Overview

VolumeRAD digital tomosynthesis

Today clinicians rely on standard radiography as the first diagnostic test for most chest, orthopedic and trauma cases. Advanced medical imaging is often ordered for complex cases that radiography cannot solve. These additional imaging modalities may result in higher radiation exposure, higher imaging costs, and a delay in diagnosis.&nbnbsp;

VolumeRAD Digital Tomosynthesis brings advanced volumetric imaging capability into your fixed radiography suite, helping you resolve suspicious x-rays “here and now” with a cost-effective technology and minimal added radiation.
With VolumeRAD:

  • Obtain multiple images of the anatomy in a single sweep at a low dose, including chest, abdomen, extremities and spine

  • Resolve inconclusive x-rays in orthopedic & trauma cases efficiently

  • Achieve superior lung nodule detection sensitivity compared to conventional chest x-ray 

10 years

Celebrating 10 years of VolumeRAD, GE Healthcare’s breakthrough in Digital Tomosynthesis. 

2015 marks the 10th birthday of VolumeRAD and we are proud to have served clinicians and patients across the globe by bringing 3-dimensional imaging into the digital radiography suite. 

The principles of tomosynthesis were known for many decades as a technique to produce section images of the anatomy. The development of new generation flat-panel detectors opened the door to practical clinical applications. GE Healthcare’s breakthrough came in 2005 with FDA’s 510(k) approval of “Revolution XR/d Digital Radiographic Imaging System with Tomosynthesis” – the first solution to bring volumetric imaging into a fixed digital radiography suite. R&D efforts continued and in 2013 GE announced the results of the Vortex study showing superior lung nodule detection sensitivity of VolumeRAD compared to conventional chest X-ray.  

10 years and 1200 installations later, we are proud to see that VolumeRAD is used in a variety of clinical situations across the globe including chest, abdomen, extremities and spine imaging. With over 50 peer-reviewed publications to date, VolumeRAD is also the subject of a growing number of scientific studies investigating its ability to provide three-dimensional information at lower dose and potentially lower cost than other advanced imaging modalities.

But our focus is on looking ahead. Our mission is to continue to touch the world with earlier answers and more hope to improve health and extend life.

How it works

VolumeRAD digital tomosynthesis

VolumeRAD provides multiple images of the anatomy in a single sweep at a low dose, including chest, abdomen, extremities and spine.

During the sweep, up to 60 ultra-low dose exposures are obtained. Similar to CT exams, the acquired data is then reconstructed into a set of tomographic images (parallel to the detector plane). These images, in DICOM format, can be reviewed sequentially on the acquisition console or on any standard PACS review workstation.

Acquisition sweeps can be performed either at the wall stand or at the table. There are four sweeps available


Wallstand Horizontal Sweep: Horizontal sweep of the tube for supine
imaging at the wall stand (requires extended arm and mobile table)



Wallstand Vertical Sweep: Vertical sweep of the tube for upright imaging




 

Table Horizontal Sweep: Horizontal sweep of the tube for
supine imaging



 

Wallstand Cross-table Sweep: Cross-table sweep of the
tube for cross-table imaging at the wall stand

             

Lung

VolumeRAD for lung nodule detection

The detection of lung nodules and subsequent patient management can be difficult with traditional chest radiography.
A recent international multicenter clinical trial has demonstrated that GE Healthcare’s VolumeRAD* Tomosynthesis imaging of the chest offers improved detection and management of patients with lung nodules compared to conventional radiography.

It delivers:

  • Superior lung nodule detection sensitivity compared to conventional CXR (7.5 increase in lung nodule sensitivity for nodules between 4 mm and 6 mm diameter vs. standard X-Ray)
  • Improved identification of cases that require follow-up [2] (1.5 times more sensitive than two-view CXR without decreased specificity) 
  • Improved conformity with guidelines for patient follow-up and care 
  • Improved sensitivity of detection of small lung nodules in the range of 3–20 mm in diameter; 3.6 times more sensitive than conventional two-view CXR, without decreased specificity
  • A minimal-dose, volumetric imaging technique with the simplicity and efficient workflow of conventional chest X-ray; superior to CXR for lung nodule detection [1] (patients receive only 1.6 times more radiation than they do with a two-view (PA and LAT) chest X-ray exam)

In this webinar learn how one of the top academic radiology departments in North America is using VolumeRAD
Digital Tomosynthesis to improve the detection of small lung nodules.
Dr. Kicska, Associate Professor of Cardiothoracic Imaging at University of Washington
discusses the advantages and limitations of Digital Tomosynthesis and how this cost-effective technology could
be used to resolve inconclusive x-rays "here and now", with minimal added radiation. Dr Kicska discusses:

  • Basic principles of digital tomosynthesis, its advantages and limitations compared to standard radiography and CT
  • Clinical cases where VolumeRAD is used to detect pathologic conditions of the chest
  • Emerging applications of digital tomosynthesis in thoracic imaging

Some interesting clinical cases



[1] No clinical evidence has been established supporting the following claims in patients with active lung or pleural disease that could obscure pulmonary nodules, including fibrosis, emphysema, compressed lung, scarring, severe lung disease, and in patients with objects in or around the lungs that could obscure pulmonary nodules. The effectiveness of the device may vary depending on nodule prevalence and type.

Orthopedic

VolumeRAD for orthopedic practices

Today orthopedic specialists rely on standard radiography for diagnosing skeletal trauma, monitoring bone union, and evaluating the success of surgical interventions. Advanced medical imaging is often ordered for complex cases that radiography cannot solve. These additional imaging modalities may result in higher radiation exposure, higher imaging costs, and a delay in diagnosis. 

VolumeRAD digital tomosynthesis can be used to detect and monitor complex fractures and implants whilst being competitive when compared to other imaging modalities on radiation dose, workflow and economics.
