Introduction
With respect to clinical practice, measuring organ volume is of profound importance in the diagnostic process. Clinicians typically rely on physical exams to estimate these metrics, but this proves to be unreliable as the landmarks and other physical features used in the physical exam can vary from patients to patient and patients' organs themselves are not uniform structures. With the need for better organ volume measurement apparent, ultrasonography was developed and applied to not only visualize a patient's heart in an efficient, non-invasive manner, but to also estimate the heart's volume accurately.
Simpson's rule is a rule which relies on information gathered from these echocardiographic images of various reigons of the heart to estimate volume. This project focuses on evaluating Simpson's rule by building an application in MATLAB for users to select key frames from 2D echocardiographic images in key chambers and regions of the heart and then subsequently measure the diameter for volume calculation.
