\title{Mobile C-arm Deformation and its implication on Stereoscopic Localization}
\author{Maximilian Neidhardt, Omer Rajput*, Daniel Drömann and Alexander Schlaefer}
\begin{document}
\maketitle
\block{Medical background}{
\begin{multicols*}{3}
Accurate localization in minimally invasive procedures is challenging, particularly in the presence of non-ideal imaging systems. Mobile C-arms present a widely guidance, e.g., during bronchoscopy. However, the localization accuracy is susceptible to non-idealities like gravitational deformation of the C-arm gantry. We present a simulation study of the effects of the deformation on the external tracking of the gantry pose and the marker based pose estimation from within the X-ray images.
\end{multicols*}
}
\block{Methods and materials}{
\begin{multicols*}{3}
\textbf{C-arm pose estimation:} We compare two approaches for the C-arm pose estimation. First, the C-arm gantry is tracked externally using an optical camera. Second, a stationary rigid marker system of a known geometry and the corresponding X-ray images are system relative to the C-arm by the POSIT algorithm.
\textbf{Target Localization:} After the relative transformation between two poses of the C-arm gantry is known, the target (e.g., a tool position) can be reconstructed in 3D by using the two X-ray images acquired at these two poses. For an ideal system, it is straight-forward to estimate the target in 3D space by triangulation (Fig. 1a). However in the presence of non-idealities, the selection of reference frame for triangulation becomes crucial.
\textbf{Deformation analysis:} For our analysis, we use a C-arm model based on a clinical system (BV Endura, Philips Medical Systems - Fig. 1b). The deformation of the model due to the gravitational force is analyzed by using the finite element method (FEM).

但是自定义块标题样式比较麻烦。我想问一下是否有办法知道块标题文本的宽度，以便从块标题文本末尾开始创建一行。
答案1
另一个选择是重新定义\block宏以包含更粗的版本\hrulefill（参见\hrulefill 的厚度是多少) 位于块标题之后。代码变得相当长，因为该定义相当长，因此您可以考虑将其放在单独的文件中。
的定义\block是从 复制而来tikzposter.cls，仅做了两处更改：从\newcommand到\renewcommand，并且增加了\thickrulefill。
请注意，我添加了demo类选项，因为我没有您的图像，并且注释了\setmainfont和\setsansfont，因为我没有安装 Gill 字体。还请注意，您不应该使用加载fontenc，fontspec所以我删除了前者。
