Operation Manual
ElastoScan Mode
The elasticity of ROI in a 2D image is shown in color. A scanned 2D image is also displayed to indicate the
relative position of ROI and allow the user to change the position.
NOTE:
X
ElastoScan Mode is an option for this product.
X
The probes that can use the ElastoScan Mode are as follows:
L5-13IS (Breast), LF5-12 (Breast), and VR5-9(Urology-Prostate / Gynecology)
Tips!
ElastoScan
This process converts the elastic modulus (ultrasound image data) of a target object, obtained from continuous
ultrasound images, into an elastogram. A lesion's location can be estimated by comparing the differences in
elastic modulus obtained from elastograms. The function of elastography is to determine the difference in
hardness or stiffness between healthy organs and lesions. Palpation has been used to measure stiffness, but this
method is only useful at depths close to the tissue surface. ElastoScan allows the user to identify the existence
of solid masses in tissue, and converts the hardness data into an image by sonically enhancing the palpation.
Elastography shows the spatial distribution of tissue elasticity properties in a region of interest by estimating the
strain before and after tissue distortion caused by external or internal forces. Quantitative elastography is not
provided.
