a new test tool for single photon emission computed tomography (spect)【敏感词】coincidence detection systems the phantom laboratory【敏感词】physicists, david goodenough, ph.d.【敏感词】steve dyer, m.h.s., have worked together to develop the specphan™ phantom. the new specphan™ design reliably performs routine quality assurance tests, as well as, extensive acceptance tests of single photon emission computed tomography (spect)【敏感词】coincidence detection systems. new features【敏感词】precise components extend testing capability【敏感词】save time. the specphan™'s time-saving cantilever case mount extends the phantom beyond the table edge, allowing small radius rotations previously restricted by the patient table. new test components include the externally-filled, low contrast chambers,【敏感词】slice thickness test ramps. the chambers enable three levels of hot and/or cold contrasts to be evaluated in three diameters. test ramps are used to measure slice thickness【敏感词】slice position. these measurements are critical for volume【敏感词】fusion imaging applications. these tests can be performed either manually【敏感词】automatically through automated software available from the institute for radiological image sciences (iris). |
