Method and apparatus for ultrasound image acquisition |
| 摘要 |
Method for ultrasound image acquisition includes defining a fixed frame of reference, with an origin of coordinates within a transmitter of a tracking system; detecting position and orientation of a probe relative to the frame of reference with a probe sensor of the tracking system coupled to the probe; detecting position and orientation of a body relative to the frame of reference with a reference sensor of the tracking system coupled to the body; calculating position and orientation of the probe with respect to the body; acquiring a set of 2D images constituting a 3D by transmitting an ultrasonic beam into the body and receiving echographic signals with the probe; iterating for a predetermined number of 3D image acquisitions; generating a panoramic 3D image by combining the 2D images based on information of position and orientation of the probe relative to the body for each 2D image acquisition. |

1. A method for ultrasound image acquisition, comprising:
a) defining a fixed frame of reference, an origin of coordinates being set within a transmitter of a tracking system; b) detecting position and orientation of a probe with respect to said fixed frame of reference with a probe sensor of said tracking system coupled to said probe; c) detecting position and orientation of a body to be imaged with respect to said frame of reference with a reference sensor of said tracking system coupled to said body; d) calculating the position and the orientation of said probe with respect to said body; e) acquiring a set of 2D images constituting a 3D image in Doppler mode by transmitting an ultrasonic beam into said body and receiving ecographic signals from said body by said probe; f) iterating steps b) to e) for a predetermined number of 3D image acquisitions; and g) generating a panoramic 3D image combining the 2D images of the acquired 3D images based on information of the position and the orientation of said probe with respect to said body calculated for each 2D image acquisition. |
