Surface transmit arrays provide great advantages for
ultra-high field imaging in terms of efficiency. More
recently, dipole antennas have improved their
performance considerably. However, their rigid structure
does not always allow them to adapt to the body
curvature. This work presents a dipole antenna prostate
array that consists of foam and flexible PCB. The
structure always adapts well to the shape of the
subject. Matching was shown to be acceptable for three
different subjects while coupling between elements is
minimal. Imaging performance was characterized by a T2w
TSE prostate image.
