“…Placing the 3D printed bolus in the treatment area placed the target position at an acceptable level and the air gap between the patient's body and the bolus was less than 5 mm. Most of the desired area was covered by a 3D printed blouse with a 95% uniform dose [15,[17][18][19][20][21].…”

Nowadays, three-dimensional (3D) printing technology has been used for rapid prototyping of high quality printed objects. This technology has taken a special place in the field of medicine, and today this technology plays an important role, especially in the field of radiotherapy. Radiotherapy is a main option for treating and management of various types of cancers. Personalized radiotherapy requires precise details. For this reason, it is very important to carry out the exact treatment design at the clinical. 3D printing technology is considered a promising method that can be effective in the treatment of each person in a specific way and as a complementary and promising method to help in integrated treatment and special equipment for each patient. In this chapter, various applications of this technology in radiation therapy have been discussed. This narrative review summarizes the applications of 3D printing technology to develop patient-specific bolus, brachytherapy applicators, phantoms, filters, immobilization and grid therapy devices for more personalized radiation treatment.

“…There is an increasing number of studies to demonstrate various applications of AM technology 4 and its significant utility in manufacturing radiotherapy devices, not only for imaging and dosimetry phantoms but also for bolus, [5][6][7][8] immobilization tools, [9][10][11][12] , brachytherapy moulds, [13][14][15][16][17] electron beam cutouts, [18][19][20][21] and compensator devices. [22][23][24] Other medical applications for AM also include pharmaceutical 25 and surgical applications. 26,27 Within the last decade, a number of studies have investigated the use of AM technologies to produce customized patient-specific RPs using different types of in-house and commercially available AM materials including thermoplastics and photopolymer resins.…”

Introduction: Additive manufacturing or 3-dimensional printing has become a widespread technology with many applications in medicine. We have conducted a systematic review of its application in radiation oncology with a particular emphasis on the creation of phantoms for image quality assessment and radiation dosimetry. Traditionally used phantoms for quality assurance in radiotherapy are often constraint by simplified geometry and homogenous nature to perform imaging analysis or pretreatment dosimetric verification. Such phantoms are limited due to their ability in only representing the average human body, not only in proportion and radiation properties but also do not accommodate pathological features. These limiting factors restrict the patient-specific quality assurance process to verify image-guided positioning accuracy and/or dose accuracy in “water-like” condition. Methods and Results: English speaking manuscripts published since 2008 were searched in 5 databases (Google Scholar, Scopus, PubMed, IEEE Xplore, and Web of Science). A significant increase in publications over the 10 years was observed with imaging and dosimetry phantoms about the same total number (52 vs 50). Key features of additive manufacturing are the customization with creation of realistic pathology as well as the ability to vary density and as such contrast. Commonly used printing materials, such as polylactic acid, acrylonitrile butadiene styrene, high-impact polystyrene and many more, are utilized to achieve a wide range of achievable X-ray attenuation values from −1000 HU to 500 HU and higher. Not surprisingly, multimaterial printing using the polymer jetting technology is emerging as an important printing process with its ability to create heterogeneous phantoms for dosimetry in radiotherapy. Conclusion: Given the flexibility and increasing availability and low cost of additive manufacturing, it can be expected that its applications for radiation medicine will continue to increase.

Investigation purpose. Theoretical study of the depth dose measurements for therapeutic electron beam with longitudinally arranged dosimetry films in materials with different densities. Materials and methods. The work studies how the density of the medium, in which electrons propagate, affects the measured percentage depth dose and its reliability (PDD). For that, we calculate the distribution of the electron beam dose distribution in homogeneous materials with different densities and in a dosimetry film placed in materials with these densities. The density of material in the calculation varies from 0.4 to 2.3 g/cm 3 with a 0.1 g/cm 3 step. The coincidence of the PDD within the experimental measurement accuracy, that equals 4% for dosimetry film and 2% for measurements without it, is chosen as the data fitting criterion. Results. The PDD calculated for two geometries and for different media densities is the result of this work. The calculation shows that PDD difference is negligible when the density of the film is equal to the media one. With decreasing of the media density the difference appears in the regions of both shallow and great depth. The PDD is lower for the geometry with film than for geometry without it in case of these densities. When the media density is rising the opposite effect is observed: the PDD in the film is higher than in geometry without film. The maximum range and therapeutic range in both geometries coincide for the calculated curves throughout the range under study. Discussion. The work shows applicability of the investigated method for measurement of the electron beam percentage depth dose in media 1Corresponding author.
