Using 3D anthropometric data for the modelling of customised head immobilisation masks

3D Printing of Abdominal Immobilization Masks for Therapeutics: Dosimetric, Mechanical and Financial Analysis

“…For example, for head and neck masks, a lower infill—and hence, more open area—could be used to minimize the feeling of patient claustrophobia, and for abdominal or pelvic masks, the infill could be higher since this effect may not be triggered. Loja et al [ 28 ] proposed an alternative head immobilization mask prototype. Second, the patient does not have to undergo the uncomfortable and time-consuming process of mask molding, since the proposed process is contact-free.…”

“…The present technology could also be implemented in nuclear medicine and imaging departments. For example, some PET head or abdomen acquisitions can take up to 30 min [ 7 , 28 , 29 , 30 ]. According to Mantlik et al [ 7 ], PET/MR imaging requires the use of devices to assist patient immobilization and positioning for the entire duration.…”

Establishment of open web platform based on 3D head model for product adaptability analysis and evaluation

“…On the other hand, Loja et al. [ 26 ] used CT imaging to obtain 3D anthropometric data and applied these to the modeling of a head-fixed thermoplastic mask for patients undergoing radiotherapy. The results showed that the improved fixed-mask structure based on anthropometric data provided patients with better health care, comfort, and lower facial pressure.…”

An Optimization Strategy for Customized Radiotherapy Head Immobilization Masks

“…The fixture of the mask to the radiotherapy table is provided via a U-shaped scheme horizontally fixed to the mask surface ( Figure 1). The strength, stiffness and material selection studies were already performed in [6], [7]. Presently this immobilization device will be optimized via a hybrid metaheuristic approach, in order to obtain an optimal configuration concerning to its stiffness.…”

“…From the literature review it is possible to conclude that the combination of acquisition and reconstruction techniques as well as the subsequent modelling can provide effectively advantageous purpose-oriented customized devices as presented in [3] - [6]. However, it may be concluded that an extensive work is still needed.…”
