Description: |
The topic of this work was to realize a software-based approach for semiautomatic analysis of flow-mediated dilation (FMD) from ultrasound B-mode image sequences. The work is a continuation of a previous software project, in which B-mode ultrasound image and blood flow / ECG signal extraction, as well as the capability for manual analysis, was made possible. On this base, functionality for the semiautomatic assessment of FMD was built.
The result was a software that could be used for the aforementioned analysis. To validate this, functional testing was done. In addition, measurements of FMD were carried out using the software. These measurements were compared against those made by hand, as well as those received from another, commercially available software.

Tämän työn tavoitteena oli toteuttaa veren virtauksen säätelemän verisuonen laajenemisen (FMD) analysoimiseen tarkoitettu sovellustyökalu. Sovelluksen tuli ottaa syötteenä duplex-ultraääni-mittausdataa, ja antaa puoliautomaattisen analysoinnin jälkeen tuloksena FMD-prosentti. Työ tehtiin lisäkomponenttina aiemmin valmistetulle sovellukselle, joka mahdollisti edellämainitun manuaalisen analyysin.
Tuloksena saatiin sovellus, joka pystyi yllämainittuun analyysiin. Sovelluksen toiminnallisuus todennettiin erinäisin funktionaalisin testein, sekä tekemällä sillä mittauksia, joita verrattiin sekä käsintehtyihin, että kaupallisen sovelluksen tuottamiin mittauksiin.
