Optimization of contrast enhanced digital breast tomosynthesis

To optimize this new method, this study searched for the beam quality that maximized image quality in terms of mass detection performance.

Technology Ultrasound Imaging July 12, Siemens Healthineers Launches Acuson Sequoia Ultrasound New system enables high-resolution imaging at greater depths without impacting real-time performance to improve imaging of different sized patients July 12, — Siemens Healthineers recently announced the launch of its new ultrasound system, the Acuson Sequoia.

The general imaging ultrasound system was developed in response to what the company calls one of the most prevalent challenges in ultrasound imaging today: With its new Deep Abdominal Transducer DAXa new high-powered architecture, and updates to elastography and contrast-enhanced ultrasound, the Acuson Sequoia produces penetration up to 40cm.

According to the World Health Organization, 1.

Because ultrasound imaging relies on the sending and receiving of echo signals to produce images, patients with more adipose tissue are more difficult to image. The deeper an echo signal needs to penetrate, the more attenuation occurs, resulting in image quality degradation.

Search form A reasonable compromise is a 0. A DE acquisition technique for a photon-counting DBT imaging system has been developed and optimized.

In attempting to overcome these challenges, clinicians have traditionally had to compromise on frame rates, resolution or penetration of their ultrasound imaging.

The new system provides high-resolution InFocus imaging throughout the entire field of view, from the near field to the far field, in real-time. Therefore, there is no need to adjust the focal point of the scan, resulting in faster scan time without compromising frame rates and resolution.

The new ultrasound system also offers high-resolution color flow, up to three times the sensitivity,1,3 and up to 20 percent deeper penetration. Imaging in these patients can be challenging, particularly in larger patients where the signals are attenuated.

The power architecture of the Acuson Sequoia provides six times the energy capacity available for shear wave elastography, enabling imaging at greater depths and a reduction in image variability.

In a collective effort to eliminate variability and long-term ergonomic injuries, Siemens Healthineers hosted workshops with worldwide ultrasound users to create a platform designed by the user, for the user.

The Acuson Sequoia improves workflow by introducing user-friendly features, such as gesture detecting transducers — activated by touch, automated protocols and streamlined registration that adapts to user preferences over time.

A new ergonomically designed InTune transducer family reduces operator stress while increasing comfort.July 12, — Siemens Healthineers recently announced the launch of its new ultrasound system, the Acuson Sequoia. The general imaging ultrasound system was developed in response to what the company calls one of the most prevalent challenges in ultrasound imaging today: the imaging of different sized patients with consistency and clarity.

New evidence on breast Magnetic Resonance Imaging (MRI) screening has become available since the American Cancer Society (ACS) last issued guidelines for the early detection of breast cancer in Digital breast tomosynthesis (DBT) is a tomographic technique in which individual slices through the breast are reconstructed from x-ray projection images acquired over a limited angular range.

In contrast-enhanced DBT (CE-DBT) functional information is observed by . contrast-enhanced tomosynthesis. The optimization was based on mass conspicuity for iodinated lesions. A ray-tracing algorithm was used to examine the signal difference to noise ratio (SdNR) of iodinated masses imaged with a wide variety of beam energies, filter materials and filter thicknesses.

Contrast-enhanced digital breast tomosynthesis (CE-DBT) is a novel modality for imaging breast lesion morphology and vascularity.

The purpose of this study is to assess the feasibility of dual-energy subtraction as a technique for CE-DBT (a temporal subtraction CE-DBT technique has been described previously).
