{{documentation/{{documentation/version}}/module-section|Module Description}}
{{documentation/modulename}} module allows to output a filtered transform node based on an tracker input (transform node). Tracking sensors are particularly usefull to track surgical tools, robots, patient motion, etc... . However, data imported in 3D Slicer from these devices are often noisy. To reduce the noise and smoothly control objects, such as 3D Slicer camera, the {{documentation/modulename}} module will apply a low-pass filter on input data. The cut-off frequency (i.e. the smoothing parameter) is adjustable by the user.
+
The {{documentation/modulename}} is designed to segment tumors from DCE-MRI datasets which include 1 pre-contrast image and 2-4 post-contrast images at different time points. {{documentation/modulename}} uses blackbox methods to calculate the wash-in and wash-out slopes of the contrast dye based on voxel intensity values. The segmentation output is a Label Map with red, yellow, and blue colors respectively identifying washout, plateau, and persistent voxels.
It is important to notice that filters induce delay, and the smoother the motion is, the bigger the delay between the raw data and the filtered position will be. -->

The {{documentation/modulename}} module could be used in any situation requiring stable tracking data and not requiring a "real-time" information. Indeed, applying a filter on raw data will induce a delay (depending on choosen parameters) on the filtered position/orientation.

Module Description

The OpenCAD is designed to segment tumors from DCE-MRI datasets which include 1 pre-contrast image and 2-4 post-contrast images at different time points. OpenCAD uses blackbox methods to calculate the wash-in and wash-out slopes of the contrast dye based on voxel intensity values. The segmentation output is a Label Map with red, yellow, and blue colors respectively identifying washout, plateau, and persistent voxels.
