Publication number: 20220330808Abstract: An object sizing system sizes an object positioned within a patient. The object sizing system identifies a presence of the object. The object sizing system navigates an elongate body of an instrument to a position proximal to the object within the patient. An imaging sensor coupled to the elongate body captures one or more sequential images of the object. The instrument may be further moved around within the patient to capture additional images at different positions/orientations relative to the object. The object sizing system also acquires robot data and/or EM data associated with the positions and orientations of the elongate body. The object sizing system analyzes the captured images based on the acquired robot data to estimate a size of the object.Type: ApplicationFiled: May 2, 2022Publication date: October 20, 2022Inventors: David S. Mintz, David M. Schummers, Prasanth Jeevan, Hedyeh Rafii-Tari, Ritwik Ummalaneni

Publication number: 20220330812Abstract: A contrast sensitivity measurement apparatus (1) generates a stimulating image to be output to an external display device (20) for measuring contrast sensitivity of a user. An image scale setting unit (12) determines the spatial frequency in units of pixels on the basis of an observation distance, physical characteristics of the external display device (20), and visual characteristics of a human. A carrier waveform generation unit (13) generates a luminance map in which a change of luminance along a first axis follows the spatial frequency. A contrast map generation unit (14) generates a contrast map in which contrast gradually decreases from one end to another end along a second axis, and an equal contrast line forms a given waveform. A stimulating image synthesis unit (15) generates the stimulating image by synthesizing the luminance map and the contrast map.Type: ApplicationFiled: September 2, 2019Publication date: October 20, 2022Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Kenchi HOSOKAWA, Kazushi MARUYA

Publication number: 20220330814Abstract: Method for measuring the stability of a tear film of a patient using a device including a backlit translucent plate provided with a test chart positioned in front of at least one eye of the patient, at least one digital photographic camera connected to a computing system, and a camera lens pointing towards the patient's eye to photograph a reflection of a test chart pattern on the patient's. The method includes, from a starting time constituted by an eyelid blink, capturing a succession of images, detecting a succession of micro-movement areas in the images, and computing and storing data on the position, surface area and number of micro-movement areas of the tear film in each image, and computing and storing surface area and number of micro-movement areas of the tear film, and a measurement of the amplitude of the micro-movement areas as a function of time.Type: ApplicationFiled: September 11, 2020Publication date: October 20, 2022Inventors: Yves-Vincent Brottier, Arnaud Obin, Nelson Perrin

Publication number: 20220330816Abstract: Methods and apparatus for producing images of the retina or fundus with improved quality and visualization of its features. This is accomplished by adjustment of specific pupil size, pupil position, detector pinhole size and wavelength parameters of the instrument to give improved image quality as described by a chosen image quality metric. Methods are less complex than adaptive optics and give an improved image in a region of interest and potentially over a larger field of view. Thus, it will be useful in instruments designed for the screening of retinal disease(s). The methodology is applicable to an individual's eye, on the basis of either the group that said individual falls into or measurements of the quality of their eye's optics. As described herein, the settings (including optimum pupil size, pupil position, detector pinhole size and/or wavelength for imaging) can be chosen to give improved the retinal image quality.Type: ApplicationFiled: April 18, 2022Publication date: October 20, 2022Inventors: Melanie CW Campbell, Julia Zangoulos
