We therefore assume that EARL-compliant images would be useful for contouring of tumours with this algorithm in a multicentre setting.
EARL-compliant images could also be used in clinical routine in centres running more than one PET system, a situation that is more frequently being encountered.
So we put our money where our mouth was an invested in the largest in-image advertiser on the web, GumGum, whose network now reached over 100 million monthly uniques with 3 billion ad-compliant images, delivering an average CTR of 0.4% (2x industry average for banners).
This supports the use of EARL-compliant images in multicentre studies, where MATVs extracted from 18F-FDG PET are used for tumour targeting or as a prognostic tool (for example, using the median value of pooled data as a cut-off value).
This study examined MATVs delineated in stage IIIA-IIIB lung cancer patients, with the aim of comparing MATVs in PSF-reconstructed images optimised for diagnosis (PSF), PSF-reconstructed images with a filter chosen to meet harmonising standards (PSF7), and EARL-compliant images reconstructed using ordered subset expectation maximisation (OSEM).
Note that they may remove non-compliant photos, and they limit the number of times you can attempt to use non-compliant images.
The actual frame rate is 30 fps since NTSC-compliant image capture device is used.
Given an input model in one of the aforementioned formats, our simple web service can provide SBGN compliant SVG images in an HTML Inlineframe.
However, the use of EARL-compliant PSF images significantly improved these indices, demonstrating the value of harmonised-images, even when more advanced contouring algorithms such as gradient-based contouring are utilised.
The use of EARL-compliant PSF images (PSF7) resulted in volumes similar to those obtained with OSEM reconstructions (median = 34.6 cm3, interquartile range 7.9 to 51.4; no significant difference; Fig. 3a).
This study demonstrates that automatic contouring of lung tumours on EARL-compliant PSF images using the widely adopted automatic isocontour methodology is an accurate means of overcoming reconstruction variability in MATV delineation.
