We want to extend our framework to do multi-modal segmentation of multiple tissue types (in our case, stroke lesions, white matter hyperintensity, and normal tissue using T1, FLAIR, DWI, and possibly ADC images). This dataset is particularly challenging due to the low resolution (typically 1mm x 1mm x 7mm) and cropped fields of view in the given images.<br /> &lt;/div&gt;<br /> &lt;div style=&quot;width: 27%; float: left; padding-right: 3%;&quot;&gt;<br /> &lt;h3&gt;Approach, Plan&lt;/h3&gt;<br /> * Identify intensity and shape signatures of different tissue types across images<br /> &lt;/div&gt;<br /> &lt;div style=&quot;width: 27%; float: left; padding-right: 3%;&quot;&gt;<br /> &lt;h3&gt;Progress&lt;/h3&gt;<br /> &lt;/div&gt;<br /> &lt;/div&gt;</div>
