Analysis of Left Atrial Respiratory and Cardiac Motion for Cardiac Ablation Therapy.

Proceedings of SPIE--the International Society for Optical Engineering

Rettmann ME, Holmes DR, Johnson SB, Lehmann HI, Robb RA, Packer DL.
PMID: 26405370
Proc SPIE Int Soc Opt Eng. 2015 Feb 21;9415. doi: 10.1117/12.2081209.

Cardiac ablation therapy is often guided by models built from preoperative computed tomography (CT) or magnetic resonance imaging (MRI) scans. One of the challenges in guiding a procedure from a preoperative model is properly synching the preoperative models with...

Calibration and Evaluation of a Magnetically Tracked ICE Probe for Guidance of Left Atrial Ablation Therapy.

Proceedings of SPIE--the International Society for Optical Engineering

Linte CA, Rettmann ME, Dilger B, Gunawan MS, Arunachalam SP, Holmes DR, Packer DL, Robb RA.
PMID: 26401065
Proc SPIE Int Soc Opt Eng. 2012 Feb 04;8316. doi: 10.1117/12.912869.

The novel prototype system for advanced visualization for image-guided left atrial ablation therapy developed in our laboratory permits ready integration of multiple imaging modalities, surgical instrument tracking, interventional devices and electro-physiologic data. This technology allows subject-specific procedure planning and...

Toward Standardized Mapping for Left Atrial Analysis and Cardiac Ablation Guidance.

Proceedings of SPIE--the International Society for Optical Engineering

Rettmann ME, Holmes DR, Linte CA, Packer DL, Robb RA.
PMID: 26401067
Proc SPIE Int Soc Opt Eng. 2014 Feb 15;9036. doi: 10.1117/12.2043191.

In catheter-based cardiac ablation, the pulmonary vein ostia are important landmarks for guiding the ablation procedure, and for this reason, have been the focus of many studies quantifying their size, structure, and variability. Analysis of pulmonary vein structure, however,...

Quantitative classification of somatostatin-positive neocortical interneurons identifies three interneuron subtypes.

Frontiers in neural circuits

McGarry LM, Packer AM, Fino E, Nikolenko V, Sippy T, Yuste R.
PMID: 20617186
Front Neural Circuits. 2010 May 14;4:12. doi: 10.3389/fncir.2010.00012. eCollection 2010.

Deciphering the circuitry of the neocortex requires knowledge of its components, making a systematic classification of neocortical neurons necessary. GABAergic interneurons contribute most of the morphological, electrophysiological and molecular diversity of the cortex, yet interneuron subtypes are still not...

Estimation of cell volume and biomass of penicillium chrysogenum using image analysis.
