## Abstract

An apparatus including a memory (128), a display (122), and a processor (126). The memory is configured to store a protocol definition module (132). The processor is configured to execute the protocol definition module, which causes the processor to display, via the display, an interactive graphical tool (202) that includes a digital representation of an anatomical model with an interactively generated scan field of view superimposed thereover to create a standard scan protocol for execution by an imaging system, wherein the scan field of view identifies anatomy of the subject to scan for the scan protocol.

## Claims

### Claim 1

An apparatus, comprising:
a memory configured to store a protocol definition module;
a display; and
a processor configured to:
execute the protocol definition module, which causes the processor to display, via the display, an interactive graphical tool that includes a digital representation of an anatomical model with an interactively generated scan field of view superimposed thereover to create a scan protocol for execution by an imaging system, wherein the scan field of view identifies anatomy of a subject to scan for the scan protocol;
selects the digital representation to display from a collection of digital representations including at least a first digital representation specific to first anatomy and a second different digital representation specific to second different anatomy, wherein the selected digital representation includes the anatomy of interest;
display an information region in the interactive graphical tool, the information region populated with at least one of an offset, a width, an angularization, a slice thickness, and an image resolution, landmark, or organ to be included or excluded, an external device being used for the scan, CT dose, or other scan specifier;
translate the scan protocol, including the scan field of view, to a pre-scan projection image of a scan plan;
analyze volumetric image data generated by the imaging system to determine whether the volumetric image data adheres to the scan protocol; and
display deviations between the volumetric image data and the scan protocol.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the digital representation further includes a surface model or an anatomical atlas.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the processor creates the scan field of view with at least two planes, each having an orientation and different position over the anatomical model.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the processor positions the scan field of view over the digital representation at a location of the anatomy of interest.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the processor changes a geometry or a location of the scan field of view in response to a geometry or a location change indicated by the input device.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the processor changes the information in the information region in response to an information change indicated by an input device.

### Claim 7

A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
display, via a display, an interactive graphical tool that includes a digital representation of an anatomical model with an interactively generated scan field of view superimposed thereover to create a scan protocol for execution by an imaging system, wherein the scan field of view identifies anatomy of a subject to scan for the scan protocol and the digital representation includes a surface model or an anatomical atlas;
select the digital representation to display from a collection of digital representations;
pre-populate the digital representation with the scan field of view, which is predetermined;
position the scan field of view over the digital representation at a location of the anatomy of interest;
receive a signal as input, and the signal indicates anatomy of interest, and select, based on the anatomy of interest, the digital representation to display from a collection of digital representations, which includes at least a first digital representation specific to first anatomy and a second different digital representation specific to second different anatomy, and selected digital representation includes the anatomy of interest; and
analyze volumetric image data generated by the imaging system to determine whether the volumetric image data adheres to the scan protocol.

### Claim 8 (depends on 7)

The non-transitory computer readable medium claim 7, storing further instructions to create the scan field of view with at least two planes, each having an orientation and different position over the anatomical model.

### Claim 9 (depends on 7)

The non-transitory computer readable medium claim 7, storing further instructions to change a geometry or a location of the scan field of view in response to a geometry or a location change indicated by the input device.

### Claim 10 (depends on 7)

The non-transitory computer readable medium claim 7, storing further instructions to further display an information region in the interactive graphical tool, and populates the information region with at least one of an offset, a width, an angularization, a slice thickness, and an image resolution, landmark or organ to be included or excluded, an external device being used for the scan, CT dose, or other scan specifier.

### Claim 11 (depends on 10)

The non-transitory computer readable medium claim 10, storing further instructions to change the information in the information region in response to an information change indicated by an input device.

### Claim 12 (depends on 7)

The non-transitory computer readable medium claim 7, storing further instructions to store a scan plan module, and execute the scan plan module, wherein executing the scan plan module includes translating the scan protocol, including the scan field of view, to a pre-scan projection image of a scan plan.

### Claim 13 (depends on 7)

The non-transitory computer readable medium claim 7, storing further instructions to display deviations between the volumetric image data and the scan protocol in a dashboard visually presented via the display.

### Claim 14

A computer-implemented method for performing a scan protocol, the method comprising:
displaying an interactive graphical tool that includes a digital representation of an anatomical model with an interactively generated scan field of view superimposed thereover to create a scan protocol for execution by an imaging system, wherein the scan field of view identifies anatomy of a subject to scan for the scan protocol;
receiving an indication of anatomy of interest;
selecting the digital representation to display from a collection of digital representations including at least a first digital representation specific to first anatomy and a second different digital representation specific to second different anatomy, wherein the selected digital representation includes the anatomy of interest;
displaying an information region in the interactive graphical tool, the information region populated with at least one of an offset, a width, an angularization, a slice thickness, and an image resolution, landmark or organ to be included and/or excluded, an external device being used for the scan, CT dose, or other scan specifier;
translating the scan protocol, including the scan field of view, to a pre-scan projection image of a scan plan;
analyzing volumetric image data generated by the imaging system to determine whether the volumetric image data adheres to the scan protocol; and
displaying deviations between the volumetric image data and the scan protocol.
