Patent number: 10765558Abstract: An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can detect at least one of acoustic reflectivity, optical reflectivity, optical path difference, positioning of intraocular pressure measurement arrangement with respect to the eye, orientation of intraocular pressure measurement arrangement with respect to the eye, shape of cornea and corneal thickness. At least one source can produce acoustic, nonlinear acoustic, mechanical or a nonlinear mechanical wave from a distance, coupling to the eye to generate at least one surface wave. Upon triggering data acquisition, at least one surface wave from a distance from the eye can be detected to extract surface wave information with pressure information of the eye being based on the surface wave information.Type: GrantFiled: March 5, 2018Date of Patent: September 8, 2020Assignee: PHOTONO OYInventors: Edward Haeggström, Ari Salmi, Ivan Kassamakov, Heikki Nieminen, Timo Rauhala, Kalle Hanhijärvi, Antti Kontiola

Publication number: 20190323820Abstract: An artifact for improving the vertical resolution of radiation-based imaging is presented. The artifact has a stepped thickness profile with steps. Adjacent steps are arranged to interact differently with radiation used in the radiation-based imaging. Thus, it is possible to identify which step is, in each imaging situation, vertically closest to the imaging plane related to the radiation-based imaging. Thus, a pre-determined vertical position-value related to the closest one of the steps can be used as a vertical position-value related to a radiation-based imaging result obtained in the imaging situation.Type: ApplicationFiled: December 12, 2017Publication date: October 24, 2019Inventors: Ivan KASSAMAKOV, Edward HAEGGSTRÖM, Niklas SANDLER, Anton NOLVI, Tapani VIITALA, Alejandro Garcia PEREZ

Publication number: 20180256089Abstract: An assessment method is disclosed to determine at least one of macro-topology, milli-topology, micro-topology and nano-topology of at least one interface of at least two media using topology of the interface. Topology information of the interface is processed by performing segmentation of volume information of the obtained information from background information of the obtained information. Reference surface information is generated and information on voids is obtained and analyzed to provide multivalued surface shape information. Quantitative mapping of the information on voids is performed using the multivalued surface shape information for determining at least one of macro-topology, milli-topology, micro-topology and nano-topology of the interface.Type: ApplicationFiled: May 11, 2018Publication date: September 13, 2018Applicant: University of OuluInventors: Heikki Nieminen, Tuomo Ylitalo, Simo Saarakkala, Edward Haeggström
