Improving Lesion Location Reproducibility in Handheld Breast Ultrasound

open access: yesDiagnostics
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 ...

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.

Handheld photoacoustic probe to detect both melanoma depth and volume at high speed in vivo [PDF]

open access: yes, 2015
We applied a linear-array-based photoacoustic probe to detect melanin-containing melanoma tumor depth and volume in nude mice in vivo. This system can image melanomas at five frames per second (fps), which is much faster than our previous handheld single

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Limited Sensitivity of Ultrasound‐Guided Fine‐Needle Aspiration Cytology for Occult Nodal Metastases in Early‐Stage Oral Squamous Cell Carcinoma

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) is commonly used in the diagnostic work‐up of head and neck cancer, but its ability to detect occult lymph node metastases in early‐stage oral squamous cell carcinoma (OSCC) with a clinically negative neck remains unclear.
