A system (10, 100, 300, 400) is provided for identifying certain targeted cells or tissues in a body. The system (10, 100, 300, 400) preferably includes at least one ingestible capsule that accommodates or supports (20) at least one of an illuminating module (30, 114, 322, 422, 452), a detecting module (40, 124, 324, 424, 434, 454), an imaging module (50, 326, 432, 456), a control module (60), or a reservoir (70, 132, 312, 412, 442) suitable for retaining and releasing one or more nanoshells. A method (200) is also provided for employing the system (10, 100, 300, 400) to detect, image or otherwise interact with diseased or abnormal cells and/or tissues in a body. The system (10, 100, 300, 400) and method (200) provided allow for improved diagnosing, treating and imaging techniques and for increased sensitivity and specificity in efficiently distinguishing targeted diseased or abnormal cells or tissue from surrounding healthy cells or tissue.

摘要:
The present invention relates to an apparatus 100 and, a method and a computer program for determining a parameter indicative of a tissue type of an associated tissue 116. In particular, the invention relates to an apparatus 100 comprising a spectrometer 102, which spectrometer comprises a light source 104 and a detector 106, 108 arranged to measure an optical spectrum. This enables determination of a first parameter being indicative of a bile concentration. As the inventors of the present invention have made the insight that bile concentration may serve as a discriminative feature for different tissue types, the apparatus is arranged to determine a second parameter indicative of a tissue type based on a concentration of bile. According to a specific embodiment, the apparatus further comprises an interventional device 112.

The present invention relates to an apparatus, a method and a computer program for determining a lipid-water ratio and a scattering parameter of a sample. In particular, the invention relates to an apparatus comprising a light source and a detector arranged to measure an optical parameter at various wavelengths, where the wavelengths are selected so that at two of the wavelengths the absorption coefficients for both water and lipids are substantially identical. This enables determination of a scattering parameter. A further measurement at a third wavelength enables determination of a water-lipid ratio. According to a specific embodiment, the light source and the detector are arranged in relation to an interventional device, so as to be able to examine a tissue in terms of lipid-water ratio and scattering during an intervention.
摘要:
The present invention deals with discrimination of malignant tissue from normal and benign tissue in a single patient on the basis of optical spectroscopic measurements. Starting from spectroscopic measurements in normal tissue, reference values are obtained for the normal class. With spectroscopic measurements in other tissues data points can be assigned to new class(es) when the spectral characteristics fall outside a threshold defining the reference class. Thresholds between different classes can also be defined. Finding (the transition to) malignant tissue is based on comparing the spectroscopic values to the classification threshold discriminating normal and benign versus malignant tissue. Thus, the basis of normal spectroscopic measurements is tuned to the individual patient characteristic. Discriminating the normal plus benign and malignant from that reference is more efficient compared to the reference of the all patient database.
摘要:
A needle comprises an elongated first shaft element with a C-shaped cross section and an elongated second shaft element with a C-shaped cross section. The first shaft element and the second shaft element are adapted to be detachably connected to each other. This is achieved by an overlap of respective end sections of the first and second shaft elements. Within the channel formed by the shaft elements, an optical probe may be accommodated from which the shaft elements may be removed by separating the two shaft elements from each other.
