## Abstract

Described herein is a method and system for capturing, labeling, measuring and/or comparing images from current and/or previous ultrasound studies using a touch-screen user interface and a display where actions on the touch-screen input data on a captured ultrasound image on the display. Labels and measurements input on the touch-screen user interface are placed in the appropriate location on the captured ultrasound image and on an anatomically matching graphical representation on the touch-screen user interface either or both of which may be used to generate documentation and reports of an ultrasound study.

detecting, from a user, a touch gesture on the user interface;
correlating the touch gesture on the user interface with a stored image manipulation function, wherein each of a plurality of touch gestures is correlated to a different image manipulation function;
applying the image manipulation function associated with the touch gesture to the active ultrasound image and to the graphical representation of the anatomical feature being scanned, wherein information associated with the touch gesture on the user interface manipulates the active ultrasound image;
labeling the graphical representation of the anatomical feature with a location of a lesion or other imaged feature of interest, wherein a label applied to the graphical representation of the anatomical feature on the user interface appears on the active ultrasound image that is being displayed on the display screen; and
wherein subsequent touch gestures on the user interface modify the label of the lesion on the displayed active ultrasound image.

### Claim 2 (depends on 1)

The method of claim 1, further comprising importing the active ultrasound image to a touchpad on the user interface, wherein by tapping on the lesion on the touchpad, a relative depth of the lesion in an image frame of the anatomical feature is captured.

### Claim 3 (depends on 1)

The method of claim 1, wherein image optimization controls on the user interface are used to alter image properties on the first device.

### Claim 4 (depends on 3)

The method of claim 3, wherein the image optimization controls are a focal zone, a time gain compensation, a dynamic range, a frame rate, a Doppler gain, and a field width of the active ultrasound scan.

### Claim 5 (depends on 1)

The method of claim 1, wherein the first device further displays manipulable thumbnails of prior scans of the anatomical feature under examination.

### Claim 6 (depends on 1)

The method of claim 1, wherein the first device further displays thumbnails of captured image frames from the active ultrasound image.

### Claim 7 (depends on 1)

The method of claim 1, wherein an additional annotation is applied to the label applied to the ultrasound image, wherein the additional annotation is one or more of a depth of the lesion or other imaged feature of interest, a number of lesions or other imaged feature of interest, a type of lesion or type of other imaged feature of interest, or a distance of the lesion or other imaged feature of interest from anatomical landmarks.

### Claim 8 (depends on 1)

The method of claim 1, wherein the user interface is used to adjust a time gain compensation of the active ultrasound image.

### Claim 9 (depends on 1)

The method of claim 1, wherein the label applied to the ultrasound image is chosen from a word bank, set of structured labels, or manual entry.

### Claim 10 (depends on 1)

The method of claim 1, further comprising generating a worksheet including information regarding the anatomical feature captured on the active ultrasound image on the first display screen and the graphical representation of the anatomical feature on the user interface.

### Claim 11 (depends on 1)

The method of claim 1, wherein a size of the lesion may be captured through a two finger gesture on a scale on the user interface.

### Claim 12

A method of comparing prior images of an anatomical feature with an active scan, the method comprising:
displaying patient information on a first device that has been inputted through a user interface, wherein the user interface is a touch-screen;
receiving an input of an active scan ultrasound image that includes the anatomical feature being scanned;
displaying the active scan ultrasound image that includes the anatomical feature being scanned on a display screen;
retrieving a series of prior generated ultrasound images of the anatomical feature, wherein the prior generated ultrasound images are displayed adjacent to the active scan;
displaying a graphical representation of the anatomical feature on the user interface, the graphical representation displayed separately from the active scan;
populating the graphical representation of the anatomical feature with labels from a prior generated worksheet;
determining ultrasound images, from the series of prior generated ultrasound images of the anatomical feature, having labels that match labels from the prior generated worksheet;
marking a lesion, or other feature of interest, matching the labels from the prior generated worksheet on the active scan; and
comparing changes in the anatomical feature being scanned with the labels from a single previous ultrasound image, wherein the labels on the graphical representation are amended to indicate the current labels on the active scan.

### Claim 13 (depends on 12)

The method of claim 12, wherein the changes are at least one of additional lesions or other imaged features of interest, change in size, or change in composition.

### Claim 14 (depends on 12)

wherein in response to receiving input from the touch-screen user interface, the second processor sends a signal to a labeling module to input labels and measurements of the target object on both of the ultrasound image displayed on the first display screen and on a graphical representation of the target object displayed on a user interface.

### Claim 17 (depends on 16)
