Ultrasonography has become a routine diagnostic tool for thyroid nodules due to its high real-time capabilities and low invasiveness. However, thyroid images obtained from current ultrasound tests often have low resolution and are plagued by significant noise interference. Regional differences in medical ...
More specifically, the system and method of the invention aims to create the ultrasonography image for situations where anatomical structures are desired to be localized by the ultrasonography method, such as peripheral nerve block process, and to score the created image....
Initially, logarithm and exponential modifications are applied to improve the brightness of ultrasonography breast images, followed by the use of guided filter techniques to enhance the detail of proliferative ultrasonography images. Saravanan et al. [23] sparse coding estimates is utilised for higher-...
Ultrasonography is a low-cost, informative, safe, reliable, and accessible diagnostic procedure. Several modes of ultrasound scanning are used conventionally. The B-mode (brightness mode) represents ultrasound echo as two dimensional; it is the most commonly used mode in medical diagnostics and study...
Ultrasonography is the best modality for diagnosing breast cancer. To promote preceding treatment and reduce morbidity and mortality, researchers [234] have developed an automated breast cancer diagnosis system with high diagnostic accuracy using DL models. Despite the risk of nerve trauma [235], a ...
(CT), it is the energy of incident photons; in positron emission tomography (PET), it is the photons energy and their detection time; in magnetic resonance imaging (MRI), it is the parameters of a radio-frequency signal emitted by the excited atoms; and in ultrasonography, it is the ...
Non-invasive CROM measurement methods consist of visual inspection, goniometer, cervical range of motion device (CROM device), ultrasonography, and electromagnetic devices. Some of them are not practical for clinical usage due to the requirement of finding anatomical landmarks, long time usage, high...
The aim of this study was to evaluate the safety and accuracy of a new portable ultrasonography-guided high-intensity focused ultrasound (USg-HIFU) system with a 3-dimensional (3D) electronic steering transducer, a simultaneous ablation and imaging module, real-time cavitation monitoring, and 3D ...

by means of ultrasonic radiation is referred to in the art as "ultrasonoscopy". The production by means of ultrasonic radiation of a record which is in, or can be converted to, a viewable form is referred to as "ultrasonography". The instruments for producing ultrasonoscopic images are ...
