Abstract
Abstract An ultrasound scanner may display volume renderings of objects in real time. In particular, the system can scan an object at a first time using the ultrasound scanner to provide a first 3D ultrasound dataset that represents the object and of an instrument at a first position. A volume rendering of at least a portion of the object and instrument can be displayed. The first position of the instrument can be adjusted relative to the object based on the displayed volume rendering to provide a second position of the instrument. The object is scanned at a second time using the ultrasound scanner to provide a second 3D ultrasound dataset that represents at least a portion of the object and the instrument at the second position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A method for real time volume rendering of ultrasound data using 2D ultrasound transducer array, the method comprising: scanning an object with a first 2D ultrasound transducer array at a first position to provide a first 3D ultrasound dataset that represents the object; displaying a first volume rendering of at least a portion of the object based on the first 3D ultrasound dataset; and scanning the object and the first 2D ultrasound transducer array using a second 2D ultrasound transducer array at a second position to provide a second 3D ultrasound dataset used to display a second volume rendering that represents the object and the first 2D ultrasound transducer array.
Claim 2
Independent Claim
110 words
A method for real time volume rendering of ultrasound data using 2D ultrasound transducer array, the method comprising: scanning an object with a first 2D ultrasound transducer array at a first position to provide a first 3D ultrasound dataset that represents the object; displaying a first volume rendering of at least a portion of the object based on the first 3D ultrasound dataset; and scanning the object and the first 2D ultrasound transducer array using a second 2D ultrasound transducer array at a second position to provide a second 3D ultrasound dataset used to display a second volume rendering that represents the object and the first 2D ultrasound transducer array.
Claim 3
Dependent Claim
21 words
A method according to claim 1 , wherein the scanning of the first and second 2D ultrasound transducer arrays is interleaved.
Claim 4
Dependent Claim
33 words
A method according to claim 1 further comprising: displaying a rendering of at least a portion of the object and the first 2D ultrasound transducer array based on the second 3D ultrasound dataset.
Claim 5
Dependent Claim
14 words
A method according to claim 3 , wherein the rendering is a volume rendering.
Claim 6
Dependent Claim
23 words
A method according to claim 1 , wherein at least one of the first and second volume renderings comprises colorflow Doppler ultrasound data.
Claim 7
Dependent Claim
23 words
A method according to claim 1 further comprising: guiding an instrument based on at least one of the first and second volume renderings.
Claim 8
Dependent Claim
25 words
A method according to claim 6 wherein the instrument is selected from a list consisting of a biopsy needle, a catheter, and an amniocentesis needle.
Claim 9
Dependent Claim
23 words
A method according to claim 1 further comprising: adjusting a position of at least one of the first and second ultrasound transducer arrays.
Claim 10
Dependent Claim
15 words
A method according to claim 1 further comprising: treating the object with a contrast agent.
Claim 11
Independent Claim
116 words
A system for real time volume rendering of ultrasound data using 2D ultrasound transducer array, the system comprising: means for scanning an object with a first 2D ultrasound transducer array at a first position to provide a first 3D ultrasound dataset that represents the object; means for displaying a first volume rendering of at least a portion of the object based on the first 3D ultrasound dataset; and means for scanning the object and the first 2D ultrasound transducer array using a second 2D ultrasound transducer array at a second position to provide a second 3D ultrasound dataset used to display a second volume rendering that represents the object and the first 2D ultrasound transducer array.
Claim 12
Independent Claim
116 words
A system for real time volume rendering of ultrasound data using 2D ultrasound transducer array, the system comprising: means for scanning an object with a first 2D ultrasound transducer array at a first position to provide a first 3D ultrasound dataset that represents the object; means for displaying a first volume rendering of at least a portion of the object based on the first 3D ultrasound dataset; and means for scanning the object and the first 2D ultrasound transducer array using a second 2D ultrasound transducer array at a second position to provide a second 3D ultrasound dataset used to display a second volume rendering that represents the object and the first 2D ultrasound transducer array.
Claim 13
Dependent Claim
23 words
A system according to claim 10 , wherein the means for scanning interleaves scanning of the first and second 2D ultrasound transducer arrays.
Claim 14
Dependent Claim
35 words
A system according to claim 10 further comprising: means for displaying a rendering of at least a portion of the object and the first 2D ultrasound transducer array based on the second 3D ultrasound dataset.
