Use of artificial intelligence and deep learning in fetal ultrasound imaging

Ultrasound in Obstetrics and Gynecology, 2022
Deep learning is considered the leading artificial intelligence tool in image analysis in general. Deep‐learning algorithms excel at image recognition, which makes them valuable in medical imaging.

Pseudocoloring of ultrasound images

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Human visual system detects details in coloured images better. Sometimes interpretation of details in gray scale ultrasound images becomes harder. So in this work pseudocoloring of ultrasound images using empirical mode decomposition (EMD) is proposed. EMD doesn't use base function so it has more advantages than Fourier and wavelet transforms.

Image enhancement in ultrasound imaging

2016 24th Signal Processing and Communication Application Conference (SIU), 2016
In this paper, two different methods are suggested in order to provide image enhancement in ultrasonic B-mode imaging. By obtaining RF data from two different phantom used to form B-mode image, their spectral characteristics were observed. Then by forming RF envelope from obtained data, conversion of envelope to color image is provided.

Identification of patients and plaques vulnerable to future coronary events with near-infrared spectroscopy intravascular ultrasound imaging: a prospective, cohort study.

The Lancet, 2019
BACKGROUND Near-infrared spectroscopy (NIRS) intravascular ultrasound imaging can detect lipid-rich plaques (LRPs). LRPs are associated with acute coronary syndromes or myocardial infarction, which can result in revascularisation or cardiac death.

Ultrasound imaging

Journal of Biomedical Engineering, 1988
Modern ultrasonic transducers mainly employ lead zirconate titanate (PZT) but vinylidene fluoride trifluoroethylene copolymer (P (VDF-TrPE)) is becoming more competitive. The static scanner is now largely replaced by mechanical or electronically controlled array real time systems; the speed of scanning is limited by the speed of sound and the ...

Ultrasound Imaging of Nails

Dermatologic Clinics, 2006
The nail apparatus contains tissues of various echogenicities and is thus well suited for ultrasound examination. Furthermore, ultrasonography is widely available and non-invasive and may therefore be used for longitudinal studies of tissues and diseases.

Ultrasound imaging of the scrotum

British Journal of Hospital Medicine, 2008
Although there is a wide variety of scrotal pathology, the clinical features are not always particularly discriminatory. These may include pain, generalized swelling or a focal mass. Ultrasound examination of the testes with a high-frequency linear transducer is the primary (and usually the only) diagnostic modality required for evaluation of the ...

Cardiological Ultrasound Imaging

Current Pharmaceutical Design, 2014
This review paper is intended for the interested outsider of the field of echocardiography and it presents a short introduction into the numerous ultrasound (US) methods and techniques for anatomical and functional diagnosis of the heart. The basic techniques are generally used for some times already, as there are one dimensional (1D) M(otion) mode ...
