Accumetra Publishes Method That Predicts The Bias and Precision Performance of CT Lung Nodule Volume Measurements

08 / 03 / 23

Lung imaging researchers from Accumetra, Mount Sinai, and Cleveland Clinic published a manuscript in July indicating for the first time that CT lung volume measurements can be reliably predicted using a new calibration-based analysis method. The

study showed that good volume measurement prediction results (bias, precision) could be obtained even when using low-cost reference objects, specifically three rolls of 3M Scotch Tape (TM). This novel approach, which formed the underlying computer-vision, math, and physics foundation of Accumetra's CTLX1 and CTLX2 phantoms, is being used internationally to improve lung nodule measurements. Numerous research projects have been launched as a result of this work, investigating improved methods to predict how a CT scanner will perform when requested to measure the volume of small objects near the limits of CT resolution.

Accumetra Presents a New Lung Nodule Measurement Approach at the 2023 I-ELCAP Meeting in Verona

07 / 17 / 23

Accumetra’s founder and CEO Ricardo Avila delivered a presentation on June 29th at the I-ELCAP meeting in Verona, Italy. This presentation announced our newest findings on how to use a combination of AI, computer vision, and

imaging physics/signal processing to improve quantitative CT measurement performance of small objects by more than 600% (see image). We call this new technical approach Artificial Intelligence Targeting and Measurement (AITAM). AITAM has the potential to greatly improve our ability to detect early lung cancer and help identify new CT imaging biomarkers.

Study Shows 80% Long-Term Survival Results of Low Dose CT Lung Cancer Screening

11 / 22 / 22

A 20-year study conducted by the global I-ELCAP team confirms that low dose CT lung cancer screening has an outstanding 80% long-term survival rate. In those 20 years, I-ELCAP has supported around 90,000 lung screening participants,

almost 300 publications and numerous international study confirmations. The I-ELCAP lung screening protocol represents a major advance in the war on cancer. To read more, visit https://www.auntminnie.com/index.aspx?sec=sup&sub=cto&pag=dis&ItemID=138686

Accumetra and RSNA/QIBA Launch QIBA Conformance Certification Services at RSNA 2018

11 / 19 / 18

RSNA's Quantitative Imaging Biomarkers Alliance (QIBA) and Accumetra have launched the first QIBA Conformance Certification Service for verification of CT small lung nodule volume measurements. This new paid service enables clinical sites to verify that their

CT scanners and software analysis tools are performing at a sufficient level to reliably measure the volume and change in volume of small solid lung nodules. A clinical site receives an institution-specific QIBA Conformance Certification Mark that can be used to communicate the site's small lung nodule performance achievement. CT scanner and nodule analysis software vendors can also achieve QIBA Conformance Certification for their FDA-approved products and achieve a product-specific QIBA Conformance Certification Mark to highlight the performance of their products.

This launch comes after over a year of globally deploying and testing the new CTLX1 CT image quality phantom and a cloud-based and fully automated CT phantom analysis service. The map below shows the location of the 65 CTLX1 phantoms (yellow) that have been shipped and are being used to monitor and optimize CT image quality at clinical sites around the world, thanks to support from the Prevent Cancer Foundation. Cloud-based phantom analysis servers (purple) can analyze an uploaded CTLX1 scan and send back an automated CT image quality report containing fundamental CT image quality properties within 10 minutes.

To learn more about these new services, visit us at the Accumetra/QIBA exhibit booth (South Hall Booth #1024) at the 2018 RSNA Annual meeting or visit the QIBA Conformance Certification web page.

Accumetra to Present a Hot Topic Scientific Presentation at the 4th Annual World Congress of Thoracic Imaging

03 / 09 / 17

Accumetra will give a Hot Topic scientific presentation on the “Clinical Implications of CT Image Quality Variation in Low Dose Lung Cancer Screening Scans” on Tuesday June 20, 2017 at the 4th Annual World Congress of Thoracic Imaging. The presentation

will provide information on the level of fundamental image quality variation present at 27 international lung cancer screening sites and the potential impact of this variation on CT lung nodule measurement performance. The clinical sites participated in a first-of-its-kind crowd-sourced image quality study based on CT scanning and analysis of three rolls of 3M Scotch tape. More information on the presentation and the conference will be available at the World Congress of Thoracic Imaging website.

Accumetra To Present at the IASLC’s 17th World Conference on Lung Cancer in Vienna, Austria

12 / 04 / 16

Accumetra will present a poster (Abstract #6317) on Monday December 5, 2016 at the IASLC’s World Conference on Lung Cancer 2016 that will review the results of the CT Lung Screening Protocol Challenge. The CT Lung Screening Protocol Challenge, conducted

in May and June of 2016, was the first crowd-sourced and ultra-low cost study to help the lung cancer and COPD imaging research communities determine the best CT scanners and protocols for the detection and measurement of lung cancer and COPD. Within the two month data collection period the study obtained CT image quality data from 27 healthcare institutions, 54 CT scanners, and 130 individual CT scans. This first of its kind study data is now helping shape imaging protocol recommendations for lung cancer screening and COPD. The challenge results and potential implications for globally improving the quality of future population screening initiatives will be presented.

First Crowd-Sourced CT Image Quality Study Reports on Initial Findings

06 / 21 / 16

Accumetra presented on the initial findings and results of the first ultra-low cost and crowd-sourced CT image quality study at the Prevent Cancer Foundation’s Quantitative Imaging Workshop on June 13, 2016 in Bethesda, MD. Within a two month data collection

period the CT Lung Screening Challenge obtained CT image quality data from 26 healthcare institutions, 53 CT scanners, and 128 individual CT scans. The study found higher levels of CT image acquisition variability than expected. In addition, many opportunities to improve low dose CT screening scans for early detection and nodule change measurement were found ranging from better education and guidance on CT imaging protocols to features that future scanners could provide to support higher quality screening studies.

The Prevent Cancer Foundation’s press release on the challenge is available here.
