| Abstract [eng] |
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 lifethreatening 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, preshaped 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. |
