  • Question

How to accurately quantify and analyze motion in dynamic cardiovascular image sequences? How to make possible comparison between individuals or longitudinal tracking of an individual ?

  • Objective

To develop or adapt methods for the accurate quantification of motion and strains from dynamic image sequences, and for the registration of images and models to allow comparison between individuals or longitudinal tracking of an individual. Those methods are notably applied for the assessment and analysis of motion and deformation of anatomical structures in dynamic cardiovascular imaging.

  • Method
  1. Motion quantification in image sequences. Our approaches are based on the concept of 2D analytical signal and the associated spatial phase information. A 2D sub-pixel displacement is deduced from phases integrated in local bilinear motion model in [WANG-15a]. In [Gao-16], a method, initially developed for motion tracking in color image sequences, has been adapted by integrating local phase, orientation and magnitude measurements that characterize a 2D monogenic signal. A more conventional differential approach that insures local intensity and shape features invariance to establish the correspondence obtained good results on both cardiac tagged-MR Imaging and Cine, the latter being part of the standard clinical protocol [Wang-19].
  2. Inter and intra-individual data registration. Two strategies are considered: if a parameterized segmentation is available for each subject/sample, data registration is based on a local coordinate system associated to an interpolation scheme [RUMI-17]. On the contrary, a registration between images or models is performed. The locally defined Cardiac function descriptors are mapped to the reference anatomy via this registration, using interpolation for scalar data, eventually completed by a reorientation for vector or tensor data [DUCH-11].
  • Results and illustrations

Figure 1 illustrates motion and radial strain quantification from cine cardiac MRI, used in clinical routine, and tagged MRI of the same patient. Both approaches shows a reduced contractile activity in IL, I and IS sectors where pathology has been identified, with slightly different distributions but with concordant sectorial values. Conventional clinical MRI sequences may therefore be used to assess regional cardiac function.
