Toshiba launches world’s first dynamic volume CT system

Toshiba America Medical Systems : 27 November, 2007  (New Product)
Toshiba America Medical Systems has launched the world’s first dynamic volume computed tomography system.
The AquilionONE is an advanced diagnostic imaging system that aims to revolutionise patient care because it helps reduce diagnosis time for life threatening diseases like stroke and heart disease from days and hours to mere minutes.

For the first time, physicians can see not only a three-dimensional depiction of an organ, but also the organ’s dynamic blood flow and function. Unlike any other CT system, the AquilionONE can scan one organ - including heart, brain and others - in one rotation because it covers up to 16 cm of anatomy using 320 ultra high-resolution 0.5mm detector elements. This reduces exam time, as well as radiation and contrast dose, and dramatically increases diagnostic confidence. With the AquilionONE, the organ or area is captured in a single rotation at one moment in time, eliminating the need to reconstruct slices from multiple points in time.

With its ability to perform comprehensive exams, including functional studies, the AquilionONE reduces the need for multiple, duplicative tests and invasive procedures. As a result of this breakthrough technology, healthcare costs can be reduced because unnecessary tests can be eliminated and diagnosis times are faster.

'The introduction of dynamic volume CT marks an important milestone in the history of Computed Tomography,' said Doug Ryan, senior director, CT Business Unit, Toshiba America Medical Systems. 'AquilionONE is the culmination of a decade of dedicated research and establishes a new frontier in CT imaging, offering advanced applications that can significantly enhance patient care while reducing the cost of healthcare worldwide.'

The AquilionONE has the potential to save lives and improve the quality of life for many people, especially patients with neurological symptoms, specifically related to stroke. When a patient comes to a hospital’s emergency room (ER) exhibiting stroke symptoms, it can take hours to diagnose and treat the patient when time is of the essence. Typically, stroke patients will be taken first to the hospital’s CT system, but with current CT technology results can be inconclusive and additional tests such as MR exams are necessary, extending diagnosis time to as much as four or more hours.

With the AquilionONE, time-to-diagnosis can be reduced to minutes because complete functional data is acquired accurately and quickly with less radiation and contrast. The shorter diagnosis time could help improve patient quality of life.

For patients exhibiting symptoms of heart conditions, diagnosis time can be reduced from days to minutes. Typically, patients who come to the ER with chest pain are given multiple tests to identify the problem, including an EKG, calcium study, CT angiography (CTA), nuclear test and catheterisation. Tests of this nature could take days to complete and would expose the patient to significant radiation and contrast dose. With the AquilionONE, a single comprehensive exam can give physicians all of the information they need to diagnose and treat the patient in less than 20 minutes and with significantly less contrast and radiation dose.

Toshiba’s road to dynamic volume CT began a decade ago. The development of the Quantum Detector technology platform made it possible to produce the industry’s thinnest detector elements at 0.5mm with the industry’s best low contrast resolution. In addition, this completely new system is equipped with innovative features including an exam table that accommodates up to 650lbs and coneXact dynamic volume CT reconstruction.

Prototypes and beta systems have been under rapid development. In 2006 and early 2007, AquilionONE beta systems were tested at Fujita Health University and the National Cancer Center in Japan and Johns Hopkins University in the USA. Feedback from the beta systems have been integrated into the system to ensure the best possible clinical outcomes.

The first commercial unit has been installed at Fujita Health University in Japan since October 20, 2007, followed by Johns Hopkins University in Baltimore, USA, Brigham and Women’s Hospital in Boston, USA, Humboldt University, Campus Charite Mitte in Germany and University Health Network in Canada.
