Cut out the CDs and administration time that stands between you and a great consultation. Empower your patients to instantly upload or access imaging from within your patient portal.
Medical X-ray Imaging | FDA
Maximize time with patients while elevating their satisfaction and loyalty. Online scheduling and enabling patients to update their personal information in a portal is a great start. Our cloud image management solution quickly plugs into your portal and supports a broad range of file types.
It can even be customized to existing needs using flexible and comprehensive web-based APIs. Uploaded studies can then be accessed instantly from within the patient jacket of your EHR, or even from a mobile device. Are you spending time before or during an exam juggling with CDs to access studies or struggling with different proprietary viewers?

The film is then developed chemically and an image appears on the film. Film-screen radiography is being replaced by phosphor plate radiography but more recently by digital radiography DR and the EOS imaging. Plain radiography was the only imaging modality available during the first 50 years of radiology.
Due to its availability, speed, and lower costs compared to other modalities, radiography is often the first-line test of choice in radiologic diagnosis.

Also despite the large amount of data in CT scans, MR scans and other digital-based imaging, there are many disease entities in which the classic diagnosis is obtained by plain radiographs. Examples include various types of arthritis and pneumonia, bone tumors especially benign bone tumors , fractures, congenital skeletal anomalies, etc.
CT imaging uses X-rays in conjunction with computing algorithms to image the body. In CT, an X-ray tube opposite an X-ray detector or detectors in a ring-shaped apparatus rotate around a patient, producing a computer-generated cross-sectional image tomogram. CT is acquired in the axial plane, with coronal and sagittal images produced by computer reconstruction. Radiocontrast agents are often used with CT for enhanced delineation of anatomy.
Although radiographs provide higher spatial resolution, CT can detect more subtle variations in attenuation of X-rays higher contrast resolution. CT exposes the patient to significantly more ionizing radiation than a radiograph. On spiral multidetector CT uses or more detectors during continuous motion of the patient through the radiation beam to obtain fine detail images in a short exam time.

With rapid administration of intravenous contrast during the CT scan, these fine detail images can be reconstructed into three-dimensional 3D images of carotid, cerebral, coronary or other arteries. The introduction of computed tomography in the early s revolutionized diagnostic radiology by providing Clinicians with images of real three-dimensional anatomic structures.
CT scanning has become the test of choice in diagnosing some urgent and emergent conditions, such as cerebral hemorrhage, pulmonary embolism clots in the arteries of the lungs , aortic dissection tearing of the aortic wall , appendicitis, diverticulitis, and obstructing kidney stones. Continuing improvements in CT technology, including faster scanning times and improved resolution, have dramatically increased the accuracy and usefulness of CT scanning, which may partially account for increased use in medical diagnosis.
Medical ultrasonography uses ultrasound high-frequency sound waves to visualize soft tissue structures in the body in real time. No ionizing radiation is involved, but the quality of the images obtained using ultrasound is highly dependent on the skill of the person ultrasonographer performing the exam and the patient's body size.
Examinations of larger, overweight patients may have a decrease in image quality as their subcutaneous fat absorbs more of the sound waves. This results in fewer sound waves penetrating to organs and reflecting back to the transducer, resulting in loss of information and a poorer quality image. Ultrasound is also limited by its inability to image through air pockets lungs, bowel loops or bone. Its use in medical imaging has developed mostly within the last 30 years.
Because ultrasound imaging techniques do not employ ionizing radiation to generate images unlike radiography, and CT scans , they are generally considered safer and are therefore more common in obstetrical imaging. The progression of pregnancies can be thoroughly evaluated with less concern about damage from the techniques employed, allowing early detection and diagnosis of many fetal anomalies. Growth can be assessed over time, important in patients with chronic disease or pregnancy-induced disease, and in multiple pregnancies twins, triplets, etc.
Color-flow Doppler ultrasound measures the severity of peripheral vascular disease and is used by cardiologists for dynamic evaluation of the heart, heart valves and major vessels. Stenosis, for example, of the carotid arteries may be a warning sign for an impending stroke.
