MRI Coils

MRI Coils that work, superbly, even at 750 MHz

Doty Scientific has developed new rf imaging coils that are truly unique.  New Simple-tune Litz and Litzcage coils provide extraordinary homogeneity and unmatched S/N.   Some have thought that Doty Litz or Litzcage coils are made with litz wire.  That is not the case.  An old meaning of the word litz is woven.  The coils, with the Doty patented insulated crossovers, can be thought of as “woven” coils.

Any of these coils may be dual-frequency (1H/ff ), where ff is a fixed frequency.

Doty imaging coils are supplied in different packaging for several applications.

Links to each type are presented below.
