Abstract

A method for acquiring an image on an imaging system includes accessing at least first image data from a first imaging system, processing the first image data in accordance with a CAD algorithm, acquiring at least second image data based upon results of the CAD algorithm and processing the second image data in accordance with the CAD algorithm to confirm the results of the CAD algorithm regarding the first image data.

6. A method in accordance with claim 1, wherein the first imaging system is a computed tomography (CT) system.

7. A method in accordance with claim 1, wherein the second image data is acquired on the first imaging system but with a different system configuration than that used for acquiring the first image data.

8. A method for acquiring an image on an imaging system, said method comprising:

receiving an indication of an examination type and an indication of a maximum number of identified features;

accessing first image data from a first imaging system;

processing the first image data in accordance with a CAD algorithm to identify at least one feature via the first image data;

acquiring second image data for each identified feature based upon results of the CAD algorithm;

post-processing, until the maximum number of identified features is reached, the second image data for each identified feature based on the received examination type without operator intervention; and

linking the first image data to the processed second image data to facilitate seamlessly displaying a volume rendering of the first image data and analysis results of the processed second image data in a single display.

9. A method in accordance with claim 8, further comprising displaying the post-processed second image data without operator intervention.

10. A method in accordance with claim 8, wherein the second image data is acquired without operator intervention.

11. A method in accordance with claim 8, further comprising prompting a user to prescribe a scan prescription different than a scan prescription used to generate the first image data based upon results of the CAD algorithm.

12. A method in accordance with claim 11, wherein said prompting comprises prompting the operator to use an imaging modality different than a modality used to generate the first image data.

13. A method in accordance with claim 11, wherein said prompting comprises prompting the operator to use an imaging modality the same as a modality used to generate the first image data but with different parameters.

14. A method in accordance with claim 11, wherein said prompting comprises recommending a scan prescription based upon results of the CAD algorithm.

15. A method in accordance with claim 12, wherein the modality used to generate the first image data is computed tomography (CT).

16. A method for acquiring an image on an imaging system, said method comprising:

prompting a user to input an indication of a maximum number of identified features;

accessing first image data from a first imaging system using a first scan prescription;

processing the first image data in accordance with a CAD algorithm to identify at least one feature via the first image data;

prompting, after the maximum number of identified features is reached, a user to prescribe a second scan prescription different than the first scan prescription based upon results of the CAD algorithm;

acquiring second image data for each identified feature using the second scan prescription; and

linking the first image data to the second image data to facilitate seamlessly displaying a volume rendering of the first image data and analysis results of the second image data in a single display.

17. A method in accordance with claim 16, wherein said prompting, after the maximum number of identified features is reached, a user to prescribe comprises recommending a scan prescription based upon results of the CAD algorithm.
