Clinical application for fixed radiography
VolumeRAD

When an X-ray is inconclusive, VolumeRAD™ provides additional information to assist radiologists with confident, diagnostic decision-making. The exam can be performed in <2 minutes at the same time and same system—with 20x less dose than a CT exam.1-5

At a glance

Frees up equipment

Leaves CT or MR systems open for more complex cases

Reduces patient anxiety

The <2-minute exam immediately follows X-ray so patients can get answers fast

Minimizes dose

A VolumeRAD exam has 20x less dose than a CT exam1-5

Highly accurate

Acquires multiple cross-section images of the anatomy in a single sweep

VolumeRAD improves clinical diagnosis by removing overlying structures, enhancing local tissue separation and providing in-depth information about the structure of interest.

Features
A fast and accurate alternative

Your department relies on standard radiography as the first diagnostic test for most chest, orthopedic and trauma cases. But hairline fractures or non-displaced fractures are difficult to detect on conventional X-rays.13 According to a recent study, 33% of scaphoid fractures are missed on the first X-ray.14



Digital tomosynthesis can help you reduce time-to-diagnosis, decrease department costs and improve patient outcomes.

How it works
Reduce costs and improve efficiency with VolumeRAD's fast, automated workflow
  • VolumeRAD takes multiple images of the anatomy in a single sweep including chest, abdomen, skull, sinuses, 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

  • Exam can be performed either at the wall stand or at the table

Lung nodule detection
Improve detectability of lung nodules and patient management15

VolumeRAD significantly increases detection sensitivity, enabling radiologists to confidently identify more lung nodules than 2-view chest X-ray. Radiologists also are significantly more accurate at correctly identifying cases requiring follow-up with VolumeRAD than with 2-view chest X-ray.15

  • VolumeRAD is 3.6 times more sensitive than chest X-ray in detecting lung nodules 3 mm to 20 mm in diameter, without decreased specificity15

  • VolumeRAD is 7.5 times more sensitive than chest X-ray in detecting lung nodules 4 mm to 6mm in diameter, without decreased specificity15

Metal artifact reduction
VolumeRAD Metal Artifact Reduction (MAR) provides quality multi-level image slices even with metal implants
Metallic implants often cause difficulty in digital tomographic imaging. Often black lines appear in the X-ray (an undershoot) or a white ring appears around the metal or there is streaking throughout the image. VolumeRAD Metal Artifact Reduction removes these effects, improving visibility, enabling analysis of implant placements and increasing clinical confidence.
