It deploys 2 ranging lights that converge on the target object when the camera is held at the optimum distance of 450вЂ“500 mm. It uses a Canon Rebel T6i camera body and is battery-operated. The Vectra H1 is a passive 3D digital stereophotogrammetry scanner.

This enables the software to compensate for any motion during the capture and provides a reference pattern for merging multiple captures. The field of view is 210 mmГ—300 mm, and the operating range is 350вЂ“450 mm.Д«oth the experimental and reference device (Vectra H1) are pre-calibrated by their manufacturers however, Scanify requires an optical tracking target to be positioned close to the object. The data acquisition speed is 0.1 seconds per scan, followed by a flash cool-down period of 15 seconds. The images are then processed to reconstruct a 3D image. Three xenon flash lights are triggered sequentially within milliseconds, illuminating the object at different angles and thereby allowing the cameras to capture 3 images of different shadows generated on the object surface. In this device, two 3.5-megapixel RGB cameras are positioned at an obtuse angle to each other. The experimental device, Scanify (Fuel 3D Technologies, Chinnor, UK). Our null hypotheses were that there would be no significant differences when comparing linear measurements between facial landmarks on scans of facial casts acquired with Scanify and Vectra H1, and that there would be no significant overall surface deviations when comparing 3D surface models generated from scans of facial casts acquired with Scanify and Vectra H1. The aim of this study was to validate the Scanify device for 3D imaging of facial casts. However, there is a lack of evidence in the scientific literature on the level of accuracy and precision that can be achieved with such a low-cost device, and whether the obtained images could meet clinical requirements. This scanner was available commercially for ВЈ950 until July 2017.

The advantages of a portable system are ease of use in any clinical setting with the subject in any position, easy transfer and storage, and minimal training requirements.ДЄnother portable scanner, Scanify (Fuel 3D Technologies, Chinnor, UK) was launched in 2015 as an ultra-lowcost, handheld optical scanner based on 3D stereophotogrammetry, suitable for 3D capturing of the face.

More recently, portable, single-camera stereophotogrammetry devices have become available, such as the Vectra H1 (Canfield Scientific, Parsippany, NJ, USA), which has been previously validated 3 and is marketed in the region of ВЈ13,000. These comprise multiple camera and flash units that require careful setup, calibration, and dedicated floor space, and range in price from approximately ВЈ25,000 to ВЈ35,500. Various 3D digital stereophotogrammetry systems are available, such as Canfield (Canfield Scientific, Parsippany, NJ, USA), 3dMD (3dMD, London, UK) and Di3D (Dimensional Imaging, Glasgow, Scotland, UK). Because it is also safe and reproducible, 5 it can be used for repeated measurements. 6 Other advantages include high-quality surface data and texture information, as well as the ability to image the face in the anatomic head position.

1, 5 Therefore, it is important to have accurate and reliable methods of recording external facial data.ДЄ widely-used technique for optical facial imaging is 3D digital stereophotogrammetry due to its ease of use and fast data acquisition time. Soft tissue landmarks are considered less reproducible than hard tissue landmarks on 2D cephalometric images 5 however, good soft tissue outcomes are a major goal of orthodontic and maxillofacial treatment, and are especially likely to determine patient satisfaction.

Optical imaging techniques (such as digital stereophotogrammetry, laser scanning, and structured light pattern methods) use visible light, and therefore are indicated for routine or repeated facial imaging, but only capture external structures. 4 Thus, they are not appropriate for long-term follow-up of patients or when multiple images are required. Additionally, the patient must be supine for CT and MRI scans, potentially distorting the soft tissues.

Whilst these techniques can capture internal and external anatomy, they incur very high costs and require qualified staff to operate, and CT and CBCT involve exposure to ionising radiation. Volumetric techniques include computed tomography (CT), cone-beam CT (CBCT), and magnetic resonance imaging (MRI). The current options for 3D facial imaging are either volumetric or surface imaging methods. 1 Its main applications include monitoring growth and soft tissue changes, surgical treatment planning (mostly in maxillofacial and orthognathic surgery), assessment of post-operative results, and construction of facial prostheses. Three-dimensional (3D) facial imaging is valuable for capturing the facial topography in contexts where conventional 2-dimensional (2D) photography conveys limited information.
