    CPAP STUDY – DATABASE

    The aim of CPAP study is to test the effect of applying positive airway pressure (PAP) during CT acquisition to improve segmentation, particularly at end-expiration.

    CPAP DataBase is a register built for this study and records data on CT acquisitions in inspiration and expiration with 4 PAP protocols. Were recorded prospectively and compared to baseline inspiratory acquisitions in 20 patients. The 4 protocols explored differences between devices (flow vs. turbine), exposures (within seconds vs. 15-min) and pressure levels (10 vs. 14 cmH2O).

    CT scans were acquired with a 320-detector row, 0.5 mm slice thickness, at intervals of 0.4 mm, 80 × 0.5 mm collimator, tube voltage of 100 kVp, and tube current adapted for sex and body mass index.

    Database Version 3, dated December 7, 2023, comprises a total of 96 pulmonary nodules. It includes all the nodules present in the previous versions (Version 1 and 2), thereby incorporating the data from the earlier database and including the diagnosis and scan’s acquisition parameters. It can be downloaded below.

  • BronchoX

    BronchoX

    Project Description

    Virtual Bronchoscopy (VB) is a non-invasive exploration tool for intervention planning and navigation of possible pulmonary lesions (PLs). A VB software involves the location of a PL and the calculation of a route, starting from the trachea, to reach it. The selection of a VB software might be a complex process, and there is no consensus in the community of medical software developers in which is the best-suited system to use or framework to choose.
    We present BronchoX (Bronchoscopy EXploration), a VB software to plan biopsy interventions that generate physician-readable instructions to reach the pulmonary lesions. Our solution is open-source, multiplatform and extensible for future functionalities, designed by our multidisciplinary research and development group.
    BronchoX contains two main modules, the Planner module and the Intervention Module. The planner allows clinicians to browse the CT data, obtain a 3D reconstruction of the airway tree and plan the best path to reach the lesion. The planner provides different visualization tools that simulates a virtual navegation trough the respiratory tract. Finally, the Intervention module use the planner data to provide simple and clear instructions during operation time.

    Project Description

    iVENDIS: Intelligent In-vivo Endoscopy Navigation, Diagnosis and Intervention Support systems.

    One of the main limitations of endoscopic procedures is the impossibility to get accurate 3D measures and location of the injured tissue which may lead to the repetition of some interventions with an additional cost for the healthcare system. Another limitation is the lack of objective tissue characterization to allow in-vivo diagnosis, delaying decision taking and patient treatment beginning. Therefore, clinicians are in urgent need of systems able to provide on-line 3D measurements, 3D positioning and objective tissue characterization tools during the endoscopic intervention. iVENDIS aims at on-line extraction of physiological data from endoscopy interventional videos for building up better lesion detection, diagnosis and treatment planning systems.

    iVENDIS is composed by three main products: SENSA, 3DEND and SAIPHIC.

    Machine Vision group is also involved in this project.

    SENSA

    A system for Endoscopic Stenosis Assessment (SENSA) for real- time segmentation of tracheal main anatomical structures in videobronchoscopy to provide accurate standardized measurement of tracheal obstructions.

    3DEND

    3D Bronchoscopy Navigation and Diagnosis system (3DEND) for increasing the yield of lung biopsy that incorporates a virtual bronchoscopy planner taking into account the bronchoscope’s kinematic constraints as well as bronchi breathing dynamics in order to guide the bronchoscope operator in real-time to peripheral pulmonary lesions that currently cannot be reached.

    SAIPHIC

    A system for automatic in-vivo polyp histology characterization (SAIPHIC) for providing the first on-line objective lesion diagnosis system considering both tissue visual features and an estimation of polyp size.
