An exceptional tool for improved radiography workflow and efficiency, made for and with the TECHNOLOGIST in mind
• Designed for intuitive use
• Convenient workflow at point-of-care
• Facilitates hospital integration
NX is the technologist’s image identification and quality control tool.
NX has an intuitive interface that offers complete ease of use at the point-of-care.
Extensive range of benefits
NX offers a broad array of benefits developed with the technologist in mind. With the touch screen, the technologist can complete all standard tasks quickly and effortlessly. Thanks to the intuitive interface, easy access to the system is assured, providing more flexibility and efficiency in the radiology department.
Agfa HealthCare’s image processing allows the technologist to spend much less time adjusting, for faster image delivery to the radiologist. The in-room integration means a more convenient workflow for the technologist throughout the imaging process. Offering improved interoperability with other systems within the hospital, NX delivers a higher level of integration.
The NX workstation is a combination of identification, preview and finishing station. Thanks to an intuitive user interface is fast, flexible and efficient use guaranteed. NX optimizes workflow.
The NX platform provides very fast acquisition and a smooth workflow; its single, intuitive user interface for both DR and computed radiography (CR) requires minimal training but offers maximum convenience. Agfa HealthCare's gold-standard MUSICA2 image processing software has been specially tuned to further enhance the DR image quality, while the combination of needle (Cesium Iodide) scintillator and MUSICA2 provides the potential to yield high-quality diagnostic images at lower dose. DR solutions must meet high standards for productivity and workflow improvement, and very high image quality. We achieve this through the combined benefits of our NX workstation, Agfa advanced DR needle technology and our MUSICA2 image enhancement solutions.
For identification, the NX workstation consisting of a Windows XP workstation, equipped with an LCD touch screen display. The cassette in the CR30-X or the ID and the tablet placed examination research data are thereby coupled with the excellent picture.
In combination with a RIS, all relevant patient and examination data automatically fed via a DICOM Modality Worklist to the NX workstation. The data can of course, also be manually fed.
All images that one identifies on a NX workstation, appear by viewing the phosphor plate monitor of the appropriate drive. The NX drive can store the images (or forward) to an archive. One can choose to automatically archive images in a PACS, or manually forward these. The system can even provide an image or images to multiple destinations. For example a standard PACS archive destination, even in JPEG format.
NX makes image editing for the use of Agfa's patented imaging software MUSICA. Thanks to the MUSICA software, each image the maximum detail visibility guaranteed.
of course also be manually entered.
Almost immediately after placement of the casset in the image digitizer, a technical inspection is conducted by the lab technician. Also, corrections in the letter placement, mirror / rotation, window / level, etc. collimation adjustments can be made , and also corrections to the identification.
Designed for intuitive use
Increased flexibility thanks to minimal learning curve The screen windows have been purposely designed to answer the needs of the technologist: identifying patients, performing examinations, controlling image quality and transmitting the verified images. The touch screen makes the Worklist and Examination windows easy to use and quick to complete tasks.
With the intuitive GUI, only minimal training is needed to work effectively on NX: increasing the overall flexibility of the staff.
The most frequent tasks are the easiest to do
NX’s Worklist and Examination windows cover the technologist’s daily tasks. In the Worklist window, the technologist can enter patient data or select it from an RIS-based worklist (optional), while in the Examination window, he or she can identify a cassette, define the examinations to perform and take the necessary steps to prepare an image for diagnosis. The Examination window’s Fast Preview allows correct positioning and exposure to be determined even while the final image is in the process of being completed.
The hybrid touch screen/mouse provides greater efficiency
When precision work is needed, the mouse provides access to a broad array of special tools through the Editing window, such as zoom, manual collimation, window leveling, burn and edited image saved as New. The Editing window is optimized for hardcopy and softcopy viewing environments, with additional print tools available when images are displayed in the WYSIWYG print preview.
Image processing
MUSICATM provides excellent image quality NX includes Agfa HealthCare’s technologically-advanced image processing as part of the standard package. The Multiscale Image Contrast Amplification algorithm, MUSICA, composes the digital image in a number of different frequency ranges (or detail sizes) and modulates the signal amplitudes (or contrast) within each of these ranges. This single-dimension image processing delivers perceptibility and enhanced detail.
The optional, next-generation MUSICA2 takes image processing even further, with two-dimensional image processing, for both frequency and density (or grey levels). Both the technologist and the radiologist benefit from an improved workflow and higher productivity, while patients and healthcare facilities also gain from the substantial advantages (see ‘Optional features’).
