Figure 4. (a) Therapy player software screen, where a) is the stimuli time, b) is the total therapy time, c) is the file path, d) displays the numeric values of each sequence of the therapy, e) shows the current value, and f) shows the current lag angle for zenith and azimuth values; (b) USB mechanism for conversion, where a) USB-UART converter, and b) USB-Zigbee converter.-Design of a Novel Servo-motorized Laser Device for Visual Pathways Diseases Therapy
<p>Where tt time expended by the servomotors to point the laser to a given position and execute<br> a laser beam sequence; tspin is the time that a servomotor needs to spin one degree; ttol is a given the<br> tolerance time; θservo is the addition of degrees that both servos in a laser driver need to spin point<br> the laser in a given position; tstimuli is the time expended in execute a laser beam, between 250 and<br> 605 ms (Weiskrantz et al., 1991); T is the total time of all repetitions in a therapy, suggested<br> between 20 and 60 minutes and N is the number of repetitions in a therapy.</p>
Figure 3. (Top): Illustration of the therapy selection main menu. This enables the user to select one of three options for the therapy. Stimuli sequence selectors; (Bottom): (a) Short distance – complete visual field; (b) Short distance – macular; (c) Middle-long distance.-Design of a Novel Servo-motorized Laser Device for Visual Pathways Diseases Therapy
<p>distance therapies for the prescribed time suggested by the ophthalmologist.<br> Note that the complete visual field therapy stimulates different parts in the entire visual field<br> whereas macular therapy stimulate only a small part of the visual field, only the first 10° of vision<br> range. In contrast, middle-long distance therapies are not developed inside the device; instead the<br> patient must sit watching a wall, where the stimuli will be presented. Figure 3 (Bottom) shows the<br> sequence selectors for the three different cases. The therapist will choose a desired number of<br> sequences according to the results of the examination to each patient; hence it is completely patient<br> dependent.<br> Once the therapist finishes the particular design of the stimuli sequence, the software<br> automatically displays a window where he can save the customized patient-specific details for future<br> use as a text file.</p>
Figure 2. (a) Representation of laser servo-driver for inverse kinematics analysis; (b) Representation of the lag angle, B, of the internal servomechanism (magnified version of the chin-rest).-Design of a Novel Servo-motorized Laser Device for Visual Pathways Diseases Therapy
<p>As the servo-driver will be attached in the chin-rest in a non-central area with respect to the<br> semispherical structure shown in Figure 1(a), it is necessary to calculate a lag angle, according to<br> the measurements from the chin-rest, see Figure 2(b). This was done using a hybrid formula based<br> on the law of cosines,</p>
Figure 1. (a) Part of the acrylic structure where the patient is enclosed to avoid external stimulus; (b) Chin rest, corresponding proportions and measurements.-Design of a Novel Servo-motorized Laser Device for Visual Pathways Diseases Therapy
<p>The device consists mainly of an acrylic semi-spherical structure (Figure 1(a)) where visual<br> stimuli will be shown, according to a pre-designed therapy. Four servomotors will drive the lasers,<br> two inside the structure (short distances drive the lasers, two inside the structure (short distance<br> therapies) and two outside (middle-long distance therapies). A chin-rest must be used to have a<br> better line of sight fixation. A webcam with infrared light will catch the Purkinje-Sanson images to<br> identify the sight line (Borah, 2006; Halswanter, 2011; Pambakian et al., 2000). LabVIEW software<br> is used to control the device, including an audio stimulus along with an image-processing pipeline.<br> Finally a microcontroller is used to control the servo movements, laser beams and buzzers.</p>
Laser Beam Characterization Data Related to Testing Different Near-Infrared Laser Therapy Devices Used in Sports Medicine
<p>This dataset contains laser beam characterization data collected for different near-infrared laser therapy devices that are used in sports medicine. Data were collected between September 2021 and December 2022 at the Department of Anatomy II (Neuroanatomy) of the Ludwig-Maximilians University of Munich, Germany. Laser therapy devices were characterized using a thermal power sensor, a photodiode, and a beam profiling camera (for details, see [1]). Two different laser therapy devices were investigated (Dolorclast High Power Laser, Electro Medical Systems; Cube 4 Med, Eltech K-laser s.r.l.). The measurements were repeated for three units of each laser therapy device (EMS-1, EMS-2, EMS3; K-1, K-2, K-3). The dataset contains raw data files from each sensor that include text (TXT) files, comma-separated-values (CSV) formatted files, and raw camera recordings in binary format (BINARY.BGDATA). The data was used to create figures that were submitted to the journal MDPI Biomedicines [1]. The figures in [1] were created with Python in a Jupyter Notebook, which is also included in this dataset.</p> <p><strong>2023-02-17 Update: The manuscirpt has been published in MDPI Biomedicines [2].
