Echocardiography is becoming a widely used tool for the diagnosis and treatment of cardiac conditions. Understanding the physics of echocardiography is very essential for its correct application. Doppler is an equally useful modality in echocardiography for the assessment of blood flow. The aim of this article is to outline the basic physics of echocardiography and Doppler and a brief description of various echocardiography machine controls used for the optimization of echocardiography images.
