Patent number: 11966037Abstract: Disclosed herein are sample dishes for use with microscopes that are simple to mount on a microscope and facilitate easy manipulation of tissue samples disposed thereon during imaging as well as methods of their use. A sample dish comprises an optical interface and, optionally, a support member that holds the optical interface. The optical interface of a sample dish is suitably transparent and planar such that a focal plane of a microscope can reside uniformly at or within a surface of a sample during imaging. In certain embodiments, a support member comprises a dish for holding excess fluid. In certain embodiments, a sample dish comprises separation ribs. In certain embodiments, a sample dish comprises one or more manipulation members (e.g., tabs). In certain embodiments, a sample dish is used with an imaging artifact reducing fluid.Type: GrantFiled: May 9, 2022Date of Patent: April 23, 2024Assignee: SamanTree Medical SAInventors: Etienne Shaffer, Jonathan Abel Pirolet, Frédéric Schmitt, Bastien Rachet, Diego Joss, Aurèle Timothée Horisberger

Publication number: 20210248746Abstract: Systems and methods to identify and/or reduce or eliminate sample motion artifacts are disclosed. Sample motion artifacts may be reduced or eliminated using scan patterns where an acquisition time difference between when perimeter pixels in adjacent tiles are acquired is reduced, as compared to a conventional raster scan to reduce or eliminate discontinuities that would otherwise appear at tile boundaries in an image. In some embodiments, test images acquired using relatively small test scan patterns or intensities of test points acquired at different times may be compared to determine whether sample motion has occurred. In some embodiments, intensity of adjacent pixels at a tile boundary are compared. In some embodiments, intensity of one or more single pixels is monitored over time to determine whether sample motion has occurred over a period of time. In some embodiments, a flattening or reshaping tool may be used to suppress sample motion during imaging.Type: ApplicationFiled: February 12, 2021Publication date: August 12, 2021Inventors: Andrey Naumenko, Aurèle Timothée Horisberger, Diego Joss, Frédéric Schmitt, Etienne Shaffer, Jonathan Abel Pirolet, Bastien Rachet, Andrew Logvinov

Publication number: 20200309649Abstract: Disclosed herein are receptacles for use in staining and/or rinsing samples. In some embodiments, a receptacle includes a container and a container top. A container may be sized and shaped to contain fluid and a sample submerged in the fluid. The fluid may be, for example, staining agent solution or rinsing solution. In some embodiments, a kit is provided that includes a first receptacle that includes a container partially filled with staining agent solution and a second receptacle that includes a container partially filled with rinsing solution. In some embodiments, a receptacle includes a container and a basket that is positionable in the container. A basket may include a permeable sample holding element that is permeable to fluid in a container so that samples can be sufficiently stained or rinsed. In some embodiments, a receptacle is a single-dose receptacle that is used intraoperatively (e.g., in an operating room).Type: ApplicationFiled: March 2, 2020Publication date: October 1, 2020Inventors: Etienne Shaffer, Aurèle Timothée Horisberger, Frédéric Schmitt, Bastien Rachet

Publication number: 20200284703Abstract: Disclosed herein are staining agent solutions for use in fluorescence microscopy. One example of fluorescence microscopy in which the staining agent solutions are useful is intraoperative confocal microscopy. Intraoperative confocal microscopy can be used, for example, to assess margins of resected cancerous tissue. Example staining agent solutions include acridine orange, where the pH of the solution is from 6 to 8, for example from 6.8 to 7.4. The solution may include a phosphate-buffered saline (PBS). The solution may be isotonic. The solution may comprise one or more of potassium dihydrogen phosphate, disodium hydrogen phosphate, and sodium chloride. In some embodiments, the staining agent solution does not comprise acetic acid (e.g., an acetate buffer). Staining agent solutions disclosed herein may reduce adverse impacts to tissue resulting from staining. Staining agent solutions disclosed herein may preserve normal appearance of tissue.Type: ApplicationFiled: March 2, 2020Publication date: September 10, 2020Inventors: Etienne Shaffer, Aurèle Timothée Horisberger, Frédéric Schmitt, Bastien Rachet
