# Project Description
31+
32+
<!-- Add a short paragraph describing the project. -->
33+
34+
35+
**SlicerUltrasound** is a 3D Slicer extension that currently includes two modules: 1) **_Anonymize_**, which removes both metadata-embedded PHI and burned-in text from DICOM images, and 2) **_Annotate_**, which supports expert labeling of image findings.
36+
37+
The **_Anonymize_** module has been used at multiple hospitals (BWH, Lahey, Indiana Methodist to remove PHI from patient exams. Users import DICOM ultrasound images from their local folder, and apply probe-specific masking templates to remove burned-in identifiers. Users specify the transducer type—curvilinear or phased array—which determines the expected fan shape. By marking three or four points on the image, the module interpolates the imaging sector and masks any visual PHI outside this region while preserving diagnostically relevant content.
38+
39+
The **_Annotate_** module allows experts to annotate lung ultrasound video clips, focusing on features such as pleura lines and B-lines. It provides an intuitive interface for frame-by-frame annotation, supports multiple raters, and saves annotation data for future research and machine learning.
40+
41+
Our goals during the project week are to:
42+
1. Obtain feedback from developers and clinicians
43+
2. Implement changes to the extension
44+
3. Connect with and talk to others about the MONAI Ultrasound Working Group - Annotation and Anonymization subgroup.
45+
46+
