In order to improve patient healthcare, the institute wanted to develop its work in pathology. The aim was to offer real digital continuity in patient healthcare as well as participating in telepathology networks and meeting the requirements of experts in tele-expertise. Plus, Gustave Roussy is a leader in research. The Institute sought to develop analytical tools with the aim of facilitating quantitative and semi-quantitative assessments and to improve their reproducibility.

The solution :

TRIBVN Healthcare implemented an image network incorporating our CaloPix image management system. The software enables images to be indexed, searched for and viewed. These features are available from any medical workstation either on site or remotely by working within the network through the CaloPix Pocket web application.

CaloPix connects to the laboratory management system Diamic. This enables images to be acquired and viewed via the slide’s bar code and images are also automatically imported from the scanner to the patient’s record.

Gustave Rossy is equipped with the macroscopic solution Macro by TRIBVN. The Institute is also equipped with digital cameras as well as a scanner for the acquisition of microscopic images and digital slides.

Doctors now employ automated reproducible image analysis methods that enable tissue quantification in particular.

Furthermore, Tribvn Healthcare and Gustave Roussy are working together as part of a clinical validation project. A group of pathologists led a study aimed at comparing microscopic diagnostic methods. A high number of cases diagnosed using digital slides were then reviewed under the microscope.

Benefits :

  • Centralized management of all images
  • Information systems harmonization
  • Quantitative analysis automatization and reproducibility

The results showed that reading slides in CaloPix was as safe for patients as reading under the microscope.

« One of the primary objectives is to improve the management of patient records and enrich the results of examinations by exploiting the advances made available by digital technology for the acquisition, management and sharing of images. »

« A second objective is the deployment of image analysis tools as a means of facilitating certain quantitative or semi-quantitative evaluations which are now an integral part of the diagnostic process, and the improvement of their reproducibility. A third objective is the participation of the department in the telepathology networks which are currently in the course of development, and to meet the requirements of virtual expert networks: this is a necessity, in the light of the diversity of tumours treated within the department and the level of specialized expertise required for certain of these tumours. This also provides us with the opportunity to evaluate the expertise of our pathologists, specifically in the field of rare tumours. »

« Digital imaging offers unparalleled opportunities for education and training, whether through the constitution of image banks for consultation by trainee pathologists, the organization of non-campus-based training for the refreshment of knowledge and the development of anatomic and clinical consultations with our clinical, radiological and surgical colleagues. »

André Gavoille
IT Project Manager
« The integration of the TRIBVN Macro tool with our LMS (Diamic, Infologic) is a key point” according to André Gavoille, IT project manager. »

« This ensures a strong link between images and the patient record in the LMS (for technical and reporting purposes). For the deployment of the various components – workstations and servers – we have assessed the impact of the quality of both operators and documents upon the relevant prerequisites. This has allowed us to proceed with a well-managed deployment operation, providing our two teams with everything required for their collaboration.»

« This allows dedicated research teams to complete their work on the basis of virtual slides, thereby accelerating the production of their results. »

Dr. Jacques Bosq
Pathologists
« The consultation of images and the automated quantification of biomarkers will enhance the understanding of the pathology concerned, and will be conducive to the deployment of a therapeutic strategy which is best-adapted to each patient. »

Irène Villa
Digital Pathology Engineer
« Over and above this network, the department plans to develop a web platform. This platform will contribute to both training and care. The training element will incorporate a collected resource comprised of annotated macroscopic images and virtual slides, together with background information on the pathology concerned. Training and evaluation modules will also be included. For patient care purposes, this platform will permit the rapid and secure exchange of images, both in-house and externally, for intra-operative telediagnosis operations, the acquisition of second opinions, academic panel reviews and anatomic & clinical meetings, and as a resource for the conduct of subject-based seminars. »
