"TMED-2 dataset" | Tufts Medical Echocardiogram Dataset (TMED)
Every image in this dataset is a 2D TTE image stored at 112x112 pixel resolution in PNG format. In TMED-2, we used metadata available in the raw DICOM files to ensure only the 2D TTE images from each study are included (filtering out doppler images, m-mode images, and colorflow images).
