## Abstract

A method for generating an ultrasound image, comprising displaying a rendered image of a target from an edge of a full box encompassing the target. An input regarding a selection of a half box may be received from a user. When the half box is not selected, the rendered image may continue to be displayed. When the half box is selected, a new image may be rendered from a reference of the full box, and the rendered image may be displayed.

## Claims

### Claim 1

A method comprising:
generating and displaying a full box volume rendering of a three-dimensional (3D) ultrasound volume defined by a full box encompassing a target in a full box rendering mode;
generating and displaying a slice image at a reference position within the full box through the target;
receiving an instruction to switch to a half box rendering mode, wherein the half box rendering mode comprises:
continuing to display the slice image, wherein the reference position of the slice image is one side of a half box; and
generating and displaying a half box volume rendering of the 3D ultrasound volume of the target defined by the half box.

### Claim 2 (depends on 1)

The method of claim 1, wherein the full box volume rendering depicts a different view position of the target than the slice image.

### Claim 3 (depends on 1)

The method of claim 1, wherein the reference position within the full box is set to a default of a center of the full box.

### Claim 4 (depends on 1)

The method of claim 1, wherein:
the half box and the full box each comprise six sides,
the six sides of the half box comprise the slice image and five other sides, and
the five other sides are in common with five of the six sides of the full box.

### Claim 5 (depends on 1)

The method of claim 1, wherein the half box volume rendering depicts a same view position of the target as the slice image.

### Claim 6 (depends on 1)

The method of claim 1, comprising automatically determining the full box encompassing the target.

### Claim 7 (depends on 1)

The method of claim 1, comprising receiving an input to move the reference position within of the full box.

### Claim 8 (depends on 1)

The method of claim 1, comprising:
automatically detecting an anomaly by determining a difference between at least a portion of the target in the full box volume rendering and at least one stored target image;
setting the reference position to substantially a center of the anomaly within the full box when the reference position is not substantially in the center of the anomaly; and
automatically switching from the full box rendering mode to the half box rendering mode in response to the automatically detecting the anomaly.

### Claim 9 (depends on 1)

The method of claim 1, comprising generating and displaying at least one additional slice image.

### Claim 10

A system comprising:
an input device configured to receive a selection to switch from a full box rendering mode to a half box rendering mode;
a processor configured to:
generate a full volume box rendering of a three-dimensional (3D) ultrasound volume defined by a full box encompassing a target in the full box rendering mode,
generate a slice image at a reference position within the full box through the target in the full box rendering mode, and
generate a half box volume rendering of the 3D ultrasound volume of the target defined by a half box in the half box rendering mode, wherein the reference position of the slice image is one side of the half box; and
a display configured to:
display the full box volume rendering and the slice image in the full box rendering mode, and
display the half box volume rendering and the slice image in the half box rendering mode.

### Claim 11 (depends on 10)

The system of claim 10, wherein the full box volume rendering depicts a different view position of the target than the slice image.

### Claim 12 (depends on 10)

The system of claim 10, wherein the reference position of the full box is set to a default of a center of the full box.

### Claim 13 (depends on 10)

The system of claim 10, wherein the processor is configured to:
automatically detect an anomaly by determining a difference between at least a portion of the target in the full box volume rendering and at least one stored target image,
set the reference position to substantially a center of the anomaly within the full box when the reference position is not substantially in the center of the anomaly, and
automatically switch from the bull box rendering mode to the half box rendering mode in response to the automatically detect the anomaly.

### Claim 14 (depends on 10)

The system of claim 10, wherein the half box volume rendering depicts a same view position of the target as the slice image.

### Claim 15 (depends on 10)

The system of claim 10, wherein the processor is configured to automatically determine the full box encompassing the target.

### Claim 16 (depends on 10)

The system of claim 10, wherein the input device is configured to receive an input to move the reference position within the full box.

### Claim 17

A non-transitory computer readable medium having stored thereon, a computer program having at least one code section, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
generating and displaying a full box volume rendering of a three-dimensional (3D) ultrasound volume defined by a full box encompassing a target in a full box rendering mode;
generating and displaying a slice image at a reference position within the full box through the target;
receiving an instruction to switch to a half box rendering mode, wherein the half box rendering mode comprises:
continuing to display the slice image, wherein the reference position of the slice image is one side of a half box; and
generating and displaying a half box volume rendering of the 3D ultrasound volume of the target defined by the half box.

### Claim 18 (depends on 17)

The non-transitory computer readable medium of claim 17, wherein the full box volume rendering depicts a different view position of the target than the slice image.

### Claim 19 (depends on 17)

The non-transitory computer readable medium of claim 17, wherein the reference position within the full box is set to a default of a center of the full box.

### Claim 20 (depends on 17)

The non-transitory computer readable medium of claim 17, wherein the half box volume rendering depicts a same view position of the target as the slice image.
