Computing Strain Elastograms of Skin Using an Optical Flow Based Method
نویسندگان
چکیده
Background: Most elastography studies focus on detecting property anomalies of internal organs such as heart and kidney [1]. We report a preliminary work on computing strain elastograms of human skin. A camcorder was used to capture the deformation of skin surface in a video sequence, upon which tracking was performed with an optical flow method to generate a dense motion field [2]. A strain elastogram is then obtained by convolving the motion field with a gradient filter. Potential applications of the proposed method include skin cancer detection, burn scar assessment and facial surgery simulation [3].

Comparative evaluation of strain-based and model-based modulus elastography.
Elastography based on strain imaging currently endures mechanical artefacts and limited contrast transfer efficiency. Solving the inverse elasticity problem (IEP) should obviate these difficulties; however, this approach to elastography is often fraught with problems because of the ill-posed nature of the IEP. The aim of the present study was to determine how the quality of modulus elastograms ...
متن کاملUltrasonic elastography using sector scan imaging and a radial compression.
Elastography is an imaging technique based on strain estimation in soft tissues under quasi-static compression. The stress is usually created by a compression plate, and the target is imaged by an ultrasonic linear array. This configuration is used for breast elastography, and has been investigated both theoretically and experimentally. Phenomena such as strain decay with tissue depth and strai...

Tissue stiffness is generally known to be associated with pathologic changes. Ultrasound (US) elastography, on the other hand, is capable of imaging tissue strain, which may or may not be well-correlated with tissue stiffness. Hence, a quantitative comparison between the elastographic tissue strain images and the corresponding tissue modulus images needed to be performed to evaluate the usefuln...

Optical strain maps calculated during a facial expression describe a bio-mechanical property of facial skin tissue, and are derived from the non-rigid motion incurred during facial expressions. In this paper, we propose a method for accurately estimating and modeling the three-dimensional strain impacted onto the face using standard optical flow techniques and a dynamic depth map.
