Toshiba launches new options for dual-detector radiographic system
Toshiba America Medical Systems unveiled upgrades to its Radrex-i dual detector radiographic system, including a mixed detector system and Auto-stitching capabilities, at the 2008 Radiological Society of North America (RSNA) in Chicago.
The new options available on the Radrex-i are poised to meet demands for improving patient care and increasing workflow by offering greater imaging versatility of patients on and off the table, as well as better coverage of long leg and spine studies, said Robert Micer, director, x-ray vascular business unit.

Toshiba showed a portable mixed detector option for the Radrex-i as a work-in-progress. The option features two high-resolution detectors, a 17-inch x 17-inch fixed wall-stand detector and a removable 14-inch x 17-inch portable table bucky detector. The Radrex-i mixed detector solution will provide the productivity of a dual detector system with the flexibility of a portable detector system.
Auto-stitching is an automated feature that will combine two or three 17-inch x 17-inch images into one continuous image for easy and accurate acquisition of long leg and spine images. This automated approach produces high quality images and increases productivity, while reducing the time and potential error associated with the manual reconstruction of such images.
Toshiba highlighted other Radrex-i features including:
  • Auto-tracking, which eliminates the need to manually position the x-ray tube detector by providing synchronization for table and wall-stand tracking;
  • Auto-collimation, which automatically selects the correct collimation size for the patient’s body part, saving crucial time for the patient and technologist;
  • Auto-program, which selects the correct program for each x-ray procedure, eliminating the need for the technologist to manually select the program on the generator; and
  • Auto-center stop, which provides visual guidance for detector centering.
The system also features a 600-pound table weight limit, 600 kHU x-ray tube and an 80-kilowatt generator and is configured with two high-resolution 17-inch x 17-inch detectors to ensure image quality with the lowest possible dose.
