Using Reconstructed IVUS Images for Coronary Plaque Classification

Abstract: Coronary plaque rupture is one of the principal causes of sudden death in western societies. Reliable diagnostic of the different plaque types are of great interest for the medical community the predicting their evolution and applying an effective treatment. To achieve this, a tissue classification must be performed. Intravascular Ultrasound (IVUS) represents a technique to explore the vessel walls and to observe its histological properties. In this paper, a method to reconstruct IVUS images from the raw Radio… Show more

“…The description of tissue properties is obtained extracting a set of textural features from the image in polar coordinates. This set is obtained from previous studies on lumen segmentation (Ciompi et al, 2009) and plaque characterization in IVUS (Ciompi et al, 2010a;Caballero et al, 2007).…”

“…• Band pass filtering: a Butterworth Band Pass (BP) filter of order 10 and frequencies f L = 20 MHz, f H = 60 MHz • Envelope recovering: computed as the absolute value of the Hilbert transform of the RF signal • Logarithmic compression: it improves the visualization of areas with a low signal intensity, as in [24,28] • Digital Development Process: a non-linear radial adjustment of the gain and edge-emphasis process to enhance the tissue visualization [9,24] At the end of this process, a polar representation of an IVUS image is obtained (Fig. 3a).…”

“…Then, we extract a wide set of textural features by applying texture descriptors to the obtained image. As in [9] we apply a bank of 16 Gabor filters [29] and three configurations of Local Binary Patterns [30], thus obtaining 19 textural features. Furthermore, due to the high echo-reflectivity property of calcified tissue, we decided to add two features, called (1) shadow and (2) relative shadow, computed by (1) accumulating the mean grey level value along each radial direction and by (2) multiplying the obtained value by the radial depth in each considered position.…”
