Next-Generation 16-Slice CT System Features Iterative Adaptive Dose Reduction Capability

A new 16-slice computed tomography (CT) scanner's adaptive iterative dose reduction (AIDR) feature could reduce patient radiation dose by as much as 75%.

Toshiba Medical Systems (Tokyo, Japan) has rolled out Aquilion RX, a new 16-slice CT scanner, which incorporates the latest dose-saving technologies based on iterative dose reduction.

the Aquilion RX was first presented at the European Congress of Radiology (ECR), which took place in Vienna, Austria, March 3-7, 2011. Aquilion RX completes Toshiba's 16-slice segment, and offers maximum performance for customers who need to perform a wide variety of routine clinical examinations in a streamlined workflow with the objective of delivering high diagnostic quality at a minimal level of radiation exposure.

"As part of Toshiba's commitment to deliver innovative technologies to a wide range of users, Aquilion RX has been developed as an economical CT scanner for general use, while embodying the flexibility usually seen only in the top-class segment,” said Mr. Yasuo Nobuta, vice president, and general manager of the CT systems division, Toshiba Medical Systems Corporation. "With AIDR, the adaptive iterative dose reduction technology implemented in Aquilion RX provides excellent image quality at the lowest dose.”

Using AIDR, image noise levels can be reduced by up to 50%. At comparable quality, the patient dose can be lowered by up to 75% compared to conventional scanners. Images iteratively processed with AIDR assure excellent image quality at the minimum dose for each patient.

A new computer platform for Aquilion RX provides a 60% faster reconstruction time. Moreover, SUREXtension, a thin-client display station, makes it possible to review images anywhere in the hospital without relying on a picture archiving and communication system (PACS) system, increasing patient throughput and shortening waiting times.

Aquilion RX incorporates Toshiba's exclusive, industry-leading quantum detector technology. The 0.5-mm element size and cutting edge reconstruction provide highly detailed imaging. Using the full width of the detector, fast scanning over a long range can be achieved in the case of emergencies or if there are breath-holding restrictions.

The advanced range of applications implemented in Aquilion RX supports all the clinical needs that a 16-slice scanner is expected to meet. A powerful 7.5-MHU tube ensures that scans can be performed without leading to unnecessary waiting times.

Prior to the official launch at ECR 2011, several orders were accepted, and the first installations will be performed immediately after ECR. "We received very positive reactions to the excellent specifications of Aquilion RX, and are convinced that this new system will further increase Toshiba's presence in this important 16-slice segment,” said Mr. Henk Zomer, Business Unit Manager CT, Toshiba Medical Systems Europe.
