Clearview ultrasound packages software#
This can retrospectively be adjusted within QCU software as well as retrospectively on numerical QCU data using a mathematical model. 30 MHz BSC catheters connected to a Clearview ® ultrasound console underestimate vessel dimensions. An off-line adjustment formula was derived and applied on previous numerical QCU output data showing relative differences for lumen- and vessel volumes of 0.36 ± 0.51 and 0.13 ± 0.31%.
adjusted measurements of lumen-, vessel- and plaque volumes of −10.1 ± 1.5, −6.7 ± 0.9 and −4.4 ± 0.6%. These showed differences for not adjusted vs. In vivo measurements were performed on 24 randomly selected ICUS studies. Relative differences (unadjusted) of the phantom were respectively: 15.92, 13.01, 10.10 and 12.23%. Evaluation was performed by performing in vitro measurements on a phantom model consisting of four highly accurate steel rings (perfect reflectors) with diameters of 2, 3, 4 and 5 mm. In cooperation with the manufacturer the cause of this underestimation was determined, which is described in this paper, and the QCU software was extended with an adjustment. During evaluation of quantitative coronary ultrasound (QCU) software, it appeared that Boston Scientific Corporation (BSC) 30 MHz catheters connected to a Clearview ® ultrasound console showed smaller dimensions of an in vitro phantom model than expected. It is important that quantitative measurements performed with various ICUS imaging equipment and materials are comparable.
Intracoronary ultrasound (ICUS) is often used in studies evaluating new interventional techniques.
