1. An ultrasound imaging system, comprising:
- an ultrasound unit configured to ultrasonically scan at least one plane within a region of interest in a subject and generate imaging information from the scan;
an inertial reference unit configured to detect relative position of the ultrasound unit, during at least one scan of at least one plane; and
a processing unit configured to receive the imaging information and the detected corresponding relative positions and,based on the received imaging information and relative position, operable to generate at least one image of the region of interest.

Abstract
Systems and methods for ultrasound imaging using an inertial reference unit are disclosed. In one embodiment, an ultrasound imaging system includes an ultrasound unit configured to ultrasonically scan at least one plane within a region of interest in a subject and generate imaging information from the scan. An inertial reference unit is provided that detects relative positions of the ultrasound unit as the ultrasound unit scans a plurality of plane. A processing unit is configured to receive the imaging information and the corresponding detected position and is operable to generate images of the region of interest.

11. A method of imaging a bodily portion in a subject, comprising:
-
ultrasonically scanning a first selected plane in the subject using an ultrasound scanning device to generate a first planar ultrasound data set; determining a position of the first selected plane by accessing an inertial reference unit coupled to the ultrasound scanning device; ultrasonically scanning a second selected plane in the subject to generate a second planar ultrasound data set; determining a position of the second selected plane; and processing the first data set and the position of the first selected plane and the second data set and the position of the second selected plane to generate a three-dimensional image of the bodily portion. - View Dependent Claims (12, 13, 14, 15)

16. A ultrasound system configured for hand held operation, comprising:
-
an ultrasound transceiver having an outwardly extending handle suitably configured to permit a user to manipulate the transceiver relative to a subject; an inertial reference unit coupled to the transceiver that is operable to determine selected positions of the transceiver as it is moved; and a processing unit coupled to the ultrasound transceiver and the inertial reference unit that is configured to process ultrasound data acquired from the subject and to process positional data and generate an ultrasound image therefrom. - View Dependent Claims (17, 18, 19, 20, 21)
