A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koktzoglou et al. (US 2014/0018666) in view of Sorensen et al. (2005 – Cited in IDS).
Koktzoglou et al. discloses the subject matter substantially as claimed except for wherein the CMR parameter is a two-dimensional plane. However, Sorensen et al. teaches in the same field of endeavor it is well known to select a two-dimensional imaging plane and a two-dimensional cross-section image from the imaging plane (“Interactive planar reformatting and two-dimensional quantification”; page 285). Therefore, it would have been obvious to one of ordinary skill in the art to have provided Koktzoglou et al. with selecting a two-dimensional plane as taught by Sorensen et al. in order to allow visualization of arbitrary imaging planes (“Interactive planar reformatting and two-dimensional quantification”; page 285).
Claim(s) 3-7, 12, and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koktzoglou et al. (US 2014/0018666) in view of Li et al. (US 2017/0074959).
With respect to claim 3, Koktzoglou et al. discloses the subject matter substantially as claimed except for acquisition time. However, Li et al. teaches in the same field of endeavor known acquisition time of at least 5 minutes and less than 30 minutes ([0046]). Therefore, it would have been obvious to one of ordinary skill in the art to have provided Koktzoglou et al. with acquisition time for at least 5 minutes and less than 30 minutes as taught by Li et al. as it is well known in the art.
With respect to claims 4-7 and 12, Koktzoglou et al. discloses the subject matter substantially as claimed except for identifying the cardiac or respiratory phase; organizing the acquired CMR imaging data according to the identified cardiac or respiratory phase; and reconstructing the 3D image. However, Li et al. teaches in the same field of endeavor identifying the cardiac or respiratory phase ([0045]); organizing the acquired CMR imaging data according to the identified cardiac or respiratory phase ([0045]); and reconstructing the 3D image ([0035]). Therefore, it would have been obvious to one of ordinary skill in the art to have provided Koktzoglou et al. with organizing the identified cardiac or respiratory phase for image reconstruction as it is well known in retrospective reconstruction.
With respect to claim 16, Li et al. discloses imaging for at least 400 ms ([0030]).
Claim(s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koktzoglou et al. (US 2014/0018666) in view of Li et al. (US 2017/0074959). as applied to claim 7 above, and further in view of Chen et al. (US 10,317,499).

However, Chen et al. teaches in the same field of endeavor is it well known in iterative reconstruction to identify and compare an artifact to a predetermined threshold (col. 6, lines 19-32). Therefore, it would have been obvious to one of ordinary skill in the art to have provided Koktzoglou et al. with identifying and comparing artifact level thresholds in order to provide artifact reduction and/or elimination (col. 6, lines 19-32).
Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koktzoglou et al. (US 2014/0018666) in view of Li et al. (US 2017/0074959). as applied to claim 4 above, and further in view of Bystrov et al. (US 2009/0154783).
Koktzoglou et al. in view of Li et al. discloses the subject matter substantially as claimed except for identifying a short axis, a long axis or a 4-chamber imaging plane. However, Bystrov et al. teaches in the same field of endeavor identifying short and long axis are known imaging views in cardiac imaging ([0037]). Therefore, it would have been obvious to one of ordinary skill in the art to have provided Koktzoglou et al. with identifying short and long axis as taught by Bystrov et al. as it is well known in cardiac imaging ([0037]).
Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Koktzoglou et al. (US 2014/0018666) in view of Li et al. (US 2017/0074959). as applied to claim 4 above, and further in view of Keupp et al. (WO 2022/194715).
