Abstract: The invention relates to a stool sample device [A?] for collecting a stool sample from a region of a human rectum, characterised in that it comprises an outer part and an inner part, wherein the outer part comprises an outer unit [G?], wherein an inner unit [E?] is mounted, further wherein the outer unit [G?] has a round tip and comprises openings for collecting sample; and the inner part comprises the inner unit [E?] fitted with gaskets [D?], further wherein the inner unit [E?] is equipped with a spiral-shaped part or snail placed at the tip end relative to the outer unit [G?] and with a handle for turning [B?] and pulling [C?] at the opposite end relative to the spiral-shaped part or snail, a first gasket [D?] is placed at the tip end of the inner unit [E?], and a second gasket is placed at the opposite end of the inner unit [E?] relative to the spiral-shaped part or snail; wherein the inner unit [E?] can be turned and pulled back by the handle [B?, C?].

Abstract: The present disclosure relates to a system for generating a predefined electrical signal in an MR scanner for use in electrical stimulation of a subject during MRI or functional MRI of said subject, wherein said MR scanner is located inside a shielded MRI room. The system comprises a control unit to be located outside the MRI room for generating an electrical signal and an electrical to optical converter to be located outside the MRI room for converting said electrical signal to a corresponding optical signal. An optical transmitting element, such as an optical fiber, is used for transmitting the optical signal into the MRI room, and an optical to electrical converter is used for converting the optical signal to said predefined electrical signal for electrical stimulation of the subject during magnetic resonance imaging. The optical to electrical converter is configured for being located inside the MRI room and for operation during magnetic resonance imaging.

Abstract: The present disclosure relates to a susceptibility artifact reducing vacuum bag for reducing local magnetic inhomogeneity inside a magnetic resonance imaging system, the vacuum bag comprising a mixture of diamagnetic composite material made of a diamagnetic material, such as pyrolytic graphite, and a filler material, the fraction of diamagnetic composite material and filler material selected such that the mixture has a net magnetic susceptibility corresponding substantially to the magnetic susceptibility of human tissue, the vacuum bag further comprising a valve for establishing an externally generated vacuum inside the vacuum bag.

Abstract: The present invention relates to a system and a method for monitoring/tracking the movement of an object in a location which is difficult to access, such as the movement of a patient in a clinical MRI scanner. This is achieved by an optical motion tracking system for determining the movement of an object at least partly located in a volume of difficult access and/or at least partly located in an electromagnetic field, said system comprising a borescope for imaging a pattern on the object or a surface part of the object with a camera, said pattern or surface part located adjacent to a distal end of the borescope and said camera attached to a proximal end of said borescope, and image processing means for calculating the movement of said pattern or surface part relative to the distal end of the borescope based on a plurality of frames/images captured by the camera.
