Publication number: 20230157625Abstract: A system for providing information for diagnosing preterm birth risk includes: two or more transmit electrodes, contacting cervical tissues, for applying a plurality of first signals at different frequencies to the cervical tissues, two or more detect electrodes, contacting the cervical tissues, for detecting a plurality of second signals generated in response to the first signals, the second signals corresponding to the first signals, and a source configured to generate a plurality of signals. The system obtains a plurality of impedances of the cervical tissues based on the first and the second signals and applies data quality requirements for diagnosing the preterm birth risk. The data quality requirements include checking at least one of signal generation, signal reception, impedance calculation, quality of the first signals, quality of the second signals, and the impedances.Type: ApplicationFiled: November 22, 2021Publication date: May 25, 2023Inventors: Gordon SCARTH, Jack MONDRY, Byunggaun PARK, Hyunseon GONG, Timothy James HEALEY, Dilichukwu ANUMBA

Patent number: 8988505Abstract: A system for detecting a position of an object such as a surgical tool in an image guidance system includes a camera system with a detection array for detecting visible light a processor arranged to analyze the output from the array. Each object to be detected carries a single marker with a pattern of contrasted areas of light and dark intersecting at a specific single feature point thereon. The pattern includes components arranged in an array around the specific location arranged such that the processor is able to detect an angle of rotation of the pattern around the location and which are different from other markers of the system such that the processor is able to distinguish each marker from the other markers.Type: GrantFiled: October 19, 2010Date of Patent: March 24, 2015Assignee: Imris IncInventors: Shawn Schaerer, Gordon Scarth, Steven Robbins

Patent number: 8570037Abstract: An RF coil used for MR imaging is designed so that it remains in place in the field of view of an X-Ray imaging system and comprises a support board on which copper conductive traces and copper printed capacitors are carried. The attenuation of the X-Rays caused by the copper traces is visible in the radiation image but this is compensated by arranging the non-conductive material of the support board such that the attenuation of substantially the whole of the RF coil located within the field of view is substantially constant throughout the field of view.Type: GrantFiled: June 29, 2010Date of Patent: October 29, 2013Assignee: Imris Inc.Inventors: Wayne Schellekens, Gordon Scarth

Patent number: 8369929Abstract: A patient table for a common imaging system including Magnetic Resonance and X-ray retains the patient stationary in position prior to, during and subsequent to the imaging and includes a base, a patient support portion cantilevered from the base and a mattress. The RF posterior coil portions for the head and for the chest can be inserted into and removed from an operating position underneath the head and chest of the patient while patient remains supported. The chest coil is inserted from one edge in a cavity in the mattress which is reinforced by a sleeve. The signal communication cable from the chest coil is routed in front of the mattress and over the mattress so as to not to be exposed at the sides. The head coil is carried on a base plate of the patient support alongside the head support which remains in place.Type: GrantFiled: December 11, 2008Date of Patent: February 5, 2013Assignee: Imris Inc.Inventors: Gordon Scarth, Alexander Shvartsberg, Franjo Vugrin, Wybrandus T.

Patent number: 8295906Abstract: Radiation therapy of a lesion within a patient is guided to take into account movement of the lesion caused by respiration and/or cardiac effects by using MRI to image the patient while on the treatment support to obtain a series of images of a location of the lesion within the patient while obtaining data relating to respiration and/or cardiac function of the patient to generate lesion movement data as a function of respiration and/or cardiac function. After the magnet is removed from the bunker, during the radiation therapy, real time data relating to respiration and/or cardiac function of the patient is used to guide the radiation therapy using the lesion movement data obtained during the imaging.Type: GrantFiled: August 20, 2008Date of Patent: October 23, 2012Assignee: Imris IncInventors: John K. Saunders, David Graves, Gordon Scarth

Patent number: 8073524Abstract: A patient imaging system includes a patient support table and an MRI system including a cylindrical magnet. The magnet defines a cylindrical bore for receiving the patient on the table where the magnet is mounted for rotation about a vertical axis on a slew ring carried on rails allowing longitudinal movement. The magnet is arranged in a two or three room diagnostic configuration in which a holding bay houses the magnet and the diagnostic patients are organized in the three rooms each cooperating with the magnet bay. A control system is provided for inputting data defining different locations or conditions of the magnet relative to its environment and for each of the different conditions data is stored defining a respective set of shimming parameters so that the control system automatically inputs the shimming parameters and adjusts the shimming as the magnet is moved or a secondary imaging system is brought up to the magnet.Type: GrantFiled: November 8, 2007Date of Patent: December 6, 2011Assignee: Imris Inc.Inventors: John K.

Method and apparatus for operating variable optical attenuator by modulating the attenuation thereof
Publication number: 20050019032Abstract: A method and apparatus are disclosed for operating an eVOA by modulating its attenuation. If an optical signal power is below a loss of signal (LOS) power threshold the eVOA attenuation is set to a maximum attenuation and then, periodically and quickly decreased and increased in steps while checking for the presence of optical signals above the LOS power threshold. The method is also used for operating a multiplicity of eVOAs while minimizing the risk of damage to optical network equipment.Type: ApplicationFiled: July 15, 2003Publication date: January 27, 2005Inventors: Gordon Scarth, Robert Bierman, Steve Grabner
