Siemens is adding CARE Analytics to its portfolio of CARE (Combined Applications to Reduce Exposure) applications. The new application allows dose received by patients during an examination with computed tomography (CT) systems, molecular imaging (positron emission tomography) PET•CT TruePoint™ systems, X-ray, fluoroscopy and mammography devices, and angiography systems to be analyzed and evaluated. Hence, CARE Analytics can help clinicians, for example, improve their scan protocols and work with reduced dose.
With a multiplicity of radiology devices from Siemens, the dose received by each individual patient is recorded in a standard file format which allows the future use and analysis of this data. These are the so-called DICOM™ dose structured reports – DICOM SR. The dose-relevant data in these files comprises, amongst others, information such as CT Dose Index (CTDIvol), dose length product (DLP), total recording time, and the dose surface product. Until now, this data has merely been archived in DICOM SR but was not further processed. CARE Analytics extracts the dose-related data from the reports and displays it in Microsoft® Excel® format, for example. Using data edited in this way, medical staff is able to compare the dose given during different examinations with one another in order to further improve the scan protocols. In addition, it is possible to ascertain the dose a patient has received on different systems over a series of examinations. Dose reporting between multiple hospitals is also possible. The increased transparency lets clinicians improve their working practices and spare more as in the past with the dosages given.
For radiological and nuclear medicine examinations that involve the use of ionizing radiation with X-ray fluoroscopy or radiodiagnostics, the medical profession generally applies the "ALARA" principle – As Low As Reasonably Achievable. The aim here is to strike an ideal balance between the required image quality and the radiation dose. In the most relevant imaging procedures, such as CT, X-ray, fluoroscopy, angiography, and molecular imaging, Siemens is one of the pioneers in the development of dose reduction technologies for many years. For its radiological devices that work with X-rays or radioactive tracers, Siemens has developed an entire range of technologies – Combined Applications to Reduce Exposure (CARE) – that enable the dose to be reduced significantly without compromising the image quality. CARE Analytics is the new member in a comprehensive portfolio of CARE applications which can help medical staff to reduce X-ray dose.
