Central Denmark Region, Department of Procurement & Clinical Engineering wishes to purchase five licenses of deformable image registration (DIR) based software with DICOM standard medical images as a primary focus, for the Department of Medical Physics, Aarhus University Hospital.
Clinical field of application:
The Department of Medical Physics at Aarhus University Hospital requires software to complement Varian Eclipse 11 in aspects of processing functional imaging, auto-segmentation and deformable image registration for radiation therapy: We are in the process of implementing more adaptive radiotherapy treatment schemes. The processes involved require several imaging modalities and repeated imaging over the treatment course, as well as repeated contouring and planning. To minimise the workload of the often cumbersome workflows, as many steps of the process as possible should be automatable through scripting and server daemons.
The specific requirements of the software are described in details in the accompanying requirement specification, from which the vendors will be evaluated. The examples of workflows below are not intended to illustrate absolute requirements, but rather to depict the ideal capabilities of the software.
Examples of workflows:
1) The patient is scanned with CT, PET, MR and SPECT prior to treatment. The images are uploaded to a PACS server with a patient ID and a common tag indicating the type of patient (e.g. lung cancer patient) and one indicating the gender.
The software in question would ideally import all new images directly from the PACS database, recognize them as belonging to e.g. a female lung cancer patient, auto-segment predefined structures for a female thorax and register the different modalities of images.
2) The patient is set up using daily CBCTs. Ideally the software would import the CBCT images automatically from the image database as soon as the day’s treatment session is completed. The CBCT image would be registered to the planning CT image and doses deformed, or accumulated doses calculated, and an alert being issued if doses exceed a (template) predefined limit to any organ or if targets are underdosed. If this is not possible automatically, it should at least be possible to import and batch-deform 5 CBCTs to the planning CT, and perform the same dose/DVH analysis.
3) The patient needs a new plan during treatment. The images of a new CT scan are automatically imported to the software in question, DIR is performed with the original planning CT and structures are propagated to the new image volume and exported to the Varian Eclipse 11 database for re-planning.
4)Patient images including DWI-MR are required to be imported and automatically separated based on the different diffusion gradients (so-called b-values). These images will be used to guide tumor delineation and also evaluate tumor response to treatment. Ideally, if a map of the static magnetic field is present the DWI-MRI (EPI) images will automatically be corrected geometrically (Jezzard & Balaban 1995).
A complete requirement specification is enclosed.
The Department of Medical Physics reserves the right, to the necessary extent, to test the offered software in the required. Please state the possibilities for testing the software, and list possible reference sites with a similar clinical field of application, that may be contacted for the purpose of evaluating the tender.
