Moreover the app offers a telephony feature using VoIP enabling every aspect of mobile devices without compromising patient confidentiality. Last but not least, mRay works seamlessly with your existing infrastructure. A minimal server application needs to be installed which reads DICOM files from the disk and is able to receive files directly from your PACS. That’s all you need to start simplifying your everyday life at work! You can check out the app in a demo mode.

Image processing allows the calculation and visualization of healthy and abnormal tissues. The patient group, for which mRay can be used, includes all patients from whom radiological image data has been created for the purpose of diagnosis or treatment. In a worst-case scenario the medical condition of the patient may be critical. mRay can be operated in hospitals, medical practices, on the go or at home. The software is dedicated for mobile devices for fast and immediate access to radiologic images for informational purposes. When using mRay for diagnostic purposes, national regulations must be considered and an appropriate display must be used. mRay allows the display of images and data types that are defined by the Digital Imaging and Communications in Medicine (DICOM) standard (e.g. computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), fluoroscopy (XA), digital x-ray (CR), ultrasound (US)). The software offers common radiological software tools (e.g. windowing, measurements, thick slices and annotations).
