatment blind spotsand enhancing overall safety.

Conclusion: Innovative Technology Achieves NationalRecognition

Withglasses-free 3D visualization, the Radiation Oncology team at Hualien Tzu ChiHospital has moved beyond the limitations of traditional 2D imaging. Clinicaldecision-making is no longer dependent on mental reconstruction, but groundedin direct spatial perception of tumors, organs at risk, and dose distributions.

This shiftnot only improves efficiency and consistency, but fundamentally changes howclinical teams interpret and communicate spatial information—reducing cognitive burden and enabling more aligned, confidentdecision-making across disciplines.
