Abstract

Despite the progress made in ultrasonic imaging, the current examination of vein structures by compression is highly operator-dependent and is a time-consuming clinical routine. Current guidelines for the management of deep vein thrombosis recommend compression ultrasonography follow-up for patients at risk of life-threatening complications (pulmonary embolism, heart attack, or stroke). New methods are needed to allow operator-free monitoring of vein structure at the point of care. This article presents the results of integrated imaging with a tissue compression actuator and automated control of tissue deformation through strain estimation. The data for feedback control of the actuator is calculated from raw ultrasound radio-frequency backscattered signals. The region-averaged strain curve (strain versus time) obtained during the tissue compression cycle serves as input for the actuator. The mounting on the human thigh is made from rigid, pre-shaped shells, which are adjusted to the circumference of the thigh with straps. The actuator facilitates a novel, on-body-mounted, automated, operator-free examination of the human femoral vein.
