“…This technique is effective for convex structures but may lead to distortions in irregularly shaped aneurysms where the center of mass is external to the surface. In heart disease research, particularly for analyzing left ventricular function, the Cardiac Bull's Eye Plot (BEP) has been popular [KHB*06,OKG*06,KMP*15]. This abstract 2D representation simplifies complex cardiac data by projecting the myocardium into 17 circularly arranged regions.…”

Exploratory analysis of scalar fields on surface meshes presents significant challenges in identifying and visualizing important regions, particularly on the surface's backside. Previous visualization methods achieved only a limited visibility of significant features, i.e., regions with high or low scalar values, during interactive exploration. In response to this, we propose a novel technique, InverseVis, which leverages curved sphere tracing and uses the otherwise unused space to enhance visibility. Our approach combines direct and indirect rendering, allowing camera rays to wrap around the surface and reveal information from the backside. To achieve this, we formulate an energy term that guides the image synthesis in previously unused space, highlighting the most important regions of the backside. By quantifying the amount of visible important features, we optimize the camera position to maximize the visibility of the scalar field on both the front and backsides. InverseVis is benchmarked against state‐of‐the‐art methods and a derived technique, showcasing its effectiveness in revealing essential features and outperforming existing approaches.

A Survey of Medical Visualization through the Lens of Metaphors

We provide an overview of metaphors that were used in medical visualization and related user interfaces. Metaphors are employed to translate concepts from a source domain to a target domain. The survey is grounded in a discussion of metaphor-based design involving the identification and reflection of candidate metaphors. We consider metaphors that have a source domain in one branch of medicine, e.g., the virtual mirror that solves problems in orthopedics and laparoscopy with a mirror that resembles the dentist's mirror. Other metaphors employ the physical world as the source domain, such as crepuscular rays that inspire a solution for access planning in tumor therapy. Aviation is another source of inspiration, leading to metaphors, such as surgical cockpits, surgical control towers, and surgery navigation according to an instrument flight. This paper should raise awareness for metaphors and their potential to focus the design of computer-assisted systems on useful features and a positive user experience. Limitations and potential drawbacks of a metaphor-based user interface design for medical applications are also considered.

“…Mesh parameterizations are used for mapping different vascular structures comprising: specific structures like aneurysm surfaces [GSK * 12, MVB * 17, MVPL18, MGB * 19, MVG * 21], stenosis predilection sites [AS03, AS04, CUS * 17, CES * 08, CLC13, CUSF13, CCC16, CCLC17, CCR20, ZSC21], or heart valves and cavities [EEL * 19, KMJ * 14, LER * 20, MKH * 12, NGBD * 19, PBI * 17, RPM * 19, WTGZ * 17] but also arbitrary vessel tree walls [ERM * 21, ZHT * 02a, ZHT02b, ZHT03, ZHT05]. For techniques based on surface projections , the properties are projected onto a parametric structure like a cylinder, disk, or sphere [BSR * 14,KHB * 06,NGB * 09,OKG * 06,SCK * 16,TBB * 07]. The approach is similar to mesh parameterization, however, the topology is not retained, which means bijectivity cannot be ensured.…”

“…Within the plot segments, a perfusion parameter is color‐coded to provide an overview about myocardial perfusion which simplifies the detection of regions with poor blood supply. Oeltze et al [OKG * 06] extend the BEP‐based visualization of myocardial perfusion data. For the simultaneous representation of rest and stress perfusion, the segments of the plot are divided in two, resulting in 34 segments, with 17 each color‐encoding rest and stress perfusion, respectively, see Figure 9.…”

Input Graph LayoutFigure 1: We describe the creation of a vessel map as a three-step process: the layout of the map must be derived, the geometry or spatiality of the data must be mapped, and the data attributes must be mapped. We differentiate between image volume maps, flow volume maps, vessel wall maps, and vessel network maps depending on the primary data structure the map-like visualization is based on.
