RADIOFREQUENCY (RF) - ELECTROMAGNETIC RADIATION LOWER IN ENERGY THAN INFRARED. THE RF USED IN MRI IS IN THE FORM OF A BURST OF RF ENERGY (PULSE) I THE 10 MHZ TO 100MHZ RANGE RF PULS, DELIVERED TO THE PATIENT BY RF TRANSMITTER. THE RF FREQUENCY, AT THE LARMOR FREQUENCY, RESULTS IN ROTATION OF THE NET MAGNETIZATION VECTRO AND PHASE COHERENCE OF THE NUCLEAR SPINS. AN RF COIL IS USED FOR TRANSMITTING AND RECEIVING MRI SIGNALS (RF). FRINGE FIELDS - WEAKER MAGNETIC FIELDS THAT ARE AWAY FROM THE I...

What are the 2 factors that affect image contrast in diagnostic imaging? - correct answer Intrinsic contrast parameters: are those that cannot be changed because they are inherent to the body's tissues. Ex) Bone density Extrinsic contrast parameters: are those that can be changed because they are under our control. Ex) TR What are examples of intrinsic factors? - correct answer T1 recovery time ...

ATOMS - Answer FUNDAMENTAL SUBMICROSCOPIC UNIT OF ALL MASS. SIZE OF THE ATOM AND ITS WEIGHT HAVE INTERESTED SCIENTISTS FOR A LONG PERIOD. SUBSEQUENTLY, EXPERIMENTS WERE DEVISED TO DETERMINE THE SIZE AND WEIGHT OF THE VARIOUS ATOMS. THE LIGHTEST OF ALL ATOMS IS HYDROGEN. PROTON - Answer A SUBATOMIC PARTICLE HAVING A POSITVIE CHARGE IDENTICAL IN MAGNITUDE TO THE NEGATIVE CHARGE OF AN ELECTRON AND, TOGETHER WITH THE NEUTRON, A COMPONENT OF ALL ATOMIC NUCLEI. THE PROTON FORMS, BY ITSLEF, THE NUCL...
