“…Prior research has shown that curved cross-sections are required for analyzing important medical phenomena [31]. We contribute interactions that significantly go beyond existing work on visualization of volumetric datasets, which support only planar cross-cuts [35], only very restricted curvatures [22] or make curvature very hard to control [31].…”

Flexpad is an interactive system that combines a depth camera and a projector to transform sheets of plain paper or foam into flexible, highly deformable, and spatially aware handheld displays. We present a novel approach for tracking deformed surfaces from depth images in real time. It captures deformations in high detail, is very robust to occlusions created by the user's hands and fingers, and does not require any kind of markers or visible texture. As a result, the display is considerably more deformable than in previous work on flexible handheld displays, enabling novel applications that leverage the high expressiveness of detailed deformation. We illustrate these unique capabilities through three application examples: curved cross-cuts in volumetric images, deforming virtual paper characters, and slicing through time in videos. Results from two user studies show that our system is capable of detecting complex deformations and that users are able to perform them quickly and precisely.

“…This creates artifact-free visualizations of the vessel lumen, but not of the surrounding tissue. Saroul et al [34] propose a technique for flattening free-form surfaces of anatomical medical structures that minimizes distortion along a user-specified curve or direction [33]. The surface is spanned between boundary curves, defined by users interactively placing markers within the 3D volume.…”

To analyze the lumen of arbitrarily oriented vessels, Centerline Reformation (CR) has been proposed. Both methods project the vascular structures into 2D image space in order to reconstruct the vessel lumen. In this paper, we propose Curved Surface Reformation (CSR), a technique that computes the vessel lumen fully in 3D. This offers high-quality interactive visualizations of vessel lumina and does not suffer from problems of earlier methods such as ambiguous visibility cues or premature discretization of centerline data. Our method maintains exact visibility information until the final query of the 3D lumina data. We also present feedback from several domain experts.

“…In the present contribution, we extend the parallel planes surface flattening method presented in [16] by providing a multiresolution approach allowing users to interactively modify the center of a region of interest. We also present a new distance-preserving radial planes flattening method where metric distortions (Section 6) grow as a function of the distance from the center of the region of interest.…”

“…However, a planar slice may, for instance, not include a complete longitudinal section of a tubular curved structure such as the aorta. The extraction of curved cross-sections [10], [16] offers a new way of visualizing and inspecting curved anatomic structures. In addition, curved surfaces may easily follow structures made up of several branches such as the aorta with its three outgoing arteries (Fig.…”

Abstract-Curved cross-sections extracted from medical volume images are useful for analyzing nonplanar anatomic structures such as the aorta arch or the pelvis. For visualization and for performing distance measurements, extracted surface sections need to be adequately flattened. We present two different distance preserving surface flattening methods which preserve distances according to a user-specified center of interest and according to user-specified orientations. The first method flattens surface sections by preserving distances along surface curves located within planes having a user specified constant orientation. The second method flattens surfaces along curves located within radial planes crossing the center of interest. We study and compare the properties of the two flattening methods by analyzing their distortion maps. Thanks to a multiresolution approach, we provide surface flattening at interactive rates, allowing users to displace their focus point while visualizing the resulting flattened surface. These distance preserving flattening methods provide new means of inspecting curved cross-sections extracted from medical images.
