1. A method for treating a patient comprising:
a) placing an ultrasound device in a trachea-bronchial tree of the patient in position to image a targeted tissue;
b) placing a cryoprobe into the targeted tissue;
c) generating an ice ball by cooling the cryoprobe; and
d) while generating the ice ball:
i) rotating the ultrasound device to create multiple 2D image slices of the targeted tissue,
ii) using a computer, combining the multiple 2D image slices to identify a visible surface of the ice ball,
iii) using the computer, generating a 3D model of the ice ball based on the visible surface,
iv) using the computer, generating an isotherm for the 3D model at a selected temperature identified for effective ablation, and
v) using the computer, displaying on a user interface the 3D model of the ice ball and the isotherm.
 
17. A system comprising:
a) a cryoprobe;
b) an ultrasound device;
c) a display;
d) a computer system in communication with the cryoprobe, the ultrasound device, and the display, the computer system having a processor operating under programming, the programming causing the computer system to:
i) receive 2D image slices of targeted tissue in a patient from the ultrasound device as it rotates within the patient, the 2D image slices containing representations of an ice ball as being formed by the cryoprobe,
ii) combine the 2D image slices to identify a visible surface of the ice ball,
iii) generate a 3D model of the ice ball based on the visible surface,
iv) generate an isotherm for the 3D model of the ice ball at a selected temperature identified for effective ablation, and
v) generate on the display a user interface showing the 3D model of the ice ball and the isotherm.
 
27. A computer system in communication with a cryoprobe, ultrasound device, and a display, the computer system comprising:
