Abstract
A medical system includes an ultrasound probe and a processor. The ultrasound probe is configured for insertion into an organ of a body and includes (i) a two-dimensional (2D) ultrasound transducer array, and (ii) a sensor configured to output signals indicative of a position and orientation of the 2D ultrasound transducer array inside the organ. The processor is configured to (a) using the signals output by the sensor, register multiple ultrasound image sections, acquired by the 2D ultrasound transducer array, with one another, (b) produce a union of the multiple registered ultrasound image sections, to form a rendering of at least a portion of the organ, and (c) present the rendering to a user.

A medical system, comprising:
- an ultrasound probe for insertion into an organ of a body, the ultrasound probe comprising:
- a two-dimensional (2D) ultrasound transducer array;
- and
- a sensor configured to output signals indicative of a position and orientation of the 2D ultrasound transducer array inside the organ;
- and
- a processor, which is configured to:
- using the signals output by the sensor, register multiple ultrasound image sections, acquired by the 2D ultrasound transducer array, with one another;
- produce a union of the multiple registered ultrasound image sections, to form a rendering of at least a portion of the organ;
- and
- present the rendering to a user.
