Using an overview skenogram with a length of 150-700 mm, multi-planar reconstructions of the image are constructed in two mutually perpendicular planes - the frontal and sagittal. The images reveal the localization, volume and nature of the internal structure of the child's spine. The resulting tomographic information is stored in DICOM format and transferred to Dolphin Imaging. The formation of a solid-state STL 3D model of the spine is performed with the display of all affected bone anatomical structures and spinal anomalies of interest in the preoperative study. According to the STL model data, a G-code is formed. A model of the patient's spine with all its anomalies is printed with a print layer height of no more than 0.2 mm on a scale of 1:1 on an FDM printer. The model of the spine is made of a biologically compatible and non-toxic polymer material. As a biologically compatible and non-toxic polymer material, acrylonitrile butadiene styrene (ABS), or polyethylene terephthalate with glycol (PET-G), or polylactide (PLA), or polyamide are used for the manufacture of the model of the spine. Virtual planning of the stages of surgical treatment of the patient's spine is performed using a manufactured model of the spine or part of it with the determination of the placement points of implants and the malposition of the fixing screws of metal fixation during corrective osteotomy.

Previously, before launching, client computers with built-in software are installed in the group of rowing vessels along their central longitudinal axis, wherein training parameters are downloaded to the client computer before training begins and are controlled automatically or manually. Then, client computers are combined into a local network using a coach computer with server software, additionally equipped with an information display device. At the same time, an athlete is equipped with a chest module that includes a group of sensors with wired and wireless connections and a voice detector. After that, the client computer is started. Then, the coach assigns conditions of training load parameters individually to each rower. Next, the training in the water area is carried out in three stages, including a warm-up, a main part and a cool down. Then, the main part is divided into several segments, on each of which the athlete performs a training session with the specified parameters of the training load. In the monitoring mode, groups of athletes transmit and collect the received data of training load parameters to the system server, memory accumulation and information processing of individual athletes during training. The registration of parameters of the training load is carried out with a discreteness of 5-10 s. At the same time, the server of the coach computer provides visual information to a screen of the information display device. After that, the coach, from his workplace, selects a vessel of the controlled athlete during a race. At each segment of the distance in real time, the coach conducts visual monitoring of his position in the water area and parameters of the training load: speed, pace, distance traveled and physiological parameters of the athlete, corrects them with the help of voice detector messages generated by his commands, and if critical physiological parameters of the rower are exceeded, the detector is triggered automatically or manually by the coach decision.  
     EFFECT: technical result is obtaining the method for operational correction of parameters of training loads of athletes-rowers.

Abstract: FIELD: physics.SUBSTANCE: invention relates to television methods of obtaining an image. Result is achieved by the fact that the lens forms an image on an area equal to the sum of light-sensitive areas of n CCD matrices. CCD matrices are shifted relative to each other. This image is projected on all CCD matrices on four channels so that each of them generates a video signal from only one of n sectors of this image. Video signals from CCD matrices, which operate in parallel, are digitized, pre-processed and recorded into memory, from where they are read at a frequency n times higher than the clock frequency. Digital image is obtained by electronic combination of video signals of CCD matrices, which convert adjacent sectors of the image, after which the video signal is finally processed. Method is realized with the help of a device comprising an optical unit, n converters of an optical image into a digital signal, a control unit, a commutator and a final processing unit.EFFECT: high quality of a digital image by increasing its resolution by n times.2 cl, 5 dwg
