Abstract

Examples of the present disclosure describe systems and methods for predicting the reading time and/or reading complexity of a breast image. In aspects, a first set of data relating to the reading time of breast images may be collected from one or more data sources, such as image acquisition workstations, image review workstations, and healthcare professional profile data. The first set of data may be used to train a predictive model to predict/estimate an expected reading time and/or an expected reading complexity for various breast images. Subsequently, a second set of data comprising at least one breast image may be provided as input to the trained predictive model. The trained predictive model may output an estimated reading time and/or reading complexity for the breast image. The output of the trained predictive model may be used to prioritize mammographic studies or optimize the utilization of available time for radiologists.

collecting a second set of data, wherein the second set of data comprises at least second mammographic exam data for a patient, wherein the second mammographic exam data includes breast image data and one or more factors determined according to processing of the breast image data;

applying the second set of data to the trained predictive model;

receiving, from the trained predictive model, an estimated reading time for the second mammographic exam data based on the one or more factors determined according to processing of the breast image data; and

displaying the estimated reading time.

2. The system of claim 1 , wherein the method further comprises:

using the estimated reading time to optimize a workload distribution for a plurality of mammographic exam readers.

5. The system of claim 3 , wherein the image header data is indicative of at least one of: type of study used to collect the mammographic exam data, image resolution of the mammographic exam data, or type of processing used create the mammographic exam data.

6. The system of claim 3 , wherein the user profile data comprises at least one of: an amount of experience of the reader, an age of the reader, or expertise of the reader.

7. The system of claim 3 , wherein the evaluation data comprises at least one of: time of day the evaluation data was collected, type of tools used to collect the evaluation data, usage data for the tools used to collect the evaluation data, and hanging protocol used to generate the evaluation data.

8. The system of claim 1 , wherein the predictive model is at least one of:

a neural network; or

a support vector machine.

9. The system of claim 1 , wherein the predictive model is further trained to output a complexity score, the complexity score representing an estimated complexity of reading the second mammographic exam data.
