OpenWaves Arm Dataset
Overview
The OpenWaves Arm Dataset includes 7,526 arm phantoms designed to represent realistic wave-speed characteristics of human arms. These phantoms are immersed in a water medium to replicate real experimental conditions.
Dataset Structure
- X-ray CT-Derived Phantoms: 809 phantoms transformed from X-ray CT images.
- Diffusion-Generated Phantoms: 6717 phantoms generated using a stable diffusion model.
How to Access the Dataset
- Download Sample Data: Users can download a 500 kHz frequency-band sample dataset directly from Huggingface to validate data format and workflow compatibility.
- Download Speed Data: Download arm_train_speed.mat and arm_test_speed.mat from the OpenWaves Repository and Split them into individual files using split_data.m.
- Generate Full Dataset: Install the provided data generation software from OpenWavesInstaller.zip, to generate wavefield data for all frequencies (0.25 MHz to 0.60 MHz). The software supports customizable simulation parameters to replicate real experimental conditions. You can compare the first 8 entries in your generated test dataset with the provided sample dataset to verify the consistency.
