In complex treatment cases that require modulated boluses, outdated methods were delivering low dosages to the target volume or compromising healthy tissues. Adaptiiv's modulated electron bolus enables cancer centers to produce boluses of varying thickness resulting in vastly improved dose distributions.
Our software can convert DICOM data taken from patient CT scans and turn them into a digital model which can be printed, no matter how large, small, or complex. There is no intensive training required to use our software enabled solution which fully integrates with existing treatment planning systems.
We provide the 3D printers and materials, or centers can even use their own. Centers never need to outsource patient data in order to create the devices. When the hardware is combined with our software, centers can care for patients entirely in-house and adapt to treatment changes quickly. Plus, our printers go through a rigorous QC process adapted for printing medical devices.
Our 3D boluses are created to conform perfectly to individual body shapes. Our recommended filaments go through a QC process unique to printing accessory medical devices. In addition, we take pride in printing our devices from recycled plastic. We also track inventory and restock materials so centers and patients worry about what's most important.
In the past, centers have needed to manually create modulated boluses to accommodate for the contours of the patient's anatomy or tumour volume which is time consuming and less accurate. This not only presents a challenge to the device's durability (in the case of wax moulds), but also makes it difficult to achieve an ideal dose distribution and protect healthy tissues.
To be able to target each patient's PTV, we needed a device that offered the durability of a Uniform Thickness Bolus, but with the ability to fluctuate in thickness that molding wax offered.
Our modulated electron bolus is printed in tissue-equivalent materials that offer superior durability, no matter the thickness or thinness required. Most patients often use the same bolus for the entirety of their treatment, reducing the risk of infection and lowering procedure cost. In addition, centers are able to care for patients immediately in-house and adapt to treatment changes quickly.
The time and difficulty it takes to create a conventional modulated electron bolus means very few centers have the necessary resources or experienced staff required.
Adaptiiv's all-in-one solution includes easy to use software and hardware. Once a staff member can create a Uniform Thickness Bolus, graduating to modulated electron boluses requires just a few extra software steps. The printing process is the same.
Conventional modulated boluses were never able to achieve optimum thickness or thinness in the correct areas, leading to sub-optimal treatment.
By importing each patient's treatment plan through our point and click software, the ray-tracing algorithms embedded within the module evaluate the distance between the PTV and prescription isodose line to create a bolus that provides optimal dosimetry.

Because conventional boluses were unable to achieve optimal PTV coverage, some areas below the bolus received higher than ideal dosage also known as "hot spots".
Because the modulated electron bolus is able to successfully conform to the PTV, the occurrence of hot spots has been reduced.
Modulated Electron Bolus
About our Modulated Electron Bolus module and how Adaptiiv's solution is dedicated to the personalization of healthcare by enabling the creation of medical devices which deliver more precise treatments while significantly improving patient outcomes and putting control back in the hands of the patients.
A leading North American Cancer Institute recently attempted to manually design their own 3D printed bolus that would be used to treat a delicate area on a patient's scalp. The leading therapist spent over 30 hours to create the bolus, manually drawing the correct bolus shape, calculating the prescribed dose distribution, adjusting the exterior contours, and re-calculating the dose, all to ensure the isodose was conformal to the PTV.
When the same patient information was fed into Adaptiiv's automated software, the therapist was amazed. "Adaptiiv's software took under 2 minutes to develop a complex bolus that took my team and I over 30 hours to plan, design, and execute."
A Canadian Cancer Center recently used the Adaptiiv's Modulated Electron Bolus in a particularly complex case where the treatment area was close enough to the patient's brain to cause concern about overexposure of healthy brain tissue.
"Adaptiiv's bolus fit very well and the dosimetry is excellent, especially with regard to 90% dose conformity. All are pleased – including myself, our radiation oncologists, and the therapists involved. A plan like this wouldn't be possible any other way."
