System and method for automated longitudinal review

A system for automatically performing a longitudinal review of medical imaging data, comprising:

• one or more memories encoding processor-executable routines;
• and
• one or more processors configured to access the one or more memories and to execute the processor-executable routines, wherein the routines, when executed by the one or more processors, cause the one or more processors to:
• obtain, at a computing device, a first image volume acquired of a subject with a medical imaging system of an imaging modality;
• obtain, at the computing device, a second image volume acquired of the subject with the medical imaging system or another medical imaging system of the imaging modality or a different imaging modality, wherein the first image volume was acquired at an earlier time point than the second image volume;
• automatically align, via the computing device, the second image volume to the first image volume to generate aligned image volumes, wherein the first image volume is obtained from a picture archiving and communication system (PACS) and the computing device comprises an operator console of the medical imaging system or the another medical imaging system, wherein automatically aligning the second image volume and the first image volume comprises performing registration and transformation between the first image volume and the second image volume;
• orient the aligned image volumes to a standard anatomical plane and a matched plane corresponding to the orientation of the first image volume;
• generate one or more difference images based on the aligned image volumes;
• overlay a color image derived from one of the image volumes onto the other image volume or the difference image;
• transfer the aligned image volumes, the difference image, and the overlay to the PACS;
• and
• enable toggle functionality between the aligned image volumes, the difference image, and the overlay via an input device of the computing device for viewing on a display of the computing device.

A non-transitory computer-readable medium, the computer-readable medium comprising processor-executable code that when executed by one or more processors, causes the one or more processors to:

• obtain, at a computing device, a first image volume acquired of a subject with a medical imaging system of an imaging modality;
• obtain, at the computing device, a second image volume acquired of the subject with the medical imaging system or another medical imaging system of the imaging modality or a different imaging modality, wherein the first image volume was acquired at an earlier time point than the second image volume;
• and
• automatically align, via the computing device, the second image volume to the first image volume to generate aligned image volumes, wherein the first image volume is obtained from an operator console of the medical imaging system or the another medical imaging system, the computing device is the operator console, and wherein automatically aligned the second image volume and the first image volume comprises performing registration, transformation, and image overlaying between the first image volume and the second image volume;
• orient the aligned image volumes to a standard anatomical plane and a matched plane corresponding to the orientation of the first image volume;
• generate one or more difference images based on the aligned image volumes;
• overlay a color image derived from one of the image volumes onto the other image volume or the difference image;
• transfer the aligned image volumes, the difference image, and the overlay to the PACS;
• and
• enable toggle functionality between the aligned image volumes, the difference image, and the overlay via an input device of the computing device for viewing on a display of the computing device.
