In vivo MR results with a very thin, ultra-flexible and acoustic transparent head coil showed increase
of the SNR over the body coil by a factor of 7.3 and 7.6 in a brain image with
and without the presence of the transducer, respectively for MRgFUS procedure.
Figure 3. a) Normalized radial acoustic intensity magnitude for 1MHz
(left); 650kHz (center); 220kHz (right) along r-coordinate passing the focal point. b) 2D map of the intensity magnitude showing the effects of the RF coil on the magnitude and the focal point (1MHz (left); 650kHz (center); 220kHz (right). For each frequency, a magnified view of the focal point is displayed in the dotted rectangle. For the frequency of 220kHz, a magnified color bar is displayed. First row : With FUS-Flex coil present at 20 mm ; Second row : at 80 mm ; Third row : reference without coil .

patient positioned inside a focused-ultrasound transducer. b) Photograph of the
FUS-Flex coil.
