The Problem

Within the field of radiation oncology, the use of conventional bolus is seen as the weak link.  This flat piece of rubber-like material is placed on top of the patient’s skin and is used to increase the dose distribution to the skin, however, this conventional treatment method is unable to accommodate or correct for anatomical irregularities making it less than optimal.


Decrease in Efficiency

Conventional bolus is unable to accommodate anatomical irregularities, which results in air gaps that can cause underdosage to the patient’s surface.

Poor Patient Experience

Patients are required to be positioned for extended periods of time as radiation therapists manually construct bolus designs

Clinical Issues

Due to extended setup periods, clinics are unable to treat a high number of patients.

Introducing 3D Bolus

3D Bolus is a software application that provides practitioners with turn-key software that enables printing of patient-specific uniform thickness bolus, Modulated Bolus for MERT (modulated electron radiation therapy), High Dose Rate (HDR) surface brachytherapy and other potential ancillary devices.

  • All products are derived directly from the CT planning images.
  • 3D Bolus software fully integrates with existing treatment planning systems allowing the planning software to calculate the treatment plan with the 3D Bolus design.
  • All 3D Bolus products are designed and tested with full involvement by end users in the field.

3D Bolus Software has received a CE Mark and is ISO 13485 certified. It has been deployed in Cancer centers throughout the world. The company is currently applying for an FDA 510k and is an investigational device currently limited by Federal law to investigational use in the USA.


By applying innovative technology to a traditional industry, 3D Bolus is able to deliver a number of solutions.

1. Treatment Improvement

Smart algorithms allow modulation of bolus, achieving dose conformity to the PTV while sparing healthy tissues during treatment.

2. lower costs

3D Bolus eliminates the need for time consuming and cost intensive manual fabrication methods.

3. higher quality care

With increased efficiency and accuracy, 3D Bolus provides higher quality patient care.

4. decreased wait times

By reducing setup periods, clinics are able to treat a higher number of patients.


Compared to traditional accessories, 3D printed devices improve fit to the patient. This eliminates manual manipulation of traditional bolus which shortens setup time at every treatment fraction.


3D bolus recognizes that every patient is unique, and our solutions provide patient-specific solutions for every treatment.

our Products

3D Bolus delivers a number of software solutions that address the key issues associated with conventional treatment methods. 

Simple Bolus

 Bolus offers a custom fit, uniform thickness solution that is generated directly from patient CT data and can be 3D printed inhouse. This bolus conforms to simple or highly complex surface geometries which reduces air gaps and resultant surface dose uncertainty. The module also post-processing editing tools that ensure patient fit and comfort.

Modulated Electron Bolus

Modulated Electron Bolus enables users to create patient-specific bolus structures that tailor the prescription isodose to the prescribed tumor volume. Ray-tracing algorithms calculate a custom bolus design that changes the surface shape of the structure to allow for tailoring of the dose distribution while sparring of healthy tissues during treatment.

HDR Surface Brachytherapy

HDR Surface Brachytherapy enables user to create custom applicators that follow the surface contours of the patient.  Users have the ability to customize potential catheter positions that are embedded within the applicator. Once satisfied with the design, the module performs a subraction  to create hollow trajectories that allow for the insertion of afterloading catheters.
