Automatic Measurement of Pennation Angle from Ultrasound Images using Resnets
Ultrasonic Imaging, 2021In this study, an automatic pennation angle measuring approach based on deep learning is proposed. Firstly, the Local Radon Transform (LRT) is used to detect the superficial and deep aponeuroses on the ultrasound image. Secondly, a reference line are introduced between the deep and superficial aponeuroses to assist the detection of the orientation of ...

Measurement of Skeletal Muscle Pennation Angle
2021Pennation angle (PA) is an important indicator for skeletal muscle activity, and automatic calculation of PA has high practical value in fields such as sports medicine and rehabilitation engineering. This chapter mainly introduces the automatic calculation methods used in PA measurement, especially focusing on those related to Hough transform and Radon

Can we just forget about pennation angle?
Journal of Biomechanics, 2022Skeletal muscle design studies, based on anatomical structure, extend back several hundred years. Accurate anatomical drawings show that many muscle fibers are oriented at an angle relative to a muscle's axis of force generation. This pennation angle has been reported in the skeletal muscle biomechanics literature, primarily in the context of trying to

Automatic Extraction of Muscle Fascicle Pennation Angle from Raw Ultrasound Data
2022 IEEE Sensors Applications Symposium (SAS), 2022Compact, wearable, wireless ultrasound (US) sensing systems are promising devices for the observation of human muscle dynamics, offering low power, non-invasive continuous monitoring of contracting muscles. Plane wave imaging is an ideal imaging modality to meet the high frame rate requirements of fast contracting muscles.

Short Communication: Pennation Angle Variability in Human Muscle
Journal of Applied Biomechanics, 2014The pennated arrangement of muscle fibers has important implications for muscle function in vivo, but complex arrangement of muscle fascicles in whole muscle raises the question whether the arrangement of fascicles produce variations in pennation angle throughout muscle.

Pennation angles of the intrinsic muscles of the foot
Journal of Biomechanics, 2001As mathematical models of the musculoskeletal system become increasingly detailed and precise, they require more accurate information about the architectural parameters of the individual muscles. These muscles are typically represented as Hill-type models, which require data on fiber length, physiological cross-sectional area (PCSA) and pennation angle.

Automatic pennation angle measurement in musculoskeletal ultrasound image
2012 International Conference on Computerized Healthcare (ICCH), 2012Pennation angle is the most often adopted sonomyography (SMG) measurement to quantify muscle activities under different contractions because of its independence on the position and the field of view in B-mode imaging. In this paper, a new paradigm for automatic pennation angle estimation was described, which used some unique features of musculoskeletal

The Relationship between SEMG and Change in Pennation Angle of Brachialis
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007Surface Electromyography (SEMG) signals have been widely used for the functional assessment of muscles. On the other hand, sonography has been commonly used to detect the morphological information of human muscles in both static and dynamic conditions.
