MedTech West seminar with brain image researcher Emilia Gryska
När: 10/11/2020 , 12:00 - 13:00
Findings of a scoping review of automatic brain lesion segmentation methods on MR images of the human head, and the implications for the clinical practice.
In this digital lunchseminar, Emilia Gryska will talk about the findings of a scoping review of automatic brain lesion segmentation methods on MR images of the human head, and the implications for the clinical practice.
The results revealed plethora of algorithms and the predicted number of publications will grow at a staggering rate. The common validation and reporting practices in the field point to certain issues with reproducibility and generalizability of the results, which are necessary for a method suitable for clinical use. Brain image researcher Gryska will raise concerns if the current state and direction of the development of the field together with quasi-standard for algorithm validation are enough and relevant to evaluate clinical suitability of the developed algorithms. Her concern is a result of a large divide between the number of publications and no established clinical tools for automated brain lesion segmentation.
In this seminar, Gryska will discuss how to bridge the gap between research and practice, and what factors influence implementation of the algorithms as clinical tools. She will talk about results of a HealthcareInc project that she co-supervised. In the project, five master students got a task of finding out why there are still no automatic brain lesion segmentation tool in the clinic. The project takes a broad look at the problem, not only from the technical point of view. A big part of the issue lies in organizational aspects of implementing a new tool in a complex clinical environment. The project reveals factors that might play an important role in the implementation problem and give a basis for further studies investigating factors that hinder translating abundant scientifically validated algorithms into a clinical tool.
Emilia Gryska is a 3rd year PhD student at the Dept. of Radiation Physics at Göteborg University. Her supervisor is professor Rolf A. Heckemann at Göteborg University and MedTech West. Emilia has a master’s degree in biomedical engineering from Chalmers. A big part of her education involves image processing. Emilia´s interest in the project shifted from developing an automatic brain lesion segmentation methods to the very complex problem of implementation of the tools in clinical practice. The interdisciplinary field that she starts to venture into, poses big challenges, but also big rewards. Emilia believes that we have to focus on the interdisciplinary projects that take the user perspective as a priority to advance the hospital care and make use of available resources.
This is a digital seminar. Sign up at the latest on Monday 9 November at 12:00. Welcome!
