Figure 4From: Improve definition of titanium tandems in MR-guided high dose rate brachytherapy for cervical cancer using proton density weighted MRIComparison of the segmented image using (a) T2W and (b) PDW images. Image segmentation was based on the histogram thresholding technique. Thresholds were 70 and 90 for T2W and PDW images, respectively. The tandem looked nice and complete in the PDW image but quite fragmental in the T2W image.Back to article page
