Orthogonal signals - Study guides, Class notes & Summaries

Different tissues that have signals that appear similar on an MR image are described as: A) hypointense B) hyperintense C) isointense D) isodense - Answer isointense in a large main magnetic field such as those employed in MRI, the motion of a hydrogen proton has been described as wobbling like a spinning top. this motion is called A) precession B) resonance C) frequency D) angular momentum - Answer precession magnetic resonance imaging is derived from the process known as: A) ma...

Progression: Maintenance Tech I - II Conventional: Exam In the tree-and-branch architecture, how is the downstream signal from the trunk fed to the distribution branches? What is a common solution when congestion from modem activity and traffic becomes unacceptable in a hybrid fiber/coax (HFC) network? What technologies are defined in DOCSIS 4.0 to help sustain the hybrid fiber/coax (HFC) network infrastructure for several more years? How can a less-experienced technician identi...

NCTI ROC II BOOK II FINAL Test 1 question with correct answers rated A+ 2023 When pressure testing a drop system to check for leakage, What must be done before applying the test signal? - correct answer The technician must isolate the drop system from the hybrid fiber/coax (HFC) network by disconnecting the drop at the distribution tap. Why do some leakage detection systems utilize a leakage carrier modulated with a tagging signal? - correct answer To avoid false detection of leaks. When ...

ARDMS SPI STUDY GUIDE QUESTIONS AND ANSWERS ALREADY PASSED In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? 20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes for one complete wavelength to pass a fixed poin...
