Methods and Systems for Estimating a Size of an Object in a Subject with Ultrasound |
| 摘要 |
A system and method for determining, via ultrasound, a size of a concretion in a subject are provided. One or more ultrasound pulses are transmitted into a tissue in the subject, which are then reflected from the tissue and received by the ultrasound transducer. A shadow region obscured by the concretion that does not provide reflected signals is generated, and the width of the shadow region is measured. The width of the object is determined based on the width of the shadow region. |

1. A method for determining a size of an object in a body of a subject comprising:
transmitting an ultrasound pulse to a tissue of the body; receiving signals reflected or scattered from the tissue and the object; generating a shadow region distal to the object; measuring a width of the shadow region; and determining a width of the object based on the width of the shadow region. |
