This page contains links to two types of data set packages:
1) the OpenArm Multisensor data set, which contains 2D time series ultrasound data (with muscle contour tracking code) alongside surface electromyography (sEMG), acoustic myography (AMG), and force data, and
2) the OpenArm 1.0 and 2.0 data sets, each of which contain full 3D data of the human arm under multiple conditions, alongside ground-truth and CNN-generated annotations of select tissue structures for select scans. All code and neural network models used in tissue annotation are also provided under a separate package.
See each package for details.
OpenArm Multisensor 2.0
This folder contains the second iteration of the OpenArm Multisensor data set and associated muscle contour tracking code. Included are 1) a multi-subject data set of ultrasound-based time series deformation data of the brachioradialis muscle alongside surface electromyography (sEMG), force, and goal trajectory data, and 2) all code used in analyzing deformation across subjects and optical flow tracking of muscle deformation over time.

OpenArm 2.0
This package contains the second iteration of the OpenArm data set, a multi-subject set of full volumetric scans of the human arm collected using ultrasound and motion capture. Data are factorial under multiple elbow angles and loading conditions, and thus allow for separable analysis of force- and configuration-associated muscle deformation. Improvements from OpenArm 1.0 include improved data collection procedures allowing for more explicit comparison of force conditions across angles, more subjects, and partial annotations for all subjects enabled by neural-network-based segmentation.

Data/images/video
This release contains full volumetric data of the arm for ten subjects under 20 force and elbow angle conditions, as well as 12 scans from one additional subject. Ground-truth segmentation data of the biceps brachii and ventral surface of the humerus are included for one full set of subject scans, as well as several scans of other subjects. Partial neural-network-generated segmentation data are included for all subjects and scans. See readme.txt for further information and the associated publication for a full description of data collection methodology.

This release contains full volumetric data of the arm for three subjects (Sub1, Sub2, and Sub3) under 20 force and elbow angle conditions. A subset of nine Sub1 scans are annotated with the full visible volumes of the humerus and biceps brachii, as well as sections of the ulna, radius, deltoid, brachialis, and brachioradialis.
