Covering the basics of X-rays, CT, PET, nuclear medicine, ultrasound and MRI, this
textbook provides senior undergraduate and beginning graduate students with a broad
introduction to medical imaging. Over 130 end-of-chapter exercises are included, in
addition to solved example problems, which enable students to master the theory as well
as providing them with the tools needed to solve more difficult problems. The basic
theory, instrumentation and state-of-the-art techniques and applications are covered,
bringing students immediately up-to-date with recent developments, such as combined
computed tomography/positron emission tomography, multi-slice CT, four-dimensional
ultrasound and parallel imaging MR technology. Clinical examples provide practical
applications of physics and engineering knowledge to medicine. Finally, helpful refer-
ences to specialized texts, recent review articles and relevant scientific journals are
provided at the end of each chapter, making this an ideal textbook for a one-semester
course in medical imaging.

مقاله : Impact of miscentering on patient dose and image noise in x-ray CT imaging Phantom and clinical studies

The operation of the bowtie filter in x-ray CT is correct if the object being scanned
is properly centered in the scanner’s field-of-view. Otherwise, the dose delivered to the
patient and image noise will deviate from optimal setting. We investigate the effect of miscen-
tering on image noise and surface dose on three commercial CT scanners. Six cylindrical phan-
toms with different size and material were scanned on each scanner. The phantoms were
positioned at 0, 2, 4 and 6 cm below the isocenter of the scanner’s field-of-view. Regression
models of surface dose and noise were produced as a function of miscentering magnitude
and phantom’s size. 480 patients were assessed using the calculated regression models to esti-
mate the influence of patient miscentering on image noise and patient surface dose in seven
imaging centers. For the 64-slice CT scanner, the maximum increase of surface dose using the
CTDI-32 phantom was 13.5%, 33.3% and 51.1% for miscenterings of 2, 4 and 6 cm, respectively.
The analysis of patients’ scout scans showed miscentering of 2.2 cm in average below the iso-
center. An average increase of 23% and 7% was observed for patient dose and image noise,
respectively. The maximum variation in patient miscentering derived from the comparison
of imaging centers using the same scanner was 1.6 cm.
