Magnetic resonance acoustic radiation force imaging. SMR-ARFI in an ex vivo kidney sample. a T2-weighted image showing the sample, and the transducer. An acoustically absorbent phantom was placed on top of the sample to hold it in place. B and C Maps of the displacement during two sonications applied before b and after c focused ultrasound thermal ablation. D MR temperature image acquired during ablation. E Plots showing displacement in the focal plane before and after ablation. The average of three lines is shown in this plot. The normalized spatial distribution of the temperature rise at peak temperature rise during ablation is also shown. The peak temperature rise achieved during this sonication was 31 °C.

Population of Diffusion Tensor MR Images. Segmentation results from three subjects’ left thalamic hemispheres are shown. Colors indicate the mean diffusion orientation in each cluster. (A) Segmentations obtained using k-means have an ellipsoidal bias and they do not correspond well between subjects. (B) Segmentations obtained using CC with no prior information are consistent among subjects. (C) Segmentation using CC with prior information are both consistent among subjects and match well with the expert segmentations. (D) Expert labeled thalami are shown. Read more here


A mathematical framework for incorporating anatomical knowledge in DT-MRI analysis. Visualization of some of ROIs outlined by the atlas. These ROIs correspond to the major anatomical fiber tracts. Read more here


Spatial distribution of white-matter hyperintensities in Alzheimer disease, cerebral amyloid angiopathy, and healthy aging. SPECT atlas of cerebral white matter perfusion constructed from 47 healthy adult volunteers illustrating significant inhomogeneity. Perfusion values are indicated by the colorbar, in which red indicates higher perfusion. Read more here


Slicer3 version of CT based abdominal atlas released. The Surgical Planning Laboratory at Brigham and Women's Hospital, Harvard Medical School, developed the SPL Abdominal Atlas. The atlas was derived from a computed tomography (CT) scan, using semi-automated image segmentation and three-dimensional reconstruction techniques. Read more here


Automated segmentation of brain tumors. The 2001 paper by Kaus et al. reported about automated segmentation of brain tumors. The data that was used for this research is now made available. This will allow other scientists to compare their algorithms with ours. Read more here


An accessible, hands-on tutorial system for image-guided therapy and medical robotics using a robot and open-source software. This paper describes a new open-source tutorial for image-guided therapy (IGT) and medical robotics that is both accessible and hands-on using the LEGO Mindstorms NXT (a commercially available robotics kit) and 3D Slicer (an open-source application for medical image processing).
