1. A medical device system comprising:
a) a catheter having an elongate catheter body including a proximal handle portion and a distal tip portion together forming a catheter assembly, said catheter assembly adapted for use through a bronchoscope working channel providing access to the lung tissue of a patient,
b) at least two electromagnetic sensing coils located within said distal tip portion;
c) a multi-element planar ultrasound transducer array located within said distal tip portion for transmitting and receiving ultrasonic energy in an imaging mode and a acoustic biopsy mode, in the imaging mode said ultrasonic energy having a first frequency and in the acoustic biopsy mode said ultrasonic energy having a second frequency higher than the first frequency, said planar ultrasound transducer array positioned parallel to a longitudinal axis of said catheter body at said distal tip portion;
d) an imaging system coupled to said ultrasound transducer for creating an image of tissue in a first target area extending orthogonally from said catheter body;
e) a backscatter evaluation system for receiving and evaluating acoustic spectral characteristics of tissues located in a second reduced target area, selected from the first target area.
