Comparison of the background echotexture between automated breast ultrasound and handheld breast ultrasound

open access: yesMedicine, 2022
This study aimed to compare the background echotexture (BE) between automated breast ultrasound (ABUS) and handheld breast ultrasound (HHUS) and evaluate the correlation of BE with mammographic (MG) density and background parenchymal enhancement (BPE) on magnetic resonance imaging (MRI).

SHOP: A Deep Learning Based Pipeline for near Real-Time Detection of Small Handheld Objects Present in Blurry Video [PDF]

open access: yes, 2022
While prior works have investigated and developed computational models capable of object detection, models still struggle to reliably interpret images with motion blur and small objects. Moreover, none of these models are specifically designed for handheld object detection. In this work, we present SHOP (Small Handheld Object Pipeline), a pipeline that

A comparison of handheld ultrasound versus traditional ultrasound for acquisition of RUSH views in healthy volunteers [PDF]

open access: yesJACEP Open, 2020
Few studies evaluate the use of handheld ultrasound devices for point-of-care ultrasonography in the emergency department. We hypothesized that image acquisition time and image quality are similar between a handheld device and a traditional device.
