Abstract
Ultrasound elastography is an imaging technique used to image tissue elasticity and is often referred to as virtual palpation. This article reviews the principles of ultrasound elastography and its clinical applications. Originally, Elastography is a non-invasive method in which stiffness or strain images of soft tissue are used to detect or classify tumors by comparing pre- and post compression images. The tissue is compressed and relaxed using external force and pre- and post compression ultrasound images are acquired. This method is easy to use and also cheap as it does not require any additional hardware/circuits. While elastography can also be performed with MRI and CT, low cost and portability of ultrasound equipment makes it better choice for widespread application of elastography techniques in the medical imaging field. However, new techniques have been developed that use different excitation methods such as external vibration or acoustic radiation force to compress the tissues. Clinical use of elastography is increasing, with various applications including lesion detection and classification, treatment monitoring, fibrosis staging, vascular imaging and musculoskeletal applications. For successful clinical use in cancer diagnosis and monitoring the method should be robust to sources of decorrelation between ultrasound images.
Keywords- Elastography, Ultrasound, tumor, strain images, elastogram, RF data.
