		+	This module allows to extract rectangular subvolume from a scalar image, with the subvolume defined by Slicer ROI widget.
		+
		+	You can use this module to crop a DTI or DWI volume.
		+
		+	The cropping functionality of this module is enabled by [[Documentation/4.0/Modules/ResampleScalarVectorDWIVolume \| Resample Scalar/Vector/DWI Volume]] module, which is called internally.

		+	{{documentation/{{documentation/version}}/module-section\|Use Cases}}
		+
		+	{\|
		+	\|
		+	Most frequently used for these scenarios:
		+
		+	* You are trying to segment an object that occupies small portion of the image. Cropping the ROI with that object can simplify your segmentation task and reduce both the memory requirements and processing time.
		+	* You are trying to register two objects that occupy smaller portions of the image. In this scenario, cropping will allow you to focus the processing at the region of interest, and simplify registration initialization.
