OVERVIEW
Intelect® Transport Combo
Beam Non-Uniformity Ratio (BNR) – By nature, an ultrasound beam is not homogeneous. The BNR is a ratio of the highest intensity
found in the beam field to the average intensity as indicated on the output display of the unit. This measure may not exceed 5.0:1. Because
of the areas of increased intensity, the sound head is moved continuously during the treatment.
Beat Fixed - Associated with the Interferential waveform, Beat Fixed is the parameter at which the beat frequency remains constant. When
the Sweep setting is turned off, you must select a fixed beat for the therapy session. The available settings for Beat Fixed are 1 to 200 Hz.
Beat Frequency - Associated with the Interferential waveform, Beat Frequency is the frequency at which the amplitude of the current
increases and decreases. The beat frequency is considered to be the therapeutic frequency and is measured in hertz (Hz).
Beat High - During a sweep, the Beat High setting is the highest number to which the beat frequency increases. The available range for
the Beat High parameter is 2 to 200 Hz. This parameter is unique to the Premodulated and Interferential waveforms.
Beat Low - During a sweep, the Beat Low setting is the lowest number to which the beat frequency decreases. The available range for the
Beat Low parameter is 1 to 199 Hz. This parameter is unique to the Premodulated and Interferential waveforms.
Burst - A burst is a series of pulses at a predetermined pulse frequency.
Burst Frequency (Freq.) - This is the number of bursts per second (bps). The available burst frequencies on the Intelect Transport Combo
are 1 to 10 bps.
Carrier Frequency (Freq.) - Associated with the Interferential, Premodulated and Russian waveforms, Carrier Frequency is the frequency
of the un-modulated medium frequency current. The carrier frequency for Premodulated and Russian is at a fixed frequency of 2500 Hz.
The available carrier frequencies for Interferential are 2000, 2500, 4000 and 5000 Hz.
CC/CV - This is the abbreviation for Constant Current/Constant Voltage. Constant current is a stimulator capable of delivering an electric
current that flows at the same amplitude regardless of changes in tissue impedance over time. Constant voltage is a stimulator capable of
delivering a source of voltage at the same amplitude regardless of changes in tissue impedance over time. Keep in mind that the amount
of stimulation is directly proportional to the current.
Channel Mode - The available channel modes are Single Channel (in which electrotherapy is distributed from one channel), Reciprocal
(where electrotherapy alternates between channels), and Co-Contract (where electrotherapy is distributed from both channels at the same
time).
