Устройство для визуализации вен в инфракрасном диапазоне

Номер: RU0000209146U1

Автор: Рафаэл Вагифович Магеррамов

Принадлежит: Общество с ограниченной ответственностью "МЭЙДЖИК ВЬЮ"

Настоящая полезная модель относится к медицинской технике и медицинскому оборудованию, а именно к неинвазивному портативному устройству для визуализации подкожных вен с использованием источников света в инфракрасном (ИК) диапазоне и ИК-камеры. Предлагаемое устройство может быть использовано для неинвазивной визуализации периферийных подкожных вен при проведении таких венозных манипуляций, как: введение внутривенных инъекций, забор крови из вены, установка внутривенных катетеров, проведение склеротерапии, проведение диагностики и исследования сосудов и сосудистых нарушений. За счет использования длин волн ближнего ИК-диапазона происходит контрастная визуализация вен, так как свет с длиной волны более 700 нм проникает глубже в кожу. При этом ближний ИК-свет минимально поглощается меланином (высокомолекулярный пигмент кожи), но сильно поглощается кровью в венах. Это позволяет дифференцировать кровеносные сосуды и окружающие ткани. В частности, ближний ИК-свет, попадающий на участок тела человека, поглощается кровеносными сосудами. Чем больше ближний ИК-свет поглощается, тем меньше происходит его отражение, которое фиксирует ИК-камера. Чем меньше поглощают ближний ИК-свет окружающие ткани, тем больше они его отражают. Поэтому, изображение вен, полученное ИК-камерой, имеет темную контрастную структуру, а окружающие ткани имеют более светлый оттенок. Сущность полезной модели заключается в том, что устройство для визуализации вен в инфракрасном диапазоне, состоящее из принимающего устройства, корпуса, инфракрасной камеры с инфракрасными светодиодами и датчиком освещенности, соединенных между собой первой печатной платой, микроконтроллера, контроллера аккумуляторной батареи и драйвера инфракрасных светодиодов, соединенных между собой второй печатной платой, кнопки включения и аккумуляторной батареей, соединенных со второй печатной платой проводным соединением, передает изображение вен по беспроводному соединению Wi-Fi принимающему устройству (планшету, монитору, ...

System for correlating energy field characteristics with target particle characteristics in the application of the energy field to a living organism for detection of invasive agents

Номер: US20120190978A1

Автор: Daniel B. McKenna, Karl M. Frantz

Принадлежит: Actium Biosystems LLC

The Energy Field and Target Correlation System automatically correlates the characteristics of target particles and a living organism to compute the characteristics of an energy field that is applied to a living organism to activate the target particles which are bound to or consumed or taken up by invasive agents in the living organism to produce detectable effects which can be used to diagnose the presence and locus of the invasive agents. The energy field must be crafted to properly control the response and localize the extent of the illumination. The System automatically selects a set of energy field characteristics, including: field type, frequency, field strength, duration, field modulation, repetition frequency, beam size, and focal point. The determined energy field characteristics then are used to activate field generators to generate the desired energy field. A multi-dimensional image is produced identifying the spatial extent of the invasive agent.

An aspiration chamber is provided with an aspiration aperture, having a shape in which a width becomes larger from one edge toward another edge, and aspirates soft tissue through the aspiration aperture. A deformation amount measurement portion measures aspiration deformation amounts of the soft tissue within the aspiration aperture along a virtual line from the one edge to another edge. Based on the aspiration deformation amounts that have been measured by the deformation amount measurement portion, a computer uses a finite element model of the soft tissue to derive an approximation equation according to a numerical function for the aspiration deformation amounts and positions on the virtual line and determines a distribution of elasticity from the surface of the soft tissue into its interior by substituting parameters of the approximation equation into estimation equations that are derived by assuming that the deformation along the virtual line reflects elasticity distribution parameters.

Принадлежит: Novadaq Technologies ULC

Vessel perfusion and myocardial blush are determined by analyzing fluorescence signals obtained in a static region-of-interest (ROI) in a collection of fluorescence images of myocardial tissue. The blush value is determined from the total intensity of the intensity values of image elements located within the smallest contiguous range of image intensity values containing a predefined fraction of a total measured image intensity of all image elements within the ROI. Vessel (arterial) peak intensity is determined from image elements located within the ROI that have the smallest contiguous range of highest measured image intensity values and contain a predefined fraction of a total measured image intensity of all image elements within the ROI. Cardiac function can be established by comparing the time differential between the time of peak intensity in a blood vessel and that in a region of neighboring myocardial tissue both pre and post procedure.

Functional imaging for localization in biological tissue entails measuring a response in the tissue () to electromagnetic radiation. A catheter () for real-time monitoring of cardiac ablation is employed to distinguish a hemorrhage zone () from the sandwiching necrotic and healthy tissue, or to distinguish exogenous photoacoustic contrast agent from bordering native tissue. A pair of wavelengths is selected for differential absorption () of the radiation in, correspondingly, the hemorrhage zone or where the contrast agent exists, and relatively similar absorption elsewhere. Near infrared laser or LED light may be used photoacoustically to serially acquire (S S) the two datasets to be compared, each representative of a time waveform. Alternatively, acquisition is for a pair of wavelength bands of microwave-induced thermoacoustic data. In either case, the members of the dataset pair are combined () by subtraction or division to effect the piece-wise cancellation/enhancement for display () of the resulting signal in real time. 1. An apparatus configured for using functional imaging for localization of biological tissue , said apparatus comprising:a processor for measuring responses in the biological tissue to electromagnetic radiation and distinguishing borders within the biological tissue of one or more of (i) a hemorrhage zone, disposed between (i)(a) healthy tissue and (i)(b) ablated tissue, from said healthy and ablated tissue, and (ii) a contrast agent from bordering native tissue, based upon the responses, wherein distinguishing the borders comprises combining, via the processor, datasets acquired, via a transducer, by electromagnetic irradiation, via an emitter, at different frequencies or frequency bands, wherein the datasets serve as measures of absorption by said biological tissue of the electromagnetic radiation, and wherein the different frequencies or frequency bands are (iii) selected for (iii)(a) differential absorption of radiation in, correspondingly, ...

Multispectral imaging for quantitative contrast of functional and structural features of layers inside optically dense media such as tissue

Номер: US20140092288A1

Автор: Brenda Hattery, David Hattery

Принадлежит: Individual

A method for evaluation of target media parameters using visible through near infrared light is disclosed. The apparatus comprises a light source, illuminator/collector, optional illumination wavelength selector, optional light gating processor, imager, detected wavelength selector, controller, analyzer and display unit. The apparatus illuminates an in situ target. The sample absorbs some light while a large fraction of the light is diffusely scattered within the sample and some light exits the sample and may be detected in an imaging fashion using wavelength selection and an optical imaging system. The method extends the dynamic range of the optical imager by extracting additional information from the detected light that is used to provide reconstructed contrast of smaller concentrations of chromophore. Using a reiterative calibration method, acquired spectra and images are analyzed and displayed in near real time in such a manner as to characterize functional and structural information of the target tissue
