Release of the Breast Tumor Patient Models Repository

IT’IS is pleased to host a new repository developed at the Erasmus University Medical Center that consists of 22 unique breast models for hyperthermia research. The Breast Tumor Patient Models hold important variations in terms of tumor size, tumor location, and tumor depth.

IT’IS develops highly detailed whole-body and partial-body virtual human and animal models as part of our Virtual Population (ViP) and ViZoo projects. Today, we are happy to announce the release of the Breast Tumor Patient Models (BTPM) Repository, a new open-source repository that was developed at the Erasmus MC Cancer Institute, University Medical Center in Rotterdam, and that will be hosted by IT’IS.

The BTPM Repository consists of 22 unique breast models each segmented into five tissues plus a tumor tissue from contrast enhanced MRI data of breast cancer patients undergoing neoadjuvant chemotherapy.

Developed in the context of intact breast hyperthermia studies, the repository covers a broad variation of breast anatomy and of pathological characteristics such as tumor position, size, and shape, thus facilitating an objective comparison of the heating quality for different hyperthermia devices using the same set of patient-derived models.

The paper by Ioannis Androulakis and colleagues published in September in the International Journal of Hyperthermia includes a detailed description of the creation of these models.

IT’IS is pleased to host and distribute this repository as it provides a unique platform for the optimization of hyperthermia treatment planning workflows and for the rapid development and evaluation of new hyperthermia devices.

All 22 breast models are distributed as STL files (open file format supported by all major simulation and CAD tools), as well as in voxel format.
