\section{4D flow MRI}
\begin{frame}
  \frametitle{4D flow MRI}  
 \begin{columns}[c] 
\column{.55\textwidth} % Left column and width
\footnotesize

4D flow MRI has been shown potential in the assesment of blood flow dynamics in heart and large arteries, allowing wide variety of options for visualization and quantification.

\footnotesize

Main limitation for its clinical applicability is the long scan times involved. Therefore, multiple strategies emerged in order to make acquisition faster>
\begin{itemize}
\item Navigator gating
\item modest spatial resolutions $2.5 \times 2.5 \times 2.5 \ mm3$
\item partial data coverage  
\end{itemize}

Typical quality estimators are> SNR, VNR, peak flows/velocities, mass conservation (zero divergence 

We want to introduce a novel measure for quantify the quality of the 4D flow measurements, using the conservation of momentum of the flow.

\end{eqnarray*}

\onslide<2-> And a corrector field which 
\begin{align}
\vec{u}  & \approx   \vec{u}_{meas} + \vec{w} \quad \text{in} \quad \Omega \label{eq:corrector} \\
\nabla \cdot \vec w  & =   0  \quad \text{in}  \quad \Omega \label{eq:correctorDiv} \\

\footnotesize

potential of the new quality parameter> analize real data. use the specificity for label zones with strong disagreedment. Use the field for create new inverse problems which can be used for further accelerations
