Interactive focus + context medical data exploration and editing

Autor: Yeny Yim, Can Kirmizibayrak, James K. Hahn, Dimitre Hristov, Mike Wakid

Publikováno v: Computer Animation and Virtual Worlds. 25:129-141

Volumetric datasets are increasingly used in medical applications. In many of these applications, visualization and interaction is generally performed on cross-sectional two-dimensional 2D views of three-dimensional 3D imaging modalities. Displaying

Interactive Visualization and Analysis of Multimodal Datasets for Surgical Applications

Autor: Yeny Yim, Can Kirmizibayrak, Mike Wakid, James K. Hahn

Publikováno v: Journal of Digital Imaging. 25:792-801

Surgeons use information from multiple sources when making surgical decisions. These include volumetric datasets (such as CT, PET, MRI, and their variants), 2D datasets (such as endoscopic videos), and vector-valued datasets (such as computer simulat

Deformable lung registration between exhale and inhale CT scans using active cells in a combined gradient force approach

Autor: Yeong-Gil Shin, Yeny Yim, Helen Hong

Publikováno v: Medical Physics. 37:4307-4317

Purpose: This article proposes an accurate and fast deformable registration method between end-exhale and end-inhale CT scans that can handle large lung deformations and accelerate the registration process. Methods: The density correction method is a

Correction of segmented lung boundary for inclusion of pleural nodules and pulmonary vessels in chest CT images

Autor: Yeny Yim, Helen Hong

Publikováno v: Computers in Biology and Medicine. 38:845-857

We propose a new curvature-based method for correcting the segmented lung boundary. Our method consists of the following steps. First, the lungs are extracted from chest CT images by the automatic segmentation method. Second, the segmented lung conto

2D-3D registration using gradient-based MI for image guided surgery systems

Autor: Xuanyi Chen, Yeny Yim, James K. Hahn, Steven Bielamowicz, Mike Wakid

Publikováno v: Medical Imaging: Image-Guided Procedures

Registration of preoperative CT data to intra-operative video images is necessary not only to compare the outcome of the vocal fold after surgery with the preplanned shape but also to provide the image guidance for fusion of all imaging modalities. W

Lung ventilation analysis using deformable registration in Xe-enhanced CT images

Autor: Eun-Ah Park, Helen Hong, Jin Mo Goo, Yeny Yim, Julip Jung

Publikováno v: Medical Imaging: Computer-Aided Diagnosis

To analyze lung regional ventilation using two-phase Xe-enhanced CT with wash-in and wash-out periods, we propose an accurate and fast deformable registration and ventilation imaging. To restrict the registration to the lung parenchyma, the left and
