Publication number: 20240036140Abstract: A technique for slice-specific correction of scan data recorded for at least two slices simultaneously of an examination object via an EPI-SMS is provided. The technique comprises recording slice separation reference scan data, generating scan data that is to be corrected, and recording phase-encoded navigator signals simultaneously for the at least two slices after an RF excitation pulse radiated into the examination object and before the recording of scan data to be corrected. The at least one navigator signal is recorded for each possible polarity and different phase-encoding of the navigator signals that is used. The technique further comprises separating the navigator signals simultaneously recorded for the at least two slices into single-slice navigator signals using the slice separation reference scan data, determining slice-specific correction data from the single-slice navigator signals, and correcting scan data that is to be corrected by means of the slice-specific correction data.Type: ApplicationFiled: July 27, 2023Publication date: February 1, 2024Applicant: Siemens Healthcare GmbHInventors: Mario Zeller, Adam Kettinger

Publication number: 20240036141Abstract: A joint k-space and image-space reconstruction imaging method and a device, relating to the field of magnetic resonance imaging. The method comprises: first, using the k-space parallel imaging method to reconstruct under-sampled image frames having auto-calibration signals of a subject obtained from multi-frame imaging required for the measurement of magnetic resonance parameters; and then performing reconstruction in image space for other under-sampled image frame data without auto-calibration signals. In the method, an accurate sensitivity map required for the SENSE method is generated from under-sampled data, without the need of additional acquisition. By means of the present method, images that are almost identical to those obtained by the traditional GRAPPA method and without obvious artifacts can be obtained at a speed which is four times faster than that by the traditional GRAPPA method.Type: ApplicationFiled: October 8, 2023Publication date: February 1, 2024Inventors: Yi ZHANG, Tao ZU, Dan WU

Publication number: 20240036142Abstract: In a method for slice-specific correction of scan data recorded for at least two slices simultaneously of an examination object using an EPI-SMS technique, navigator signals encoded in a slice selection direction using a bipolar readout gradient for the at least two slices temporally after a RF excitation pulse radiated into the examination object and temporally before the recording of scan data to be corrected may be simultaneously recorded. Mean navigator signal(s) from at least two of the recorded navigator signals of a same polarity may be determined. Single-slice navigator signals may be determined based on the mean navigator signal and a navigator signal having been recorded with the same polarity as the mean navigator signal(s), but with a different slice selection encoding. Slice-specific correction data from the single-slice navigator signals may be determined, and scan data may be corrected based on the slice-specific correction data.Type: ApplicationFiled: July 28, 2023Publication date: February 1, 2024Applicant: Siemens Healthcare GmbHInventors: Mario Zeller, Adam Kettinger

Publication number: 20240036147Abstract: Sidelink (SL) positioning of user equipments (UEs) is supported by assigning priority values to SL positioning operations, e.g., transmission or reception of SL positioning reference signals (PRS). The priority value, for example, may be (pre-)configured or provided to the physical (PHY) layer from higher layers. The UE selects resources for the SL positioning operations based on at least the priority value. The UE may reserve resources for the SL positioning operations, for example, using Layer 1 (L1) and/or Layer 2 (L2) control operations or by transmitting an indication that other UEs are to avoid using the resources. The priority values for the SL positioning operations may be used to resolve in-device conflicts, such as when the SL positioning operations conflict with other sidelink or non-sidelink operations.Type: ApplicationFiled: July 26, 2022Publication date: February 1, 2024Inventors: Gabi SARKIS, Gene Wesley MARSH, Dan VASSILOVSKI
