In this present study, two popular bolus materials namely Gel Bolus and Wax bolus were validated radiologically; then, their dosimetric performance was compared with Virtual bolus found in the treatment planning system.

This study aimed to examine the volume, dimensional and dose differences between manually manufactured wax bolus and a 3D printed shell to the virtual bolus demonstrated in a radiotherapy plan for photon treatment to the nose, and to explore which …

A traditional solution to this problem is the paraffin wax box bolus. Such a bolus is made to fit the irregular surface compensating for the topology and creating an even surface. The fabrication of a wax bolus can be a difficult and time-consuming process.

Blue Wax Uniform Thickness Bolus. We offer a patient-specific radiation therapy bolus. A bolus is an important tool to bring dose towards the patient surface, but often a patient’s irregular anatomy makes it hard to eliminate air gaps using conventional flat sheet bolus materials.

In the present study, the dosimetric properties for bolus materials such as natural rubber, the mixture of silicone rubber with bismuth or aluminum, paraffin wax, red plasticine, and play-doh were evaluated.

Sep 1, 1996 · The fabrication of a wax bolus can be a difficult and time-consuming process. A method that is simple and efficient has been devised. Super Stuff ® bolus can be easily molded and has approximately the same effect as a similar paraffin wax bolus.

This study evaluates the volumetric, dosimetric and cost differences between traditional wax and 3D printed versions of nose bolus. Method: Nose plaster impressions from 24 volunteers were CT scanned and planned.

Dec 1, 2019 · Objectives: In the present study, first, radiological properties of superflab Gel bolus and Paraffin wax bolus was investigated in terms of their relative electron density. Then, dosimetric performance of both the bolus (i.e. Gel and …

Dec 4, 2019 · Objectives: In the present study, first, radiological properties of superflab Gel bolus and Paraffin wax bolus was investigated in terms of their relative electron density. Then, dosimetric...

The wax bolus used for treatment was contoured and concordance of the wax bolus and planned bolus contours was assessed using the Dice coefficient. A 3D printer was then used to create a 3D representation of the bolus directly from the TPS.
