CHAPTER D . 2 Positioning the Patient This chapter gives you information about positioning the patient. D . 3 We will start with important information about positioning. Then, you will learn how to position the patient correctly. D . 3 After that, the standard accessories for positioning and their use in various examinations is discussed.
Page 342: Important Safety Information
To avoid danger of injuring the patient during table or gantry D . 3 movements, only positioning accessories approved by Siemens should be used. In this way also artifacts can be avoided which impair the image quality.(→ Page D.4-1 Accessories for Patient Positioning) D .
Page 343 Operation Positioning the Patient Artifacts When positioning the patient, please ensure that the object of D . 3 interest is as near to the center of the measuring field as possi- ble. If it is not, image artifacts may appear on subsequent recon- structions, such as MPR, 3D etc.
Page 344 Positioning the Patient Operation Avoid delays You can avoid delays by: D . 3 D . 3 Preparing the patient for the examination. Placing the contrast medium within reach before the exam- ination. In this way, you avoid delays. D . 3 Correct respiration If the patient must hold his or her breath during CT acquisitions, D .
