Patent number: 11402374Abstract: The invention relates to a method for the detection of target components that comprise label particles, for example magnetic particles (1). The method includes (a) collecting the target components at a binding surface (12, 112, 512) of a carrier (11, 111, 211, 311, 411, 511); (b) directing an input light beam (L1, L1a, L1b) into the carrier such that it is totally internally reflected in an investigation region (13, 313a, 313b) at the binding surface (12, 112, 512); and (c) determining the amount of light of an output light beam (L2, L2a, L2b) that comprises at least some of the totally internally reflected light. Evanescent light generated during the total internal reflection is affected (absorbed, scattered) by target components and/or label particles (1) at the binding surface (12) and will therefore be missing in the output light beam (L2). This can be used to determine the amount of target components at the binding surface (12) from the amount of light in the output light beam (L2, L2a, L2b).Type: GrantFiled: May 8, 2015Date of Patent: August 2, 2022Assignee: Siemens Healthineers Nederland B.V.Inventors: Coen Adrianus Verschuren, Dominique Maria Bruls, Albert Hendrik Jan Immink, Femke Karina De Theije, Thea van der Wijk, Alexander Marc Van Der Lee, Johannes Joseph Hubertina Barbara Schleipen

Patent number: 11243199Abstract: The invention relates to a carrier with a binding surface at which target components that comprise label particles, for example magnetic particles, can collect and optionally bind to specific capture elements. An input light beam (L1) is transmitted into the carrier and totally internally reflected at the binding surface. The amount of light in the output light beam (L2) and optionally also of fluorescence light emitted by target components at the binding surface is then detected by a light detector. Evanescent light generated during the total internal reflection is affected (absorbed, scattered) by target components and/or label particles at the binding surface and will therefore be missing in the output light beam (L2). This can be used to determine the amount of target components at the binding surface from the amount of light in the output light beam (L2, L2a, L2b).Type: GrantFiled: April 15, 2015Date of Patent: February 8, 2022Assignee: Siemens Healthineers Nederland B.V.Inventors: Coen Adrianus Verschuren, Dominique Maria Bruls, Albert Hendrik Jan Immink, Femke Karina De Theije e/v Wijgergangs, Thea van der Wijk, Alexander Marc Van Der Lee, Johannes Joseph Hubertina Barbara Schleipen

Patent number: 11154199Abstract: A medical imaging system for identifying a target structure (TS), e.g. a tumor, in a biological tissue. A hyperspectral camera system is used for imaging a surface area (A1) of the tissue (BT), e.g. with a limited spectral resolution, but enough to allow identification of suspicious areas where the target structure (TS) may be, e.g. such areas can be visually indicated on a display to the operator. A probe (PR), e.g. an optical surface probe, is used to provide probe measurement of a smaller surface area (A2) of the tissue, but with more information indicative of the target structure. The probe is selected to provide a higher specificity with respect to identification of the target structure than the hyperspectral camera (HSC). The hyperspectral processing algorithm (PP) is then calibrated based on probe measurement data performed within the suspicious areas, thus providing a calibrated hyperspectral processing algorithm resulting in images with an enhanced sensitivity to identify the target structure.Type: GrantFiled: January 22, 2014Date of Patent: October 26, 2021Assignee: Koninklijke Philips N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Johannes Joseph Hubertina Barbara Schleipen, Christian Reich, Gerhardus Eilhelmus Lucassen, Manfred Mueller, Vishnu Vardhan Pully

Patent number: 9863863Abstract: The invention relates to a sensor apparatus (100) and a method for detecting clusters with magnetic particles in a sample. The sample is provided in at least one sample chamber (114) of a substantially planar cartridge (110) that is exposed to a modulated magnetic field (Bxz, Byz) generated by a magnetic field generator (190). The sample chamber (114) is illuminated with excitation light (L0), and the resulting output light (Ls) is detected by a light detector (180). The magnetic field (Bxz, Byz) may particularly rotate, inducing a corresponding rotation of clusters which in turn induces a variation of the detection signal (S). According to a preferred embodiment, excitation light (L0) is focused onto blocking spots (173) behind the sample chamber (114), thus shielding the light detector (180) from direct illumination.Type: GrantFiled: November 6, 2012Date of Patent: January 9, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Johannes Joseph Hubertina Barbara Schleipen, Menno Willem Jose Prins, Andrea Ranzoni

Patent number: 9804089Abstract: A sensing device (100) detects a target substance (2) in an investigation region (113). The sensing device (100) includes a sensing surface (112) with an investigation region (113) and a reference region (120). The sensing device (100) further includes a reference element (121) located at the reference region (120). The reference element (121) is adapted to shield the reference region (120) from the target substance (2) such that light reflected at the reference region (120) under total internal reflection conditions remains unaffected by the presence or absence of the target substance (2). This allows measuring a property, typically the intensity, of light reflected at the reference region (120) independent of the presence or absence of the target substance (2). This measured property of the reflected light can be used for performing a correction of light reflected at the investigation region (113).Type: GrantFiled: February 8, 2010Date of Patent: October 31, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Dominique Maria Bruls, Toon Hendrik Evers, Johannes Joseph Hubertina Barbara Schleipen

Patent number: 9339813Abstract: The invention relates to a substance determining apparatus for determining a substance within a fluid. Particles attach the substance and bind to a binding surface (30), wherein a sensing signal is generated depending on the bound particles. Binding events indicating a binding of a particle on the binding surface (30) are determined from the generated sensing signal, and the substance within the fluid is determined based on the determined binding events. During a procedure of determining a substance within a fluid, particles may bind to the binding surface and may leave the binding surface. Therefore, during this procedure a number of binding events can be determined being much larger than the number of bound particles. The determination of the substance within the fluid can therefore be based on a very large amount of data, thereby increasing the accuracy of determining the substance within the fluid.Type: GrantFiled: December 10, 2010Date of Patent: May 17, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Josephus Arnoldus Henricus Maria Kahlman, Joannes Baptist Adrianus Dionisius Van Zon, Johannes Joseph Hubertina Barbara Schleipen, Derk Jan Wilfred Klunder, Toon Hendrik Evers, Ron Martinus Laurentius Van Lieshout
