Minimum Information Model for Dielectric Measurements of Biological Tissues

Welcome to Bio-MINDER!
This page describes the Minimum Information Model for Dielectric Measurements of Biological Tissues (MINDER).

The aim of MINDER is to provide a framework for recording and storing dielectric data and metadata for measurements conducted on biological tisues. The minimum information model facilitates the generation of data that is repeatable, interoperable, and re-usable. This page also hosts a database of the results and data obtained using the MINDER.

The data stored and maintained here conforms to the Minimum Information Model for Dielectric Measurements of Biological Tissues (MINDER) structure.

The dielectric properties are inherent characteristics of biological tissues. These quantities, namely, the relative permittivity and conductivity define the interaction of electromagnetic fields with the human body.

Dielectric properties are used in the design and development of electromagnetic medical devices, including diagnostics such as microwave imaging, and therapeutics such as ablation or hyperthermia.

​Dielectric properties are typically measured through a straight forward process. However, the properties may vary considerably based on factors such as temperature, tissue state, and probe position. For this reason, it is important to record relevant metadata during the measurement. With the metadata and data combined, dielectric properties of tissues can be interpreted properly and used in a reliable way.

​To facilitate this, the MINDER minimum information model has been defined. This structure includes all key types of metadata and enables sharing sharing of data across studies and applications.

The MINDER schema is illustrated below.
