Abstract The Image-Guided Surgery Toolkit (IGSTK) is an open-source C++ software library that pro- vides the basic components needed to develop image-guided surgery applications. The focus of the toolkit is on robustness using a state machine architecture. IGSTK is implementedin C++. It is cross-platform,usinga build environmentknown as CMake to manage the compilation process in a platform-independent way. Because IGSTK is an open-source project, developers from around the world can use, debug, maintain, and extend the software. IGSTK uses a model of software development referred to as Extreme Programming. Extreme Programming collapses the usual software creation methodol- ogy into a simultaneous and iterative process of design-implement-test-release. The key features of Extreme Programming are communication and testing. Communication among the members of the IGSTK community is what helps manage the rapid evolution of the software. Testing is what keeps the software stable. In IGSTK, an extensive testing process (using a system known as CDash) is in place that measures the quality on a daily basis. The IGSTK Testing Dashboard is posted continuously, reflecting the quality of the software at any moment. This book is a guide to using IGSTK and developing image-guided surgery applications with IGSTK.

    ` VOLUME 3 ISSUE 6 Advantages and Disadvantages of using Third-party software in the development of the CAS_Annotate and CAS_Navigate Medical Applications 1João Fradinho Oliveira 1C3i/Instituto Politécnico de Portalegre, Portalegre, Portugal; [email protected] ABSTRACT This paper address the main design decision issues taken when using third party libraries in the creation of two medical applications [1] that specifically require editing or creating geometry from CT images (CAS_Annotate) and interactive 3D visualization (CAS_Navigate). Whilst the purpose of the first application was to research different 3D reconstruction algorithms, the second application was created to research different visual metaphors and the reconstructions themselves. This paper weights aspects such as the learning curve time versus coding in-house time, robustness and possible customization. In theory both applications could have been developed within the same IGTSK [2] framework, but the available project time and the development of different phases of the project made that impossible, instead a black box approach of using IGSTK's 3D Msh format was crucial to import algorithm results tested with a simple GLUT application, thus allowing development to be made in parallel. Keywords: Image guided surgery; 3D reconstruction; IGSTK. 9 Introduction Writing applications with third party software has always had many benefits such as access to functonality that would be prohibitive to implement in the time frame of a project, but also the known drawbacks regarding documentation and indeed the learning curve to be able to master and change those solutions at the required level for specific project needs. This paper outlines the requirements of two medical applications [1] CAS_Annotate (a tool that allows one to manually segment/edit contours of objects of interest in CT images and test-bed different 3D reconstruction algorithms) and CAS_Navigate (a tool that provides a road-map of pre-operative geometry of organs and vascular structures intraoperatively).

(CT) or magnetic resonance (MR) images ([5], [6], [7]). Unfortunately, the transition from an image analysis algorithm Such image fusion has already been developed for some to clinical feasibility trials as part of an intervention system requires integration of many components, such as imaging and clinical applications with the help of US tracking, and it has tracking devices, data processing algorithms, and visualization the potential to transform the way many other radiological software. The objective of our work is to provide a freely available interventions are performed. Also, US imaging has a limited open-source software platform - PLUS: Public software Library field of view.

A DICOM file format and communication protocol for pathology have been defined; however, adoption by vendors and in the field is pending. Here, we implemented the essential aspects of the standard and assessed its capabilities and limitations in a multisite, multivendor healthcare network. Methods: We selected relevant DICOM attributes, developed a program that extracts pixel data and pixel-related metadata, integrated patient and specimen-related metadata, populated and encoded DICOM attributes, and stored DICOM files.

Introduction Ultrasound (US) has a great potential in guiding medical interventions, as it is capable of acquiring real- time images, it has low cost, small size, and does not use ionizing radiation. Positioning of interventional tools can often be successfully completed by simple free-hand manipulation of the ultrasound transducer and surgical tools. However, there is a wide range of challenging procedures that require continuous tracking of the pose (position and orientation) of the images and surgical tools are required. Research and development of position tracked (also known as navigated) ultrasound guided intervention systems requires advanced engineering infrastructure, which has not been available in the public domain, and single project-based solutions have not proven to be suitable as reusable platforms.
