Table 1 Semiconductor diode surface measurements at the pulse generator location (patient's right side, contralateral to radiation fields)

From: Spinal cord stimulators and radiotherapy: First case report and practice guidelines

Diode Readings: Right Iliac Fossa

Diode Readings: Left Iliac Fossa

Reading 1: 0.00 cGy

Reading 1: 0.32 cGy ± 0.3 cGy

Reading 2: 0.00 cGy

Reading 2: 0.00 cGy

Reading 3: 1.11 cGy ± 0.32 cGy*

Reading 3: 0.33 cGy ± 0.2 cGy

  1. Readings were also performed on patient's left side (ipsilateral to radiation fields).
  2. *Had the pulse generator received this dose at each fraction this would have equated to a total dose of 27.7 cGy ± 8.1 cGy over a total radiation schedule of 50 Gy in 25 fractions of 2 Gy each (= 0.5% of total dose).
  3. Had the pulse generator received this dose at each fraction, this would have equated to a total dose of 8 cGy ± 7.5 cGy over a total radiation schedule of 50 Gy in 25 fractions of 2 Gy each (= 0.16% of total dose).
