a
Steps for calculating material cost (equipment, coil, and maintenance) per session were as follows:
- Cost of core equipment and coil was converted from US dollars into Canadian dollars using the exchange rate of $1 USD = $1.33 CAD (Bank of Canada rate on October 1, 2019). To get the yearly amortization, the cost of acquiring core equipment and coil was divided by number of years of amortization for equipment and coil.
b
Amortization over years (D), according to expert opinion.
c
Yearly cost incurred for iTBS was calculated as the sum of yearly amortization of core equipment, coil, and yearly maintenance.
d
Material cost per session for iTBS was calculated as the sum of yearly amortization of core equipment, coil, and yearly maintenance divided by total sessions of iTBS yearly.
