1. A system for providing visual feedback of a bone having an artificial implant installed therein and a lesion between the bone and the artificial implant, comprising:
- a hand-held ultrasound device adapted to transmit a signal though the artificial implant into the bone, receive reflected signals indicative of inconsistency in the bone of the lesion and produce a corresponding output signal;
a processor in communication with said hand-held ultrasound device and adapted to receive said output signal, said processor configured to formulate a 3-D model of the lesion based on the output signal, said processor providing a display signal; and
a display device in communication with said processor and responsive to said display signal to display at least one view of the 3-D model of the lesion.

Abstract
Apparatus and methods for assessing tissue characteristics such as the dimensions and volume of an osteolytic lesion are disclosed. The apparatus may utilize ultrasound to provide visual and volumetric feedback related to a lesion or other tissue. Further the apparatus may be utilized to determine whether the lesion has been completely removed and filled with the appropriate amount of graft material.

8. A method of assessing a bone having an artificial implant installed therein and a lesion between the bone and the artificial implant, comprising:
-
providing an ultrasound device, a processor, and a display device; activating the ultrasound device through the artificial implant adjacent the lesion; sensing the signals reflected from the bone and lesion; processing the reflected signals to generate at least a portion of a 3-D model of the lesion; and displaying at least a portion of the 3-D model of the lesion. - View Dependent Claims (9, 10, 11, 12, 13, 21, 22, 23, 24, 25, 26, 27)
