50.DICOM is implemented in almost every radiology,cardiology imaging and radiotherapy device X-ray,CT,MRI, ultrasound, ete.and increasingly in devices in other medical domains such as ophthalmology and dentistry.

27.The stability of the patient table is not at risk when scanning very heavy patient,but the correct functioning of the table (lift,positioning,precision) cannot be guaranteed 100%.

9.Although there are great differences among diagnostic X-ray machines for different diagnostic objectives,the fundamental structure of X-ray machines is similar ,which consists of X-ray generating device,X-ray imaging device and X-ray auxiliary device.

11.In the X-ray imaging device,detector and data acquisition unit of X-ray imaging device transform X-ray ,passing through human body,into electrical signal.

33.Superconducting magnets have zero resistivity at very low temperatures.

29.After the scan is completed ,you can adjust the window center and width for optimal viewing of the image.

44.At the present time, the eriphasis of nuclear medicine studies is more on its function and
chemistry than anatomic structure.

17.DSA ,based on flat panel detector, not only has the advantage of good image resolution, but also decreases the radiation dose received by patients and physicians.

1. Ultrasound and magnetic resonance imaging was added to the list of skills used by radiographers because they are also medical imaging, but these disciplines do not use ionizing radiation or X-rays.

25.However, for a scanner that dose not have 24/7 cooling , gantry power must be turned off (using the On/Off switch on the control panel ) when cooling is not available.
