Deep Transcranial Magnetic Stimulation: Improved Coil Design and Assessment of the Induced Fields Using MIDA Model

Table 1

Percentage of volume of each brain tissue where the amplitude of E is greater than 50% of the peak of E (V50) in the cortex for each coil configuration.

Coil	Gray Matter	White Matter	Hippocampus	Nucleus Accumbens	Cerebellum
HFA_R	34.04	32.34	0	0	3.24
HDA_R	33.84	33.07	0.04	1.21	6.20
HFA_L	21.54	20.44	0	0	1.85

(i) HFA_R and HDA_R refer to the percentage of volume of each brain tissue in the right side using the HFA and HDA coils, respectively. (ii) HFA_L and HDA_L refer to the percentage of volume of each brain tissue in the left side using the HFA and HDA coils, respectively. (iii) DC refers to the double-cone coil. (iv) Thalamus, hypothalamus, and amygdala have 0% of tissue volume where the amplitude of E has 50% of the peak of E in the cortex for each coil configuration.
