FDR AcSelerate integrates Dual Energy Subtraction and Tomosynthesis

Published on November 26, 2012 at 12:58 AM · No Comments

FDR AcSelerate, the fully automated positioning DR system from FUJIFILM Medical Systems U.S.A., Inc., will integrate two advanced applications to further extend diagnostic capabilities: Dual Energy Subtraction (DES) and Tomosynthesis (TS) . New Advanced Applications will bring significant enhancements to the Fujifilm DR portfolio that is being exhibited by the medical imaging and informatics company at the annual meeting of the Radiological Society of North America (RSNA).

"Healthcare professionals look to Fujifilm for innovations that improve patient experiences. These two additional Advanced Applications to our FDR AcSelerate DR suite will bring exciting new capabilities in diagnostic imaging," says Fujifilm's Rob Fabrizio, Director of Marketing and Product Development for Digital X-ray. "We continue to move forward with research and development that truly will make a difference in people's lives."

Dual Energy Subtraction (DES)
DES is an advanced radiographic technology in which two images are captured at different X-ray energy levels, then subjected to 'subtraction processing' to produce three resulting images: traditional, bone only, and soft tissue only. This process removes anatomical structures of high and low  x-ray absorption characteristics, such as soft tissue or bone, which along with other underlying and/or overlying structures can obscure suspected pathology. Fujifilm will be one of two diagnostic technology companies that currently has this technology.

Fujifilm's approach to dual energy subtraction will include three new advanced processing algorithms: (1) Multi-Stage Registration, or MSR, which intelligently corrects and compensates for patient motion, breathing or  heart beat artifacts that are typically characteristic of 2-shot Energy Subtraction; (2) Patient Size Compensation, which recognizes high density anatomy to optimize and clarify over- or under-penetrated areas of the entire image; and (3) Advanced Noise Reduction, which selectively helps suppress noise at multiple frequency levels without losing sharpness.

With Fujifilm FDR AcSelerate's DES, medical professionals will receive enhanced diagnostic detail from a routine follow up chest exam. It can be used as a great tool to help rule out the need for other, more dose-intensive exams.

Digital Tomosynthesis
FDR AcSelerate's Tomosynthesis will capture up to 60 rapid exposures in one fluid sweep, utilizing either the upright or the table. Images can be displayed in two modes: tilting mode and stack mode on its second monitor.  Images can then be displayed on a PACS workstation in a cine mode or frame by frame. Performing a TS exam can be particularly useful for exams such as head and neck trauma, shoulders, extremities, and chest exams to help visualize hard-to-find fractures or for prescreening patients to rule out the need for a traditional CT exam. That is especially beneficial to patients since it can be performed at considerably less dose than a CT exam.

For discussions on these advanced technologies, or for more information and demonstrations on Fujifilm's entire product portfolio, please visit booth #8316 at RSNA, which runs through November 30 at McCormick Place in Chicago.
