Ohm's law equation - ANS V=IR EKG monitored patient should be __________, monitor chassis should be ___________ (nonconductive). Why - ANS ungrounded, grounded. Grounded patients would be able to conduct leakage currents. we don't want this lb to kg - ANS 2.2 lb = 1 kg F to C - ANS C=5/9(F-32) C to F - ANS F=9/5C+32 3 things that change automaticity of automatic cells - ANS 1. slope of phase 4 2. Change of threshold potential 3. Change of resting membrane pot...

Purpose of RF (B1) field - excite hydrogen protons RF energy is absorbed by tissues - within the volume of the RF transmit coil. This is a thermogenic process. Thermogenic process - Results in production of heat. Ex: RF energy absorption MRI local and whole-body tissue heating is due to - magnetic induction Types of RF coil designs --linearly polarized -circularly polarized (quadrature) Function of coils - -transmit only -receive only -transmit/receive Most common type of coil used - r...
