Abstract
This papers presents a comparative study of three different 3D scanning modalities to acquire 3D meshes of stoma barrier rings from ostomized patients. Computerized Tomography and Structured light scanning methods were the digitization technologies studied in this research. Among the Structured Light systems, the Go!Scan 20 and the Structure Sensor were chosen as the handheld 3D scanners. Nineteen ostomized patients took part in this study, starting from the 3D scans acquisition until the printed ostomy patches validation. 3D mesh processing, mesh generation and 3D mesh comparison was carried out using commercial softwares. The results of the presented study show that the Structure Sensor, which is the low cost structured light 3D sensor, has a great potential for such applications. This study also discusses the benefits and reliability of low-cost structured light systems.
Highlights
Scanning Devices for 3D Printing of Colorectal cancer is one of the most frequent tumors and the second in terms of mortality worldwide, and the second most detected type of cancer in the Basque Country, with an 18% of the total amount [1]
The population included in this study is part of the INTELOST project aims at developing intelligent patches for ostomy meshes, customized to the anatomy of each patient through 3D printing and intelligent technology
The fundamental contribution of this study is that it has shown that it is possible to use low-cost scanners to obtain images of the abdominal surface without irradiating the patient, reducing the risks of new cancers due to radiation emitted by conventional methods. It would reduce the discomfort of patients with surgical procedures or treated for colorectal cancer who undergo numerous scanner evaluations throughout their follow-up, due to the recurrences of their original tumors
Summary
Scanning Devices for 3D Printing of Colorectal cancer is one of the most frequent tumors and the second in terms of mortality worldwide, and the second most detected type of cancer in the Basque Country, with an 18% of the total amount [1]. The most frequent complication is the change in the configuration of the abdominal perimeter of the patient after the surgery, generated by the variations in their weight and the practice of sports. Due to the natural intra-abdominal pressure, the orifice tends to increase in size giving rise to parastomal hernias [7,8]. All these alterations mean that on numerous occasions, the commercial ostomy patches, that cover the stoma, do not adapt adequately to the skin of the abdomen, and they detach causing significant problems for the patient
