Publication number: 20160290926Abstract: The disclosure relates to measurement and classification of tissue structures in samples using a combination of light imaging and spectroscopy, in particular although not necessarily exclusively for detection of tumours such as basal cell carcinoma or breast tumours in tissue samples. Embodiments disclosed include a method of automatically identifying tissue structures in a sample, the method comprising the steps of: measuring (1702, 1703) a response of an area of the sample to illumination with light; identifying (1704) regions within the area having a measured response within a predetermined range; determining (1705) locations within the identified regions; performing (1706) spectroscopic analysis of the sample at the determined locations; and identifying (1707) a tissue structure for each region from the spectroscopic analysis performed on one or more locations therein.Type: ApplicationFiled: March 21, 2014Publication date: October 6, 2016Applicants: The University of Nottingham, Royal Holloway University of LondonInventors: Ioan NOTINGHER, Kenny KONG, Christopher ROWLANDS, Hywel WILLIAMS, Iain LEACH, Sandeep VARMA, William PERKINS, Alexey KOLOYDENKO

Publication number: 20160135669Abstract: A fluid delivery system for use with an endoscope. Certain embodiments of the invention include a single, large fluid source and pump installed upon an operator console, in combination with a small fluid reservoir and pump installed within a proximal connector of the imaging endoscope, multiple fluid sources that feed a common fluid channel that are pressurized by a common pump, multiple fluid sources that feed dedicated fluid channels that are pressurized by dedicated pumps, and a small fluid reservoir and pump installed within a handheld manual controller of the imaging endoscope. The fluid delivery endoscopic systems of the present invention provide the user with the flexibility of changing fluids either in advance of a procedure or on-the-fly as needed, instead of relying on fixed fluid sources only.Type: ApplicationFiled: January 21, 2016Publication date: May 19, 2016Applicant: Boston Scientific Scimed, Inc.Inventors: Dennis R.

Publication number: 20160091705Abstract: The information budget of a light field microscope is increased by increasing the field of view and image circle diameter of the microscope, while keeping the ratio of overall magnification of the microscope to the numerical aperture of the microscope unchanged. Alternatively, the information budget is increased by increasing the field of view and image circle diameter of the microscope by a first factor, while increasing the ratio of overall magnification of the microscope to the numerical aperture of the microscope by a smaller, second factor. In some cases, an infinity-corrected light field microscope has an overall magnification that is greater than the nominal magnification of the objective lens.Type: ApplicationFiled: September 28, 2015Publication date: March 31, 2016Applicant: Massachusetts Institute of TechnologyInventors: Moshe Ben Ezra, Edward Boyden, Christopher Rowlands, Young Gyu Yoon

Patent number: 8746666Abstract: A media carrier, adapted to hold a plurality of pieces of magnetic media, is disclosed. This media carrier can be placed on the workpiece support, or platen, allowing the magnetic media to be processed. In some embodiments, the media carrier is designed such that only one side of the magnetic media is exposed, requiring a robot or other equipment to invert each piece of media in the carrier to process the second side. In other embodiments, the media carrier is designed such that both sides of the magnetic media are exposed. In this scenario, the media carrier is inverted on the platen to allow processing of the second side.Type: GrantFiled: May 5, 2011Date of Patent: June 10, 2014Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Richard Hertel, Julian Blake, Edward Macintosh, Alexander Kontos, Frank Sinclair, Christopher Rowland, Mayur Jagtap, Sankar Ganesh Kolappan

Patent number: 8501624Abstract: An ion source that utilizes exited and/or atomic gas injection is disclosed. In an ion beam application, the source gas can be used directly, as it is traditionally supplied. Alternatively or additionally, the source gas can be altered by passing it through a remote plasma source prior to being introduced to the ion source chamber. This can be used to create excited neutrals, heavy ions, metastable molecules or multiply charged ions. In another embodiment, multiple gasses are used, where one or more of the gasses are passed through a remote plasma generator. In certain embodiments, the gasses are combined in a single plasma generator before being supplied to the ion source chamber. In plasma immersion applications, plasma is injected into the process chamber through one or more additional gas injection locations. These injection locations allow the influx of additional plasma, produced by remote plasma sources external to the process chamber.Type: GrantFiled: December 4, 2008Date of Patent: August 6, 2013Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Bon-Woong Koo, Victor Benveniste, Christopher A.

Patent number: 8357148Abstract: A multi-functional endoscopic system, for use in electrosurgical applications, that includes an imaging endoscope that may be used in combination with various electrosurgical devices, all of which are sufficiently inexpensive to manufacture, such that the endoscope and electrosurgical devices are considered single use, disposable items. The multi-functional endoscopic system of the present invention is suitable for use with a variety of common electrosurgical devices that require electrical/electronic support in order to function. The electrical/electronic support for these electrosurgical devices (e.g., an electrosurgical generator and associated controls) is integrated with the operator console of the imaging endoscope of the multi-functional endoscopic system of the present invention, rather than provided as a separate device.Type: GrantFiled: September 29, 2005Date of Patent: January 22, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Dennis R. Boulais, Michael S. Banik, Vincent Turturro, Christopher Rowland, David Hoffman, John P. O'Connor
