Figures & data

Figure 1. Two typical thermal maps provided by RHyThM: (a) A thermal map, as accepted for the study, with no shift in transition between in- and out side the body during whole of the treatment session. (b) A thermal map with shift in transition between in- and outside the body, not accepted. The graph shows that the start position of the steep temperature decay moves over time towards the left.

Figure 2. Intra-luminal temperature measurement. TC (tumour contact) is defined as close contact of the thermometry catheter with tumour; TI (tumour indicative) is defined as the position of the thermometry catheter ventral or dorsal of the tumour in the same transverse plane as the tumour but not in contact.
