Clinical integration of software tool VEDO for adaptive and quantitative application of phased array hyperthermia in the head and neck

Figures & data

Figure 1. H&N HTP workflow.

Figure 2. Layout of VEDO. CF SAR is overlaid on the CT-scan, the lighter the colour the higher the CF SAR.

Figure 3. [Case 1] Patient in the HYPER_collar during the test treatment.

Figure 4. [Case 1] Frontal and sagittal view of the patient. For clarity, only segmented bone and CTV are shown. Blue probes (N1,N4) are probes outside the CTV, green probes (T2,T3) are within the CTV and are used to partly base our steering actions on.

Figure 5. [Case 1] Optimisation settings and its properties.

Figure 6. [Case 1] Mean SAR in the CTV based on the recorded applied powers and phases during treatment. The SAR_target values are sampled just before each change of optimisation setting and at the end of treatment.

Figure 7. [Case 2] Patient during the test treatment. The HYPER_collar was originally designed to treat only patients with a tumour in the neck. For patients with a tumour in the head, we use sticky tape for comfort and respiration purposes.

Figure 8. [Case 2] Frontal and sagittal view of the patient. For clarity, only segmented bone and CTV are shown and only the probes within the CTV are labelled. Blue probes are probes outside the CTV, green probes (T1, T2 and T3) are within the CTV and are used to partly base our steering actions on.

Figure 10. [Case 2] Mean SAR in the CTV based on the recorded applied powers and phases during treatment. The SAR_target values are sampled just before each change of optimisation setting and at the end of treatment.
