X-Ray Film Digitizer for Mammography CAD
The VIDAR Advantage
The CAD PRO Advantage® film digitizer has been specifically designed for mammography CAD. The American Cancer Society estimates the five-year relative survival rate from Stage I breast cancer at 98 percent versus just 16 percent for Stage IV breast cancer. Experts agree that routine mammography exams, when combined with mammography CAD, are the single most effective tool for detecting early signs of breast cancer. CAD systems incorporate advanced pattern recognition and image analysis capabilities designed to aid in the detection of subtle signs of breast cancer. These systems enable radiologists to improve their ability to detect early stage cancers in an efficient manner. A key component of these CAD systems is a high performance film digitizer that meets the highest standards of image quality and reliability.
Understanding Marketplace Needs
Unlike other manufacturers that take an evolutionary approach, VIDAR has created a revolutionary design for the CAD PRO Advantage in the important areas of image quality, film feeding and transport, and system speed. VIDAR worked closely with major CAD systems providers, mammography technologists, radiologists, engineering consultants, and quality experts to ensure that the CAD PRO Advantage meets the exacting needs of the mammography marketplace. The CAD PRO’s advanced technology will enable CAD systems providers to improve radiologists’ confidence in accurately detecting breast abnormalities. reliability and speed. In particular, film feeder reliability and speed are vital to productivity, as film feeder problems have the potential to disrupt operations, increase costs, and inconvenience patients. VIDAR, as part of its commitment to technology leadership, worked relentlessly to develop an innovative film feeder ® design. The continuous loading SmartFeeder is the anchor of the film digitizer’s reliability. The CAD PRO Advantage offers a modular 50-sheet film feeder. In addition, the advanced design of the feeder eliminates film jams, double feeds, and film pick-up problems that occur with other digitizers. Most importantly, the CAD PRO Advantage feeder is designed for continuous case loading. This feature allows the user to add cases without interrupting the digitizing process. In addition, the CAD PRO Advantage is able to digitize a four-film case in less than 120 seconds, which is 2X the speed of most other digitizers on the market, further increasing productivity. The CAD PRO’s modular design allows easy access for scheduled maintenance and field serviceable parts replacement to minimize downtime. VIDAR’s clinically proven technology and unique product designs continue to set the standard for excellence in a number of market segments, including PACS, teleradiology, telemedicine, mammography, and oncology. VIDAR’s digitizers are the choice of more than 100 systems solution providers.
Technology Advantage and Innovation
VIDAR has filed three patents related to the CAD PRO Advantage technology. Each of these patents applies to critical product attributes such as image quality, reliability, and system throughput. The CAD PRO Advantage offers unmatched spatial and contrast resolution, allowing radiologists to be confident that the image data the CAD system receives from the film digitizer is an exact representation of the original film. Additionally, VIDAR’s ADC™ (Automatic Digitizer Calibration) prompts the film digitizer to calibrate automatically before every film digitized; therefore, user intervention is not needed for this operation. In addition, the CAD PRO Advantage includes a closed-loop quality assurance system to help ensure the digitizer sub-system meets all MQSA requirements. This combination of technology results in virtually no variation in image quality from one digitized film to another, and ensures excellent grayscale reproduction in every image. This reproducibility, vital for mammography CAD, is another hallmark of VIDAR digitizers. Productivity and reliability will increase due to the digitizers’ exceptional reproducibility of image quality.
