Specific CT 3D rendering of the treatment zone after Irreversible Electroporation (IRE) in a pig liver model: the "Chebyshev Center Concept" to define the maximum treatable tumor size.

Background: Size and shape of the treatment zone after Irreversible electroporation (IRE) can be difficult to depict due to the use of multiple applicators with complex spatial configuration. Exact geometrical definition of the treatment zone, however, is mandatory for acute treatment control since incomplete tumor coverage results in limited oncological outcome. In this study, the "Chebyshev Center Concept" was introduced for CT 3d rendering to assess size and position of the maximum treatable tumor at a specific safety margin.

Optimisation of the coagulation zone for thermal ablation procedures: a theoretical approach with considerations for practical use.

Purpose: This paper outlines a theoretical approach for optimisation of the coagulation zone for thermal ablation procedures and considerations for its practical application.

Methods: The theoretical approach is outlined in the Cartesian coordinate system. Considerations for practical application are implemented.

The Medical Imaging Interaction Toolkit: challenges and advances : 10 years of open-source development.

Purpose: The Medical Imaging Interaction Toolkit (MITK) has been available as open-source software for almost 10 years now. In this period the requirements of software systems in the medical image processing domain have become increasingly complex. The aim of this paper is to show how MITK evolved into a software system that is able to cover all steps of a clinical workflow including data retrieval, image analysis, diagnosis, treatment planning, intervention support, and treatment control.

Effect of tissue perfusion on microwave ablation: experimental in vivo study in porcine kidneys.

Purpose: To determine the effect of tissue perfusion on microwave ablation lesions in an experimental in vivo study in porcine kidneys.

Materials And Methods: Twelve kidneys of six pigs were studied. In each animal, two microwave ablations were created in one kidney without limitation of tissue perfusion (group 1).
