Table 2.
Reconstructed prostate dimensions from five individuals and results of anisotropic bubble packing evaluated with bioheat transfer simulation, where VP is the prostate volume, LP is the prostate length, LV2 is the distance from the apex of the prostate to a plane splitting the volume of the prostate into two segments having identical volumes, LS is the optimal insertion depth of cryoprobes, and the defect is presented in comparison with the overall prostate volume.
