Spectral Shift Originating from Non-linear Ultrasonic Wave Propagation and Its Effect on Imaging Resolution
2021, Ultrasound in Medicine and BiologyCitation Excerpt :Also, non-linear wave propagation is inevitable in ultrasound imaging (Duck 2002). The spectral downshift caused by attenuation was introduced as a potential limit in imaging resolution in Harris et al. (1991). Canumalla (1999) calculated the downshift of centre frequency of a pulse and used eqn (1) to estimate the drop in lateral resolution resulting from that.

2014, Journal of Medical Imaging and Radiation SciencesCitation Excerpt :Thus, preantral and early antral (ie, fluid-filled) ovarian follicles and female germ cells (ie, oocytes), are not visualized [15–17]. Ultrasonographic imaging in patients with a large body habitus is often challenging because a lower frequency transducer is required to penetrate deeper into the target organs, resulting in a lesser resolution [18]. In addition, the presence of bowel gas can impede the transmission of ultrasound beams and create artifacts when imaging the ovaries.
Principles of Ultrasound
2011, EndosonographyComputerised analysis of standardised ultrasonographic images to monitor the repair of surgically created core lesions in equine superficial digital flexor tendons following treatment with intratendinous platelet rich plasma or placebo
2011, Veterinary JournalCitation Excerpt :A combination of these creates a 3D block of US information. Each US image is the mixed result of structure-related, single reflections that are generated at the interface of tendon bundles and non-structure-related ‘interference’, which results from multiple interfering echoes generated by structures smaller than the resolution of ultrasonography, such as collagen fibrils (Harris et al., 1991; van Schie and Bakker, 2000). Echoes generated by single reflections on tendon bundles are characterised by consistent echogenicity with respect to intensity and distribution of grey levels over contiguous US images (van Schie and Bakker, 2000).
