A catheterized, three‐component slab phantom has been fabricated for use in mapping specific absorption rate (SAR) distributions from hyperthermia applicators. A planar array of 21 closely spaced catheters, located at one surface of the 1‐cm‐thick slab, can be positioned at depths of 0–7 cm below the phantom surface, in 1‐cm steps, through appropriate placement and orientation of this slab within the three‐slab set. Owing to its modular design, the phantom can be prepared, and also purged of degraded material rapidly and without damage to the catheter tracks.
