Lumora promises workflow efficiency with pliable and drapeable custom bolus
Bolus is one of the most widely used tools in external beam radiotherapy, yet it remains one of the most operationally challenging, says medical equipment manufacturer CDR Systems.
As radiotherapy advances towards greater precision, tighter margins and adaptive techniques, expectations for surface dose accuracy and reproducibility have increased. However, many clinics rely on flat sheets that are manually cut, layered, taped and repositioned across fractions.
“These familiar workarounds introduce variability that can undermine both efficiency and confidence in dose delivery,” the company says. “Traditional sheet bolus materials are inherently flat, while patient anatomy is not. This mismatch commonly results in air gaps, particularly over irregular contours or post-operative sites. Such air gaps are well documented to reduce surface dose and introduce uncertainty between planned and delivered dose.”
While rigid 3D-printed bolus can improve conformity and reproducibility, it introduces its own challenges, including additional planning steps, production lead times, limited adaptability to daily anatomical variation and increased resource demands.
Point-of-care solutions, such as Lumora Custom Bolus, are custom-formed directly to the patient within the clinical workflow, without the need for 3D printing, outsourcing or extended preparation time.
“This model offers clear advantages from an operational standpoint: immediate availability, reduced set-up complexity and improved consistency across treatment fractions,” CDR states. “Lumora retains a patient-specific shape while remaining pliable and drapeable. This allows intimate surface contact to be maintained across fractions while accommodating minor changes in patient positioning or anatomy, supporting both reproducibility and clinical realism.”
