Authoritative definitions of ultrasound protocols, anatomical landmarks, pathology findings, and technical terminology for point-of-care practice across medical specialties.
B-lines
In lung ultrasound, B-lines are vertical, hyperechoic artifacts that originate from the pleural line and extend to the bottom of
Bandwidth
In physics, particularly within medical and ultrasound imaging, bandwidth refers to the range of frequencies present in an ultrasound pulse.
Barcode sign
The barcode sign, also known as the "stratosphere sign," is a key finding in lung ultrasound, appearing in M-mode when
Beam divergence
In physics, particularly relevant to medical ultrasound, beam divergence describes the spreading out of an ultrasound beam as it travels
Beam hardening
Beam hardening in medical ultrasound refers to an artifact where the sound beam's average frequency increases as it travels deeper
Beam steering
Beam steering in general imaging ultrasound precisely directs the ultrasonic beam, optimizing image quality and diagnostic accuracy. This advanced technique
Beam width artifact
A beam width artifact in medical ultrasound occurs when the finite width of the ultrasound beam averages echoes from structures
Biceps tendon subluxation
Biceps tendon subluxation, in musculoskeletal (MSK) ultrasound, refers to the abnormal displacement of the long head of the biceps tendon
Biliary dilation
Biliary dilation, a key finding in abdominal ultrasound, refers to the abnormal widening of the bile ducts. This condition often
Billing
In the realm of Education/Administration within medical and ultrasound fields, "billing" refers to the comprehensive process of generating, submitting, and
Biophysical profile
The Biophysical Profile (BPP) is a non-invasive prenatal ultrasound assessment used in obstetrics and gynecology (OBGYN) to evaluate fetal well-being.
Biopsy guidance
Biopsy guidance in procedural ultrasound involves using real-time imaging to precisely direct a biopsy needle to a target lesion. This
