Rental, retrofit and trade-in are financial options for moving to digital radiographyimage of DR systems and cassettes

The benefits of moving from CR to DR are widely recognized by the medical imaging community. Radiology Today summarizes them as, “the technology is more efficient, quicker, and, most importantly, requires less dose to the patient.”

They also include  a more productive radiology workflow than computed radiography (CR). In fact, WellStar North Fulton Hospital told 24×7 magazine that DR reduces their processing time by 90 to 95%. With fast and efficient DR technology, they can see more patients and gain higher utilization of their assets.

The advantages of DR – along with upcoming reimbursement cuts for film and CR exams as a result of the U.S. Consolidated Appropriations Act (also known as HR 2029) – make a strong case for facilities to transition to digital x-ray. Yet at least 8,000 CR systems are still in use today, according to IMV Medical Information Division’s “2015 X-ray Market Report”.  Why the delay?

Some medical xray facilities are reluctant to make the transition because their CR systems are working reliably. For others, the biggest hurdle is finding a cost-effective path to upgrade their existing technology. Facilities also need to weigh whether they should make the move from CR to DR one room at a time or in one swoop.

Carestream Health recommends that radiology managers consider the age of each existing X-ray system, its current operating condition, and whether it provides all the necessary imaging capabilities. In some cases, the X-ray imaging system might need to be updated to deliver advanced features or enhanced productivity. In other cases, installing a DR detector can deliver a rapid conversion to DR technology that makes high-quality images available in seconds.

Carestream offers three smart options to help customers in the United States move from CR to DR without a large upfront capital investment: rental, retrofit and trade-in.

As a research scientist at Carestream Health, my recent work has focused on pediatric X-ray imaging – specifically, on the goal of achieving high-quality diagnostic images while minimizing dose. To explore potential solutions to this challenge, I initiated a study in collaboration with Samuel Richard, PhD, a fellow researcher at Carestream, and Sosamma T. Methratta, MD, of the Milton S. Hershey Medical Center in Hershey, PA. The study had two specific goals: 1) Determine the impact of a simulated reduced dose rendering on the detection of skeletal fractures in children, and 2) Evaluate the effect of enhanced skeletal processing on the same detection task. The methodology and results of this study were on display at RSNA 2015.

Imaging Products and Technologies That Can Help Reduce Dose

How is Carestream Supporting Efficient Utilization of Radiation Dose?

DRX-Revolution Mobile X-ray Unit

At Carestream we are doing our part to help minimize radiation dose by delivering high-performance image capture systems and specialized software that can help minimize dose while maintaining high image quality. Here are five of Carestream’s dose-related initiatives:

  • Deliver DR detectors with high detective quantum efficiency

Carestream’s DRX Plus 3543C, DRX-1C and DRX 2530C cesium iodide detectors deliver high detective quantum efficiency (DQE), which can produce a higher quality image (defined in terms of signal-to-noise ratio) than a device with lower DQE. Higher DQE can also deliver the same image quality at a lower exposure, which reduces patient dose. Cesium iodide detectors are particularly important for pediatric imaging applications since children’s sensitivity to dose is substantially higher than adults.

  • Offer systems that help optimize radiation dose efficiency

Carestream products offer sophisticated multi-frequency image processing algorithms as well as the flexibility to adjust image processing techniques through the modality’s

DRX-Revolutionが海洋博公園沖縄美ら海水族館に導入され、イルカなど海洋動物たちの撮影に貢献しています。 ここ海洋博公園は1975年に開催された沖縄国際海洋博覧会跡地に設置された国営公園で、沖縄の観光スポットのひとつとして人気のある沖縄美ら海水族館もこの公園の中にあります。約740種21000点ほどの沖縄近海に生息する生物を飼育しています。 動物管理チームサブリーダーの植田啓一氏は常駐する医師の一人で、動物の健康管理・体調管理を担当しています。インタビューで植田氏は、特に動物を水から出して固定及び拘束時間を考慮しなければならない点や種別に応じて撮影線量を変えなければならない点など、人と動物の撮影方法の違いを述べています。 動物の種別によっては非常に大型になるので、高線量で高画質な画像が確実に取得できること、カセッテを都度交換することなく何枚も撮影できることなどが求められます。 魚類チーム 主任技師の柳澤牧央氏は「Revolutionは、イルカの下に入れたカセッテを一回づつ入れ替えずにそのまま撮り続けることができるのが、今まで現像しないといけなかったものに比べると利点だと思います。」と述べています。 水族館は病院と違って廊下が整備されていなかったり、本体を押したり引いたりすることが困難な場合が多いのですが、DRX-Revolutionは軽い力で簡単に動かすことができ小回りが利くので非常に便利であると述べています。 インタビュービデオではDRX-Revolutionでの撮影の様子やスタッフのインタビュー内容をご覧いただけます。
