cardiac imaging newsToshiba America Medical Systems, a major company providing medical diagnostic imaging solutions, is expanding its suite of low-dose computed tomography (CT) technologies with Target CTA and Adaptive Iterative Dose Reduction (AIDR), which will be displayed this week at the RSNA annual meeting in Chicago.

Toshiba offers cardiac patients higher quality with lower radiation dose. 

Target CTA is a cardiac protocol for the Aquilion ONE CT technology that can view a pediatric or adult patient's entire heart in one rotation. Target CTA enables more accurate targeting of the heart, minimizes padding of the scan range, and can reduce the radiation dose during gated cardiac studies. Adaptive Iterative Dose Reduction is software that iterates noise out of the image to increase image quality and lower radiation dose. The software primarily improves the image by removing noise until the optimal image is produced. AIDR will come standard on the Aquilion Premium edition and Aquilion ONE.

Joseph Cooper, director of Toshiba's CT business unit, said: "Target CTA and AIDR represent Toshiba's continued commitment to providing patients with safer CT exams without sacrificing the diagnostic confidence physicians require." This announcement comes shortly after KLAS, a research firm specializing in monitoring and reporting the performance of healthcare vendors, issued a report that examined 12 products from four CT vendors. The report, "CT 2010: Slice and Dose," highlighted that Toshiba's products keep its forefront position with the company maintaining its perennial top rankings for both 64-slice and 16-slice CT products, with scores of 91.4 and 91.1, respectively.

Toshiba said Target CTA and AIDR join the lineup of its dose-reduction technologies, including SUREExposure, SUREExposure Pediatric, QDS, and Boost3D. SUREExposure and SUREExposure Pediatric adjust the dose levels each patient receives according to their size, age, and/or weight. Thus enabling physicians to obtain high-quality images with the least possible amount of radiation. QDS and Boost3D technologies improve image noise characteristics without increasing dose to the patient. These algorithms can be used to improve image quality while decreasing radiation dose.

Applying QDS and Boost3D can achieve dose savings of up to 50% while preserving reconstruction speed, according to Toshiba. Medical facilities conducting more niche exams can use Toshiba's dose-reduction software packages, including Variable Helical Pitch (vHP) and SURECardio Prospective. These technologies come standard on the Aquilion ONE and can be added to the Aquilion 32, Aquilion 64, and Aquilion Premium CT systems. VHP provides flexibility for scanning combination studies while considerably lowering dose and enhancing workflow. By improving the use of injected contrast material, vHP reduces the cost for hospitals or imaging centers and is safer for the patient. Toshiba said vHP can achieve a reduction of up to 55% in radiation dose over the use of a single gated pitch setting.

SureCardio Prospective combines the reliability and flexibility of helical cardiac acquisitions with the significant dose savings of prospective ECG gating. This technique produces high-quality diagnostic studies for all heart rates and can reduce radiation dose by up to 80%, the company noted. Moreover, Active Collimation, a hardware feature standard on the Aquilion Premium and Aquilion ONE, is used to minimize the effects of helical over-ranging and reduce patient exposure by blocking out excess exposure at the beginning and end of a helical exam.
