“…The algorithms were verified in detailed high-resolution meshes captured via RoScan, a robotic 3D scanner able to provide 3D models having a resolution better than 0.1 mm [ 8 , 26 , 27 ]. The thermal images were taken using a LWIR thermal camera Xenics GOBI1954 with the resolution of 384 × 288 pixels, pixel pitch of 25 μ m, and spectral response in the wavelength range of 8–14 μ m. To establish a computational unit, we employed a desktop computer having an Intel Core i7-4790K processor at 4.00 GHz; 32 GB RAM; and an NVIDIA GeForce GTX 970 GPU.…”

Objectives At present, medical thermal imaging is still considered a mere qualitative tool enabling us to distinguish between but lacking the ability to quantify the physiological and nonphysiological states of the body. Such a capability would, however, facilitate solving the problem of medical quantification, whose presence currently manifests itself within the entire healthcare system. Methods A generally applicable method to enhance captured 3D spatial data carrying temperature-related information is presented; in this context, all equations required for other data fusions are derived. The method can be utilized for high-density point clouds or detailed meshes at a high resolution but is conveniently usable in large objects with sparse points. Results The benefits of the approach are experimentally demonstrated on 3D thermal scans of injured subjects. We obtained diagnostic information inaccessible via traditional methods. Conclusion Using a 3D model and thermal image data fusion allows the quantification of inflammation, facilitating more precise injury and illness diagnostics or monitoring. The technique offers a wide application potential in medicine and multiple technological domains, including electrical and mechanical engineering.

The digital medical thermal imaging is valuable qualitative tool for detection of inflamed or necrotic areas, but it lacks the ability of quantification. The new 3D scanning system RoScan composed from robotic manipulator, laser scanner, color camera and thermal imager is presented, extending medical thermal imaging with possibility of quantification, allowing specific ROI selection and bringing higher thermal resolution in resulting outputs. It helps to solve the current problem of medical quantification, which permeates through the many medical sectors. The advantages of RoScan are demonstrated on sample experiment, which shows the benefits of proposed device.

“…NEW VOLUMETRIC METHOD Contrary to Frustum Sign Model, Disc Model, Water Displacement Method and Optoelectronic Volumeters, what are the single-purpose methods or devices, this method applies multi-purpose Robotic 3D Scanner [44] in order to measure volume. Likewise the MRI or CT, it is not a device developed to measure volumes only, it is a universal 3D scanning device applicable for many other various purposes.…”

Abstract-This paper deals with application of 3D scanning technology in medicine. Important properties of 3D scanners are discussed with emphasize on medical applications. Construction of medical 3D scanner according to these specifications is described and practical application of its use in medical volumetry is presented. Besides volumetry, such 3D scanner is usable for many other purposes, like monitoring of recovery process, ergonomic splint manufacturing or inflammation detection.3D scanning introduces novel volumetric method, which is compared with standard methods. The new method is more accurate compared to present ones. Principles of this method are discussed in paper and its accuracy is evaluated and experimentally verified.
