Ultrasound Image Quality Comparison Between a Handheld Ultrasound Transducer and Mid-Range Ultrasound Machine.

POCUS journal, 2022
Objectives: Not all labor and delivery floors are equipped with ultrasound machines which can serve the needs of both obstetricians and anesthesiologists. This cross-sectional, blinded, randomized observational study compares the image resolution (RES), detail (DET), and quality (IQ) acquired by a handheld ultrasound, the Butterfly iQ, and a mid-range ...

Application and Development of Handheld Ultrasound in the Field of Medicine and Healthcare [PDF]

ADVANCED ULTRASOUND IN DIAGNOSIS AND THERAPY, 2018
With the rapid development of microelectronics, handheld ultrasound devices emerged and have a widespread use in the field of medicine and healthcare. The handheld ultrasound is a modality of medical ultrasonic device that is portable (i.e., carried by hand), easy to operate and in some cases even combine the scanner with the host system.

Handheld ultrasound for portal vein evaluation in pediatric patients. [PDF]

Clin Hemorheol Microcirc
OBJECTIVE: To assess diagnostic capabilities of a modern handheld ultrasound device (HUD) for portal vein (PV) evaluation in pediatric patients and to verify if age, body mass index (BMI) and object depth correlate to imagequality. METHODS: 45 patients (3.9 months– 17.9 years; 10.3 years±5.4) were examined using a HUD and cart-based high-end ultrasound

Training-free image style alignment for self-adapting domain shift on handheld ultrasound devices [PDF]

arXiv
Handheld ultrasound devices face usage limitations due to user inexperience and cannot benefit from supervised deep learning without extensive expert annotations. Moreover, the models trained on standard ultrasound device data are constrained by training data distribution and perform poorly when directly applied to handheld device data.

Efficacies of ultrasound and a handheld dynamometer to predict one-repetition maximum

Journal of Physical Therapy Science, 2019
[Purpose] It is important to accurately measure one-repetition maximum to determine the training load and number of repetitions. However, huge and expensive equipment, such as a torque machine and/or dynamometer, is needed to measure one-repetition maximum.

Three-dimensional clinical handheld photoacoustic/ultrasound scanner

Photoacoustics, 2020
Clinical 2D photoacoustic (PA) imaging can be easily implemented in a traditional ultrasound (US) system. However, 3D PA imaging is still preferable because 2D B-mode PA/US imaging suffers from low reproducibility and high-operator dependency. Here, we demonstrate a compact clinical handheld 3D PA/US scanner using an 1D linear array US transducer ...

Accuracy of lung ultrasound performed with handheld ultrasound device in internal medicine: an observational study. [PDF]

J Ultrasound
Abstract Aims Lung ultrasound (LUS) is increasingly used in Internal Medicine to complement medical examination, documenting pleural and lung conditions. This study aimed to compare the accuracy of handheld ultrasound device (HHUSD) with high-end ultrasound device (HEUSD) in patients with heart failure or pneumonia, also

Improving Lesion Location Reproducibility in Handheld Breast Ultrasound [PDF]

Diagnostics
Interoperator variability in the reproducibility of breast lesions found by handheld ultrasound (HHUS) can significantly interfere with clinical care. This study analyzed the features associated with breast mass position differences during HHUS. The ability of operators to reproduce the position of small masses and the time required to generate ...
