Title: Method for determining a joint disk position of a temporomandibular joint by the mr image
Inventor: Bejnarovich Stanislav Viktorovich
IPC: A61B5/055

Granted: 2019-12-12
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to dentistry and radiodiagnosis, and can be used for determining the joint disk position of a temporomandibular joint by MR image. MR tomography of the temporomandibular joint (TMJ) in a sagittal plane in a position of the closed mouth and an open mouth is carried out with measurement of a corner expressed in degrees. Position of an intermediate portion of the joint disk, an angle relative to the joint fossa of the joint is determined on the MR image of the TMJ in the position of the closed mouth. For this purpose, as shown in figure 2, on MR image of TMJ, vertex of joint tubercle A and vertex of posterior joint process B are connected by conditional line AB. Perpendicular CD to AB line is drawn from deepest point of arched ostrum of joint fossa C. Point of intersection of these lines D is the vertex of the angle BDE. One ray of this angle passes along a segment of the BD connecting the vertex of the angle D with the vertex of the posterior joint process B. Second angle beam connects its vertex D with the intermediate zone E of the joint disk. In position of closed mouth at value of angle from 60° up to 120° position of the joint disk is physiological, while increasing the angle value greater than 120° front displacement of joint disk is determined, while angle value is less than 60° posterior displacement of joint disk. If the joint disk is displaced, if the position of the open mouth is physiological, then the displacement of the disc with correction is determined. If the position of the joint disk does not change in the open mouth position, the disc is displaced without correction. 
     EFFECT: method provides fast and accurate determination of the joint disk position of a TMJ relative to a joint fossa, which remains constant in the patient and which can be considered a permanent reference point.

Granted: 2019-12-04
Abstract: FIELD: technological processes. 
     SUBSTANCE: invention relates to solid-propellant charges in a downhole gas generator used in integrated treatment of wells as part of pulsed frameless devices to increase hydrocarbon output. Charge consists of a set of single-type sections made of ballistic fuel with a seven-slot central channel, on the side surface of which there are seven longitudinal grooves equidistant from each other along the circumference, offset relative to slits by 25°43', providing increased side surface of combustion and non-sufficient combustion of charge. Ignition of the charge is performed by an igniter installed in the zone of the most developed surface of the charge section – in the channel, at the top of the slot. Calculated number of charge sections is successively installed by means of coupling-centralisers on a steel rod passed through the channel of sections with application of connecting coupling-centralisers and lowered to the perforation zone of the casing string at the geophysical cable. Ignition charge is produced from on-board panel. Combustion takes place over entire surface of charge. When excessive pressure in the combustion zone exceeds the mine pressure, the matrix of the reservoir bed is reduced to form a fracturing area. 
     EFFECT: technical result consists in improvement of efficiency of charge.

Abstract: FIELD: radar ranging and radio navigation. 
     SUBSTANCE: invention relates to radar location of ocean surface from aircraft and can be used for search and detection of underwater hydrodynamic sources. Proposed method is based on transfer to the sea surface of an impulse generated by internal waves arising in the "density jump" layer, and formation of a "high-speed portrait" of the surface in an interference side-view radar with synthetic aperture (IRSA). Method for identification of moving underwater source uses formation of high-speed image of sea surface in radar of lateral view with real or synthesized aperture. After-period sum-difference method of signal extraction, which is proportional to radial flow velocity, makes it possible to form a velocity-calibrated image with suppression of both amplitude variations of the signal and phase speckle noise on the site of a given size. Secondary processing of the obtained image allows separating the internal waves excited by the underwater source and close to harmonic fields of orbital velocity of wind waves. 
     EFFECT: on formed image of internal waves it is possible to determine location of underwater source.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to obstetrics and gynecology, and can be used for laser-induced treatment of endometrial atrophy. Chlorophyll-containing preparation accumulation in endometrium is monitored by photoluminescent spectral analysis at 668 nm. Chlorophyll-containing preparation is pre-selected: a photoluminescent spectrum of the chlorophyll-containing preparation is recorded at wavelength of 405 nm and its intensity is compared at point of 668 nm with similar intensity of the international analytical standard Chlorophyll. If these intensities differ from each other by more than 30 %, the chlorophyll-containing preparation is replaced and the next preparation is checked unless a preparation satisfying the above requirement is found. Prescribed chlorophyll-containing preparation is administered orally once a day in the morning on an empty stomach for 10–30 drops for 4–6 weeks. Accumulation of chlorophyll-containing preparation in endometrium is monitored by photoluminescent spectroscopy. Dihydroquercetine is administered orally following the instructions. That is followed by 3–6 sessions of intrauterine laser therapy using disposable sterile capsules with a cylindrical scatterer consisting of quartz microspheres, laser light at wave length 0.63 mcm and energy density 5–500 J/cm 2 . 
     EFFECT: method provides recovery of the structure and function of the uterine mucosa by activating the process of epithelial regeneration and endometrial stroma as a result of long-term synthesis of singlet oxygen in photochemical reactions directly in endometrial tissues.
