Final answer:
Muti-planar reconstructions are performed on raw data in medical imaging to generate images in different planes or orientations from the original data.
Step-by-step explanation:
Muti-planar reconstructions are performed on raw data. This technique is commonly used in medical imaging, such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI), to generate images in different planes or orientations from the original data. By reconstructing the raw data in multiple planes, healthcare professionals can obtain a more comprehensive view of the scanned area, which aids in diagnosis and treatment planning.
