Sentence examples for spatial compound from inspiring English sources

Compound mode or real-time spatial compound imaging: improves the signal-to-noise ratio and optimises analysis of lesion margins and the internal echostructure of breast masses.

To determine the role of real-time spatial compound imaging in breast ultrasound (US), 38 patients with a total of 50 benign changes (fibroadenomas, cysts, lactiferous duct dilatation) underwent both conventional B-mode US and real-time spatial compound imaging under standardized examination settings.

With significant reader concordance, real-time spatial compound imaging was found to produce speckle reduction with improvement of tissue differentiation, increased conspicuity of low-contrast lesions, enhanced delineation of capsular margins and ducts, and improved depiction of internal architecture of solid lesions, as well as clearer visualization of cystic contents due to clutter reduction.

The examination was carried out using "Spatial Compound Imaging" and "XRES Adaptive Image Processing".

Imaging was performed using an HDI 5000 with spatial compound imaging (SonoCT, Philips Ultrasound, Bothell, WA, USA) with a 7 15 MHz linear probe.

Open image in new window Fig. 7 Longitudinal images of carotid bulb atheroma without (left) and with (right) spatial compounding active.

Spatial compounding aims to improve image quality through signal averaging, but speed-of-sound (SoS) and refraction errors can misalign the component frames and blur the compound image.

Further clinical studies should be performed to compare spatial compounding with and without warping to see which applications would benefit from the small improvement.

Spatial compounding of the large-aperture data drastically improved lesion detectability and produced contrast-to-noise ratio improvements of 83%106%% compared with the large coherent aperture.

Spatial compounding refers to composite images created by insonations from transmitted pulses at multiple different angles to the probe surface (Fig. 1) whilst frequency compounding generates images based on a range of frequencies across the probe bandwidth [4].
