3D TEE is a technology developed to improve upon the limitations of 2D tomography. With the introduction of the matrix TEE probe, 3D TEE can collect real-time 3D images that provide a comprehensive view of the heart structures, leading to better understanding and decision making during cardiac procedures.
Finally, images of the heart are taken "at stress" to assess wall motion at the peak heart rate. A stress echo assesses wall motion of the heart; it does not, however, create an image of the coronary arteries directly. Ischemia of one or more coronary arteries could cause a wall motion abnormality, which could indicate coronary artery disease.
A 3D ultrasound of a human fetus aged 20 weeks. 3D ultrasound is a medical ultrasound technique, often used in fetal, cardiac, trans-rectal and intra-vascular applications. 3D ultrasound refers specifically to the volume rendering of ultrasound data.
The fundamental concept of electroanatomic mapping systems is to localize catheters within the heart in three dimensional space (a sort of "GPS" within the heart). Building a 3-D model of the heart with real-time visualization permits reduction in fluoroscopy use. In addition to 3-D structure, the voltage and timing of signals at each point of ...
The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
That spurred me to engineer a virtual heart, and now customized 3D simulations are saving lives. ... Patients with heart failure are misdiagnosed at a rate of 16% in hospitals and nearly 70% when ...

Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.
