To address such issues, scanner manufacturers have introduced iterative reconstruction algorithms to the market. In order to independently reduce noise and preserve resolution and image quality, IR methods use statistical and geometric models to variably weight the image data in a process that can be ...
4.2. Reference Diagnostic Imaging HN MRI investigations were performed with a 1.5-T (Avanto, Siemens, Medical Systems, Erlangen, Germany) or a 3-T (Signa, General Electric Medical System, Milwaukee, WI, USA) scanner. Morphological T1-weighted contrast-enhanced axial and coronal images with a 1...
To deal with this problem. Apple has come out with a new iPhone that uses biometric(生物识别的)information to lock itself up. The phone has a fingerprint scanner that will lock or unlock the phone. Your fingerprint becomes the key, and this makes it nearly impossible for others to use you...
CT exams were obtained by using 160-slice CT (CANON Aquilion SP Prime Scanner, Canon Medical Systems Corporation, Otawara, Japan). CT scans were obtained by setting the following technical parameters: tube voltage 120 kV; tube current modulation 300 mAs, spiral pitch factor 0.98; collimation 64...
