We present a compact and portable rotational laser profilometer which accurately measures the volume and color of wounds. In medicine, there is a need to measure wound-dimensions as predictive factors of venous-leg-ulcer healing. Using the existing, although inaccurate, methods, the length, width and depth can be measured. These measurements can be later used to determine the surface area and volume of the wound. The results of the analysis performed on the measurements of in-vivo wounds indicate that the repeatability is mostly dependent on the determination of the virtual healthy skin. Therefore, the algorithm for the determination of the area of virtual healthy skin bases on the previously found wound edge. Using this novel approach the relative error of the calculated volume was reduced under required 10%.

COBISS.SI-ID: 12075291A method for three-dimensional body shape monitoring during breathing in real-time is presented. It is based on the laser multiple-line triangulation principle, where the laser projector illuminates the measured surface with 33 equally spaced light planes. The distorted light pattern is recorded with a camera positioned at an angle towards the measured surface. The surface displacements are displayed with a color palette, which enables the patient to correct respiratory irregularities during the breathing exercises. The system is contactless and operates in high-speed (25 measurements/second) with the measuring range of approximately 400×600×500mm in width, height and depth respectively. The accuracy of the calibrated apparatus is ±0.7mm. The system can distinguish between different breathing patterns by means of determining the BPI (breathing pattern indicator). The accuracy of the measured volumes of chest wall deformation during breathing was verified with two standard methods of volume measurements. The results of the study show that the 3D measuring system with real-time respiration monitoring has great potential as a diagnostic and training assistance tool when monitoring the breathing pattern and evaluating the BPI, because it offers a simple on-screen graphical communication with the patient.

COBISS.SI-ID: 12075547Aesthetically pleasing and symmetrical breasts are the goal of reconstructive breast surgery. Sometimes, however, multiple procedures are needed to improve a reconstructed breast's symmetry and appearance. In order to avoid additional corrective procedures, we have developed a new method that uses a reverse engineering technique to produce what we call a new breast replica cast (NBRC). The NBRC is a mould of the contralateral healthy breast, designed according to preoperative laser 3D images. During surgery, the mould is used to help shape the new breast. With this method, we are able to achieve breast symmetry in terms of volume, projection, contour, and position on the chest wall more accurately, more quickly, and more safely than before.
