Robotic 3D scanner as an alternative to standard modalities of medical imaging

Abstract

There are special medical cases, where standard medical imaging modalities are able to offer sufficient results, but not in the optimal way. It means, that desired results are produced with unnecessarily high expenses, with redundant informations or with needless demands on patient. This paper deals with one special case, where information useful for examination is the body surface only, inner sight into the body is needless. New specialized medical imaging device is developed for this situation.In the Introduction section, analysis of presently used medical imaging modalities is presented, which declares, that no available imaging device is best fitting for mentioned purposes. In the next section, development of the new specialized medical imaging device is presented, and its principles and functions are described. Then, the parameters of new device are compared with present ones. It brings significant advantages comparing to present imaging systems.

Three-dimensional Thermal Imaging in Medicine

“…1). The robot used in this device is EPSON C3, which is reaching excellent accuracy of end-point placement ±0.013 mm [9] and the laser scanner is also very accurate MicroEpsilon ScanCONTROL2750-100 with accuracy ±0.027 mm [10], what provides overall accuracy 1 of entire 3D surface scanning system of ±0.12 mm [11].…”

A Magnetic Laser Scanner for Endoscopic Microsurgery

“…welding of blood vessels, and laser surgery [3]. For medical imaging, laser scanners have even been proposed as an inexpensive alternative to the standard imaging systems such as computed tomography (CT) and magnetic resonance imaging (MRI) [4].…”

Application of High-Resolution 3D Scanning in Medical Volumetry

“…The big advantage is the possibility of selection of region of interest. There are several parameters available to be measured: [44] or [8].…”

“…As long as the Robotic 3D Scanner is properly calibrated, the only considerable sources influencing scanner's accuracy are robotic manipulator accuracy (∆ M ) and laser scanner accuracy (∆ S ). Relation between these symbols has been derived in [8] as follows 6 :…”

“…Another objects are visible, but its important details are too tiny (human outer structures) and it is necessary to enlarge them plastically [8].…”
