The present disclosure relates to an antenna assembly for an imaging method, a use of an antenna assembly and a tomography system, in particular for MRI or simultaneous MR-PET / SPECT. An antenna assembly for an imaging method comprises at least two adjacent antennas, wherein each of the at least two antennas is designed as a J-pole antenna with a radiation section and a feed section. The at least two antennas are arranged alternately at a first angle and a second angle different from the first angle in relation to a reference surface. In this way, effective decoupling of the two antennas is achieved by simple means.

A method is used to manufacture a surgical instrument including a first tube, and a second tube. The first tube extends from a proximal first end portion to a distal first end portion. The second tube extends from a proximal second end portion to a distal second end portion. The second tube is positioned coaxially within the first tube with the distal second end portion positioned adjacent to the distal first end portion. The second tube defines a lumen. The sensor is secured proximal to the distal second end portion of the second tube. A die is engaged against a distal first end portion of the first tube while first tube rotates about its own longitudinal axis; and the die is simultaneously moved relative to the distal first end portion of the first tube along a predetermined path to form a predetermined shape.

The present invention relates to a method and apparatus for measuring the surface viscoelasticity of biological tissue. The method includes: step S1, driving the surface of the biological tissue in the direction normal to the surface of the surface to move it to a certain displacement along the normal and then holding it; step S2, using a sensor to measure the time-dependent mechanical response of the surface of the biological tissue during the execution of step S1; and step S3, outputting viscoelastic characteristic data of the surface of the biological tissue by a processing module in accordance with the mechanical response acquired by the sensor. The measurement method of the present invention is intended to more scientifically and reliably detect the surface viscoelasticity of biological tissue, particularly human skin.

There is provided a method of automatically segmenting a magnetic resonance (MR) image, comprising: segmenting a residual breast from an input MR image depicting the residual breast with implant after surgical removal of breast tissue, wherein the segmentation of the residual breast includes breast tissue remaining after the surgical removal, feeding the segmented residual breast into a fibroglandular tissue (FGT) segmentation ML model, and obtaining a segmentation of FGT from the segmented residual breast as an outcome of the FGT segmentation ML model. Optionally, the FGT segmentation ML model is trained on a FGT segmentation training dataset of FGT segmentation records, each FGT segmentation record including a MR image of a segmented whole breast of a control subject that excludes an implant and on which no surgical removal of breast tissue has been performed, and a ground truth comprising a segmentation of the FGT depicted in the segmented whole breast.

An aspiration device (110) for measuring the viscoelastic deformability of biological tissues and synthetic materials comprises a probe head (11), a probe channel (41), a pressure unit (20), a pressure sensor (31) and a control unit (60). The first probe channel (41) is connecting the pressure unit (20) providing a vacuum with the probe head and includes the pressure sensor (31) detecting the pressure in the first probe channel (41). The first probe channel (41) has a distal end (141) leading with its lower open end (144) through the top wall (14) into the cavity (15) of the probe head. The cavity (15) comprises either an opening (16) in the side or top wall (13, 14) or a second probe channel connected with a valve. A measurement cycle comprises applying under pressure in the first probe channel (41), measuring the under pressure with the pressure sensor (31), detecting a change of under pressure increase over time (301, 401), increasing the under pressure to a predetermined maximum under pressure (303), decreasing the under pressure beyond this point in time and detecting a change of under pressure decrease over time (302, 402).

A minimally invasive device, containing a pressure channel, camera, and optical fiber imaging probe, to measure the stiffness of tissues in vivo and ex vivo is disclosed. The device is inserted into a patient and navigated to a tissue of interest, where stiffness is evaluated by applying suction and measuring the elongation or by applying compression force and measuring the compression of the tissue. Biopsies can be taken for further analysis, or tissue can be removed using an ablation laser. Small fluorescent molecules or therapeutics can also be delivered for improved visualization and targeted treatment. As such, this technology may be used to evaluate the stiffness of biomaterials as well as tissues and organs that are difficult to access, allowing for simultaneous diagnosis, treatment, and excision of diseased tissues.

The present invention relates to a method and a device for measuring the surface viscoelasticity of a biological tissue. The method comprises the following steps: S1: driving a surface of the biological tissue to move a defined distance in the normal direction of the surface and subsequently holding the surface in place; S2: measuring the mechanical response of the surface of the biological tissue as a function of time with a sensor during the execution of step S1; and S3: outputting the viscoelastic characteristics of the surface of the biological tissue by means of a processing module based on the mechanical response detected by the sensor. The measurement method according to the present invention aims to determine the surface viscoelasticity of a biological tissue, in particular human skin, in a more scientifically sound and reliable manner.
