Assessment of the motion of the temporomandibular joint
is of interest for a variety of pathologies. The dynamic
visualization of the TMJ under realistic mastication is
still limited by the poor spatiotemporal resolution. In
this contribution we combine the advantages of
self-gating and adaptive averaging by using contour
fitting in the correlation matrix (CoFi-CoMa) to
increase the achievable temporal resolution and SNR.
Moving images of the TMJ at this fast opening / closing
cycle rate in combination with the achieved high
temporal resolution and high SNR have not been shown
before.
