Visualization of CT and MR images of the phantom.

<p>Left: 3D volume rendering of the CT data with low-level threshold to remove the “parenchyma” (candle gel component). Middle column: Orthogonal slices through the CT volume at the position indicated by the yellow cross in the 3D rendering, axial, coronal and sagittal slices (top to bottom). Right column: Corresponding MR slices from the MR volume data at the same position in the phantom. No thresholding has been applied to the MR data.</p

Orthogonal slicing through a 3D ultrasound volume and the MR volume data.

<p>From top to bottom: axial, coronal and sagittal slices. The tumor model has a silicone string going into it, representing a portal vein, as can be seen in the coronal slice in both ultrasound and MR.</p

The original MR, CT, and US images from the phantom and patients along with the cropped regions.

Manufacturing multimodal phantom.

<p>Left: step 19 of the protocol; Middle: step 22 of the protocol; Right: the end result of the protocol – multimodal phantom mimicking liver tissue.</p
