To determine the elastic modulus of biologic tissue, a sequence of elasticity images and a sequence of B-mode ultrasound images are acquired simultaneously. Then, at least one sub-sequence of the B-mode ultrasound images representing a resting state is generated from said sequence of B-mode ultrasound images. Based on the sub-sequence of the B-mode ultrasound images, a subsequence of the elasticity images is generated by selecting and/or modifying those elasticity images. Finally, the elastic modulus is determined based on the sub-sequence of the elasticity images. Also disclosed are a method for determining changes of the elastic modulus of a tissue, a method of identifying biological tissue based on the determined elastic modulus and a device for determining the elastic modulus of a biological tissue.
Method for determining the elastic modulus of a region of interest in biologic tissue, to obtain stiffness information about the region of interest, comprising the steps of:
Method for determining changes of the elasticity of a region of interest in biological tissue, wherein a differential elasticity image is generated by subtracting the acquired value of each pixel of a first enhanced elasticity image of a region of interest with the corresponding acquired value of each pixel of at least a second enhanced elasticity image of the same region of interest acquired at a different time point.
Device for determining the elastic modulus of a region of interest in biological tissue, comprising:
