Graphics Processing Unit–Accelerated Nonrigid Registration of MR Images to CT Images During CT-Guided Percutaneous Liver Tumor Ablations
Tokuda, Junichi; Plishker, William; Torabi, Meysam; Olubiyi, Olutayo; Zaki, George; Tatli, Servet; Silverman, Stuart George; Shekher, Raj; Hata, Nobuhiko (Elsevier BV, 2015)Rationale and Objectives: Accuracy and speed are essential for the intraprocedural nonrigid MR-to-CT image registration in the assessment of tumor margins during CT-guided liver tumor ablations. While both accuracy and ... -
Image Registration of Pre-Procedural MRI and Intra-Procedural CT Images to Aid CT-Guided Percutaneous Cryoablation of Renal Tumors
Oguro, Sota; Tuncali, Kemal; Elhawary, Haytham; Morrison, Paul T; Hata, Nobuhiko; Silverman, Stuart George (Springer Nature, 2010)Purpose: To determine whether a non-rigid registration (NRR) technique was more accurate than a rigid registration (RR) technique when fusing pre-procedural contrast-enhanced MR images to unenhanced CT images during CT-guided ... -
Intraoperative Real-Time Querying of White Matter Tracts During Frameless Stereotactic Neuronavigation
Elhawary, Haytham; Liu, Haiying; Patel, Pratik; Norton, Isaiah Hakim; Rigolo, Laura; Papademetris, Xenophon; Hata, Nobuhiko; Golby, Alexandra Jacqueline (Oxford University Press (OUP), 2011)BACKGROUND: Brain surgery faces important challenges when trying to achieve maximum tumor resection while avoiding postoperative neurological deficits. OBJECTIVE: For surgeons to have optimal intraoperative information ... -
Monitoring and visualization techniques for MR-guided laser ablations in an open MR system
Kettenbach, Joachim; Silverman, Stuart George; Hata, Nobuhiko; Kuroda, Kagayaki; Saiviroonporn, Pairash; Zientara, Gary Peter; Morrison, Paul T; Hushek, Stephen G.; Black, Peter McLaren; Kikinis, Ron; Jolesz, Ferenc A. (Wiley-Blackwell, 1998)Our purpose was to develop temperature sensitive MR sequences and image-processing techniques to asses their potential of monitoring interstitial laser therapy (ILT) in brain tumors (n = 3) and liver tumors (n = 7). ILT ... -
Multimodality Non-rigid Image Registration for Planning, Targeting and Monitoring During CT-Guided Percutaneous Liver Tumor Cryoablation
Elhawary, Haytham; Oguro, Sota; Tuncali, Kemal; Morrison, Paul T; Tatli, Servet; Shyn, Paul B.; Silverman, Stuart George; Hata, Nobuhiko (Elsevier BV, 2010)Rationale and Objectives: To develop non-rigid image registration between pre-procedure contrast enhanced MR images and intra-procedure unenhanced CT images, to enhance tumor visualization and localization during CT-guided ... -
Three-Dimensional Computed Tomography for Planning Urologic Surgery
Young, Geoffrey; Silverman, Stuart George; Kettenbach, Joachim; Hata, Nobuhiko; Golland, Polina; Jolesz, Ferenc A.; Loughlin, Kevin Raymond; Kikinis, Ron (Elsevier BV, 1998)The development and marketing of new volumetric computed tomography (CT) scanners in 1990 made it possible to perform three-dimensional (3-D) imaging of the abdomen without respiratory artifacts and with clarity similar ... -
Three-Dimensional Quantitative Assessment of Ablation Margins Based on Registration of Pre- and Post-Procedural MRI and Distance Map
Tani, Soichiro; Tatli, Servet; Hata, Nobuhiko; Garcia-Rojas, Xavier; Olubiyi, Olutayo I.; Silverman, Stuart George; Tokuda, Junichi (Springer Nature, 2016)Purpose: Contrast-enhanced MR images are widely used to confirm the adequacy of ablation margin after liver ablation for early prediction of local recurrence. However, quantitative assessment of the ablation margin by ...