Convenient workflow at point-of-care
More efficient workflow reduces examination time With NX, there is no longer a need for the technologist toleave the patient to perform any ID or image quality control activities. Plus, when NX is completely integrated with the X-ray system, there is no need to enter data into the X-ray console.

More comfort and less waiting increases patient satisfaction
The improved patient proximity allows greater efficiency and workflow for the technologist, with more comfort and a shorter waiting time for the patient.
An essential part of hospital integration
Connectivity between hospital systems and networks means better patient care NX plays a significant role in the hospital’s goal of providing patient comfort and care and improving communications throughout the facility via a total integration of systems. It supports the latest evolutions of hospital integration philosophy for improved interoperability.
NX is DICOM compliant and in accordance with IHE guidelines:
• DICOM images can be easily transmitted to a display station or imager for diagnosis. When sending to a PACS system, NX receives the message that images have been securely stored. Export of DICOM images to a CD-ROM for creating referral handouts is also included.
• An administrative tool is available to configure access rights for different users. With its password protection, NX provides security for patient information.
Optional Features for NX
NX covers the TECHNOLOGIST’s daily needs. When a facility has specialized requirements, multiple available options provide the specific tools the TECHNOLOGIST needs.
Imaging options
NX Precision Tools
NX Precision Tools allows the technologist to fine-tune the image and deliver more specific information to the radiologist.
• Annotations can be added to an image, such as: markers, predefined text, drawing lines or geometrical shapes, applying shutters to mask areas of the image, etc.
• NX Precision Tools measures distances and angles and determines leg length differences and scoliosis.
• Manual adjustment of the MUSICA image processing parameters allows fine-tuning for specific purposes.
NX Optiview
NX Optiview features minimize artifacts and optimize viewing quality for improved reading by the radiologist.
• The area outside the diagnostic area is automatically made black or grey, even when multiple exposures are made on one plate.
• Detected repetitive patterns, caused by anti-scatter grids, are removed.
• A square marker is automatically placed in the top left corner of all images. As the image is rotated and/or flipped, the marker also moves, indicating a manual change.
NX Quality Assurance
NX Quality Assurance helps the hospital maintain consistent image quality and minimize patient doses by monitoring dose variation on every exposure and analyzing rejected images.
• With the dose indicator, the technologist easily sees how much the exposure dose deviates from the reference value for the examination. The indicator compares the median absorbed dose (LgM) in each digitized image with a stored reference dose value for that type of exam, to monitor the dose consistency.
• NX Quality Assurance can also use the exposure index for digital X-ray imaging systems defined in the draft standard IEC 62494-1.
• A formatted summary report of the essential repeat statistics is provided as a basis for the department’s quality monitoring.
• A report with details on rejected images (e.g. rejection reason, technologist’s name and date) can be created for further analysis.NX Quality Assurance NX Quality Assurance helps the hospital maintain consistent image quality and minimize patient doses by monitoring dose variation on every exposure and analyzing rejected images.
MUSICA2 Next Generation Image Processing
MUSICA2 provides two-dimensional image processing for digital X-ray images, offering higher image quality, autonomy and robustness, while enhancing the productivity of radiologists and technologists.
• Two-dimensional (frequency and density) processing means bone and soft tissue are available in one image, but analyzed separately, eliminating the need to compromise on either contrast or density. The greater detail and improved image quality allow the radiologist to extract fast and secure diagnostic information, while decreasing time to view the image.
• The intelligent processing software automatically analyzes the characteristics of each image and optimizes the processing parameters, independent of user input (e.g. body part) and dose deviations, saving time and effort and increasing usability.
• The augmented robustness of the image quality reduces the need for window leveling and post processing for both radiologist and technologist.
MUSICA2 Platinum processing is available for hospitals with specialty areas that need increased emphasis on soft tissue or bone structure depending on body parts such as the chest, abdomen and musculoskeletal, and/or on patient groups such as paediatrics.
MUSICA2 Neonatal Processing is optimized for the generally difficult conditions of examining premature and full term newborn babies.
Even with the low doses appropriate for neonatal exams, or when using portable X-ray units, this processing provides optimal visualization of both lung and abdominal areas in a single image, while keeping the required focus on bone structures.
Conn ectivity options
NX RIS Connectivity
By decreasing typographical errors and allowing easy access to patient data, NX RIS Connectivity provides more consistent patient data and reduces identification time, resulting in improved technologist workflow.
