IMAGING DEVICE, IMAGING SYSTEM, AND METHODS OF IMAGING
First Claim
Patent Images
1. An imaging device, comprising:
- a housing;
a scanning assembly configured to output signals and receive return signals to produce an image when oscillated, wherein the scanning assembly includes an ultrasonic transducer disposed within the housing at an angle with respect to a central axis of the imaging device; and
an angle encoder configured to encode a rotational angle of the scanning assembly.

Abstract
An imaging device, imaging system, and methods of imaging are provided. The imaging device may fit inside a diagnostic or therapeutic assembly, such as a biopsy, drainage, or other type therapy needle assembly. The imaging device may reside inside the diagnostic or therapy assembly as the combined device is advanced to a desired location. Two-dimensional or three-dimensional ultrasonic images may be produced that allow for the accurate placement of the diagnostic or therapy assembly.
