Patent number: 10605880Abstract: A method for performing 3D body imaging includes performing a 3D MRI acquisition of a patient to acquire k-space data and dividing the k-space data into k-space data bins. Each bin includes a portion of the k-space data corresponding to a distinct breathing phase. 3D image sets are reconstructed from the bins, with each 3D image set corresponding to a distinct k-space data bin. For each bin other than a selected reference bin, forward and inverse transforms are calculated between the 3D image set corresponding to the bin and the 3D image set corresponding to the reference bin. Then, a motion corrected and averaged image is generated for each bin by (a) aligning the 3D image set from each other bin to the 3D image set corresponding to the bin using the transforms, and (b) averaging the aligned 3D image sets to yield the motion corrected and averaged image.Type: GrantFiled: May 9, 2017Date of Patent: March 31, 2020Assignees: Siemens Healthcare GmbH, Cedars-Sinai Medical CenterInventors: Xiaoming Bi, Jianing Pang, Zhaoyang Fan, Matthias Fenchel, Gerhard Laub, Debiao Li

Patent number: 10561467Abstract: The invention relates to an interventional apparatus comprising an interventional device with a handle (6). The handle comprises a) a first guide (20, 51) guiding an optical fiber, which is also guided within the interventional device, from a first proximal opening (14) of the handle to a distal portion (21) of the handle, wherein the first guide only has radii of curvature being larger than 10 mm, and b) a second guide (22) for guiding an elongated interventional instrument from a second proximal opening (13) of the handle to the distal portion of the handle. Since the first guide is relatively straight, the optical fiber is substantially not bent or only slightly bent and the likelihood that the interventional instrument and the optical fiber press against each other can be significantly reduced. This allows for an improved accuracy of determining the position of the interventional device by optical shape sensing.Type: GrantFiled: September 6, 2015Date of Patent: February 18, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Franciscus Reinier Antonius Van Der Linde, Franciscus Johannes Gerardus Hakkens, Cornelis Gerardus Maria De Haas, Cornelius Antonius Nicolaas Maria Van Der Vleuten, Adrianus Wilhelmus Dionisius Maria Van Den Bijgaart, Maurice Hubertus Elisabeth Van Der Beek
