Which statement accurately describes Intense Super Pulsed (ISP) emission?

The statement that accurately describes Intense Super Pulsed (ISP) emission is that it includes thermal relaxation time between pulses. This characteristic is crucial because it allows the tissue to cool down between the pulse bursts, minimizing the risk of overheating and damage to surrounding structures. The thermal relaxation time enhances the effectiveness of treatment since it gives the tissues time to dissipate heat before the next pulse is delivered, making the therapy safer and more efficient for pain relief and promoting tissue healing.

In contrast, a 100% duty cycle implies a continuous output without pauses, which is not how ISP operates. Additionally, ISP does not operate at a constant low frequency; rather, it utilizes short, intense bursts of high energy. Finally, ISP typically delivers a higher energy output compared to continuous wave emissions, which allows for faster therapeutic effects rather than using less light energy.
