    abstract = "Multiparametric medical imaging describes approaches that include multiple imaging sequences acquired within the same imaging examination, as opposed to one single imaging sequence or imaging from multiple imaging modalities. Multiparametric imaging in cancer has been shown to be useful for tumor detection and may also depict functional tumor characteristics relevant for clinical phenotypes. However, when confronted with datasets consisting of multiple values per voxel, traditional reading of the imaging series fails to capture complicated patterns. Those patterns of potentially important imaging properties of the parameter space may be critical for the analysis. Standard approaches, such as transfer functions and juxtapositioned visualizations, fail to convey the shape of the multiparametric parameter distribution in sufficient detail. For these reasons, in this paper we present an approach that aims to enable the exploration and analysis of such multiparametric studies using an interactive visual analysis application to remedy the trade-offs between details in the value domain and in spatial resolution. Interactive probing within or across subjects allows for a digital biopsy that is able to uncover multiparametric tissue properties. This may aid in the discrimination between healthy and cancerous tissue, unravel radiomic tissue features that could be linked to targetable pathogenic mechanisms, and potentially highlight metastases that evolved from the primary tumor. We conducted an evaluation with eleven domain experts from the field of gynecological cancer imaging, neurological imaging, and machine learning research to confirm the utility of our approach.",

    is often used in medical diagnostics, especially in prenatal
    screening. Screening the development of the fetus is
    important to assess possible complications early on. State
    of the art approaches involve taking standardized
    measurements to compare them with standardized tables. The
    measurements are taken in a 2D slice view, where precise
    measurements can be difficult to acquire due to the fetal
    pose. Performing the analysis in a 3D view would enable the
    viewer to better discriminate between artefacts and
    representative information. Additionally making data
    comparable between different investigations and patients is
    a goal in medical imaging techniques and is often achieved
    by standardization. With this paper, we introduce a novel
    approach to provide a standardization method for 3D
    ultrasound fetus screenings. Our approach is called “The
    Vitruvian Baby” and incorporates a complete pipeline for
    standardized measuring in fetal 3D ultrasound. The input of
    the method is a 3D ultrasound screening of a fetus and the
    output is the fetus in a standardized T-pose. In this pose,
    taking measurements is easier and comparison of different
    fetuses is possible. In addition to the transformation of
    the 3D ultrasound data, we create an abstract representation
    of the fetus based on accurate measurements. We demonstrate
    the accuracy of our approach on simulated data where the
    ground truth is known.",

    abstract = "Three dimensional (3D) ultrasound is commonly used in prenatal screening, because it provides insight into the shape as well
    as the organs of the fetus. Currently, gynecologists take standardized measurements of the fetus and check for abnormalities by
    analyzing the data in a 2D slice view. The fetal pose may complicate taking precise measurements in such a view. Analyzing the
    data in a 3D view would enable the viewer to better distinguish between artefacts and representative information. Standardization
    in medical imaging techniques aims to make the data comparable between different investigations and patients. It is
    already used in different medical applications for example in magnetic resonance imaging (MRI). With this work, we introduce
    a novel approach to provide a standardization method for 3D ultrasound screenings of fetuses. The approach consists of six
    steps and is called “The Vitruvian Baby”. The input is the data of the 3D ultrasound screening of a fetus and the output shows
    the fetus in a standardized T-pose in which measurements can be made. The precision of standardized measurements compared
    to the gold standard is for the finger to finger span 91,08% and for the head to toe measurement 94,05%.",
