A device, system and method for measuring free gas in a cavity of a subject. The device, system and method include a light source for emitting light with a wavelength associated with an absorption band of the free gas, an optical fibre connected to the light source and adapted to be inserted using an introducing member for internal illumination, and a detector adapted to be positioned on a skin surface for detecting light transmitted through the tissue. The device, system and method further includes a control unit for evaluating the detected transmitted light for determining the free gas, or a distribution of the free gas, or concentration of the free gas.

System and method for laser based internal analysis of gases in a body of a human

A method and apparatus are disclosed for assessment of a sealed package. Light is emitted from a narrow-band laser source towards said package from outside of said package. An absorption signal of said light scattered in said package is measured, wherein said absorption is caused by said at least one gas when said light is scattered and travels in said sealed package. Measuring is made outside of said package, whereby said assessment is non-intrusive with regard to said package. It is determined if a deviation exists from a predetermined, expected gas composition and/or concentration of said at least one gas within said sealed package based on said measured absorption signal. Thus sealing of said package for said gas is detected.

Apparatus and method for non-intrusive assessment of gas in packages

A system and method for interactive therapy and diagnosis of a human or animal comprising at least one first radiation source for emission of a diagnostic radiation, at least one second radiation source for emission of a therapeutic radiation, and at least one radiation conductor adapted to conduct radiation to a tumor site at or in said human or animal. A non-mechanical operation mode selector directs the therapeutic radiation and/or the diagnostic radiation to the tumor site through the radiation conductors. The operation mode selector means is preferably a non-mechanical optical switch and/or an optical combiner. The system may be used for interactive interstitial photodynamic tumor therapy.

System and method for therapy and diagnosis comprising optical components for distribution of radiation

A method and system for controlling and adjusting light in interstitial photodynamic light therapy (IPDT) in a subject is disclosed. More particularly, a method for controlling the light in interstitial tumor photodynamic light therapy is described using a calculation method for determination of status of tissue during the PDT treatment. The status is used in a feedback loop to control the continued PDT treatment. Methods are disclosed that constitute pre-treatment and realtime dosimetry modules for IPDT on the whole prostate glandular tissue. The method includes reconstruction of the target geometry, optimization of source fiber positions within this geometry, monitoring of the light attenuation during the treatment procedure and updating individual fiber irradiation times to take into account any variation in tissue light transmission. A control device that is arranged to restrict delivery of therapeutic light treatment at least temporary in dependence of at least one attribute of one of photodynamic treatment parameters. In comparison to no treatment feedback, a significant undertreatment of the patient as well as damage to healthy organs at risk are avoided.

System and method for controlling and adjusting interstitial photodynamic light therapy parameters

A system for providing interstitial photodynamic and/or photothermal therapy on a region of tissue in a body, comprising at least one light source adapted to deliver a therapeutic light to the region of tissue, such that the light source is interstitially inserted into the tissue for interaction with a photosensitizer agent and/or for providing a controlled thermal environment of the tissue; and a unit for determining an optimized number of the light sources and individual position of each of the light sources in the region of tissue as well as individual control parameters for each of the light sources.

System and method for pre-treatment planning of photodynamic light therapy

A device and method for gas measurements in body cavities are provided. These may be any body cavity containing a free gas, where there is an interest in detecting and/or measuring the concentration of said free gas by non-invasive or minimally invasive method. According to an exemplary embodiment measurement of free oxygen in cranium cavities is performed by scattering media absorption spectroscopy, and in particular variations of such oxygen. This is particularly useful for diagnostic purposes based on the measurements, for instance for detecting sinusitis or the like.

Human cavity gas measurement device and method

A method and device for investigation of a surface layer of a material. The material without surface layer is exposed for a gas and the penetration of the gas into the material is measured. Then the surface layer is applied to the material. Finally, the material including the surface layer is exposed for the gas and the penetration of the gas into the material through the surface layer is measured. The measurement of the passage of the gas into the material is performed by a method comprising measurement of light absorption by the gas by absorption spectroscopy.

Method and device for investigation of a surface layer

A system and method for interactive interstitial photo-dynamic tumour therapy and/or photothermal tumour therapy of a human or animal, said system comprising at least one radiation distributor, which is arranged for distribution of optical radiation from at least one radiation source to a reaction site, or from the reaction site to at least one radiation sensor. The radiation distributor comprises at least one translatory displacement element being translatory movable relatively to another element. First ends of first radiation conductors are fixed to the first translatory displacement element and first ends of second radiation conductors are fixed to the other element, wherein the first and the second radiation conductors are connectable to each other in different constellations through translatory movement of the translatory displacement element and the other element relative each other in order to obtain different operation modes of said system.

The present invention relates to apparatuses for use in performing a quantitative analysis of a turbid pharmaceutical sample, e.g. a tablet, a capsule or a similar sample forming a pharmaceutical dose. A pharmaceutical, turbid sample () is irradiated with an excitation beam () of radiation, e.g. near infrared radiation. The intensity of emitted radiation () from the sample () is detected as function of both the wavelength of the emitted radiation and the photon propagation time through said sample (). Optionally, the intensity of the emitted radiation () from the sample () is also detected in a spatially resolved manner.

Measuring technique

The present invention relates to a method for analysing the amount of free gas within a pharmaceutical sample. According to the invention the method comprises the following steps: providing a sample before an irradiating source; irradiating the sample with at least one beam of electromagnetic radiation; detecting radiation emitted through the sample and generating signals corresponding to the amount of free gas in the sample, and correlating the generated signals to at least one solid state parameter of the sample.
