rows and columns can be used instead of the cruciform array described above to provide measurements of the ranges of both angles 26 and 36 referring now to fig4 while the inventors do not wish to be bound by a particular theory it is believed that the cervical tissue 18 is comprised of at least two layers of collagen based tissue including an inner layer 40 a and an outer layer 40 b the inner layer 40 a may contain collagen fibers 42 arranged parallel to the axis 17 that may be measured by the beams 24 produced by the axial transducer array 20 whereas the outer layer 40 b may contain collagen fibers 44 arranged circumferentially about axis 17 to be measured by the beams 38 produced by the circumferential transducer array 34 referring now to fig5 the ultrasound probe 10 may communicate via a flexible cable 46 with an ultrasound machine 48 of the type generally known in the art including for example a digital signal processor 60 receiving ultrasonic data and generating ultrasonic output signals in turn communicating with a standard computer processor 50 executing a program 52 contained in memory 51 to implement the present invention generally the ultrasound machine 48 may also communicate with the display terminal 56 for the outputting of data and a user data entry device 58 such as a keyboard or the like to control operation of the ultrasound machine and to input.
