Evaluation of optical 3D scanning system for radiotherapy use

Abstract

Introduction Optical three‐dimensional scanning devices can produce geometrically accurate, high‐resolution models of patients suitable for clinical use. This article describes the use of a metrology‐grade structured light scanner for the design and production of radiotherapy medical devices and synthetic water‐equivalent computer tomography images. Methods Following commissioning of the device by scanning objects of known properties, 173 scans were performed on 26 volunteers, with observations of subjects and operators collected. Results The fit of devices produced using these scans was assessed, and a workflow for the design of complex devices using a treatment planning system was identified. Conclusions Recommendations are provided on the use of the device within a radiation oncology department.

A Comparative Study between Scanning Devices for 3D Printing of Personalized Ostomy Patches

“…The weight of the Artec Leo scanner (2.6 kg) represented discomfort for the operators in the longer sessions, similarly to Go!scan 20, unlike the Structure Sensor. Furthermore, Crowe S et al [18] and Shah PB et al [21] mentioned difficulties to scan data in shadowed regions (e.g., areas behind the ear), which also happened in the present study in zones hidden by stomach fat using Go!scan20. The Structure Sensor did not have any problems with these zones.…”

“…Crowe S et al [18] mention the advantage of wireless connection and no required previous training using Artec Leo scanner as well as the Structure Sensor in our study. Furthermore, they highlighted the feedback advantages of the screen for the operator, like our study with the Go!scan 20 scanner.…”

“…The medical field requires geometrically accurate and high-resolution medical images for a precise measurement and diagnosis [18]. Different studies have incorporated the use of 3D scanners in the medical field, being used mainly in face and head scanning [18][19][20][21][22][23]. Crowe S et al [18] used the Artec Leo structure light scanner for two purposes.…”

“…Regarding the limitations, different aspects were considered, such as the duration of the scanning sessions, device weight, high level of expertise using the scanners and difficulties to scan some areas of the body. Crowe S et al [18] took up to 50 min for the session scanning, more than our study that included two scanners and the removal of the first stoma patch and dressing the new one after completing the scanning. The weight of the Artec Leo scanner (2.6 kg) represented discomfort for the operators in the longer sessions, similarly to Go!scan 20, unlike the Structure Sensor.…”
