  • Achieving Safe DICOM Software in Medical Devices
    Master Thesis in Software Engineering & Management REPORT NO. 2009:003 ISSN: 1651-4769 Achieving Safe DICOM Software in Medical Devices Kevin Debruyn IT University of Göteborg Chalmers University of Technology and University of Gothenburg Göteborg, Sweden 2009 Student Kevin Debruyn (820717-2795) Contact Information Phone: +46 73 7418420 / Email: [email protected] Course Supervisor Karin Wagner Course Coordinator Kari Wahll Start and End Date 21 st of February 2008 to 30 th of March 2009 Size 30 Credits Subject Achieving Safe DICOM Software in Medical Devices Overview The present document constitutes the project report that introduces, develops and presents the results of the thesis carried out by a master student of the IT University in Göteborg, Software Engineering & Management during Spring 2008 through Spring 2009 at Micropos Medical AB . Summary This paper reports on an investigation on how to produce a reliable software component to extract critical information from DICOM files. The component shall manipulate safety-critical medical information, i.e. patient demographics and data specific to radiotherapy treatments including radiation target volumes and doses intensity. Handling such sensitive data can potentially lead to medical errors, and threaten the health of patients. Hence, guaranteeing reliability and safety is an essential part of the development process. Solutions for developing the component from scratch or reusing all or parts of existing systems and libraries will be evaluated and compared. The resulting component will be tested to verify that it satisfies its reliability requirements. Subsequently, the component is to be integrated within an innovating radiotherapy positioning system developed by a Swedish start-up, Micropos .

  • Image Formats
    Image Formats Ioannis Rekleitis Many different file formats • JPEG/JFIF • Exif • JPEG 2000 • BMP • GIF • WebP • PNG • HDR raster formats • TIFF • HEIF • PPM, PGM, PBM, • BAT and PNM • BPG CSCE 590: Introduction to Image Processing https://en.wikipedia.org/wiki/Image_file_formats 2 Many different file formats • JPEG/JFIF (Joint Photographic Experts Group) is a lossy compression method; JPEG- compressed images are usually stored in the JFIF (JPEG File Interchange Format) >ile format. The JPEG/JFIF >ilename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG/JFIF format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a signi>icant reduction of the >ile size. Applications can determine the degree of compression to apply, and the amount of compression affects the visual quality of the result. When not too great, the compression does not noticeably affect or detract from the image's quality, but JPEG iles suffer generational degradation when repeatedly edited and saved. (JPEG also provides lossless image storage, but the lossless version is not widely supported.) • JPEG 2000 is a compression standard enabling both lossless and lossy storage. The compression methods used are different from the ones in standard JFIF/JPEG; they improve quality and compression ratios, but also require more computational power to process. JPEG 2000 also adds features that are missing in JPEG. It is not nearly as common as JPEG, but it is used currently in professional movie editing and distribution (some digital cinemas, for example, use JPEG 2000 for individual movie frames).
