Using the ultrasound for therapeutic heat in PE

Hi all

Now I have been looking 3 hours after a 3 MHz machine in Europe, but unsuccessfully..

Is there any one who has found one?

Many from india!

Price under 500 $

Thinks!

Yes, i have the same problem. Looking for the right equipment for a reasonable price is really hard in europe. I’ve found something that looks exactly like copy of us pro 2000 and it costs around 160$. Still kinda expensive for me :(

I did everything like kyrpa did, I exchanged some messages with him in his thread(also read it all). The delta machine is SHIT, im telling it here so other users doesnt waste their money on that garbage. So shut up.

First warning. State your position and keep it objective, no need to tell members to “shut up”.

Use such disrespectful tone and/or language towards another member again and you will be put on hold.

Would a 1 Mhz ultrasound be effective? I saw this one - US 1000 3rd Edition Portable Ultrasound Therapy Device, want to know if this would be effective to use.

Thank you Sir, I was just trying to help since I did read all these threads related to US use.

It does work. Kyrpa made all his gains using a 1 Mhz machine, assisted with rice sock to keep the temperature up. Now If I was you, I would use the exact same model he has, the US 2000 Pro. I am not saying that the US 1000 will not work, is just that in order to replicate his results, I would use the same model he has.

I am personally still trying to find a good cost effective 3 Mhz, mostly because at 3 Mhz seems to make things more reliable as far as heating. The most reliable one as of now is the one Manko bought but is $800.

Hello all,

I have been away for a while and planning to be some more. I´ll be back.

Meanwhile search for the posts about effectivity on this thread. W/ cm^2 is the intensity which tells how much energy we put on the shaft while heating efforts.
US Pro 1000 has the maximum of 0.8 w /cm^2 , which it is not enough.
The consensus seems to be that we need 2.0 w / cm^2 or more to effectively produce enough heat.

Yes I have made it happen with a single 1.6 w/cm^2 in 20 minutes but it is not easy. I also needed to use external heat pad (rice sock) maintainining the heat while moving the transducer. The skin contact between shaft and the leg is highly beneficial with the 1 Mhz equipment.

I prefer multiple transducer setup. I found a low cost, effective enough application with using two 1.6w/cm^2 transducers simultaneusly as a dual setup. (US PRO 2000)

I do not understand then. When I lookt at US pro 1000 3rd generation description, they say this:

Output Intensity: 1.6W/cm² (Low), 2.6W/cm² (Medium), 4.6W/cm² (High)

How do you know that the max intensity is only 0.8w/cm²?

While the US pro 2000 have these description:

Output Power:
(L) 0.32W ± 20%
(M) 3.20W ± 20%
(H) 6.40W ± 20%

Effective Intensity:
(L) 0.08 W/cm2 ± 20%
(M) 0.80 W/cm2 ± 20%
(H) 1.60 W/cm2 ± 20%

I am Getting lost…

Kyrpa, I know your option of having 2 1Mhz transducers is way cheaper than a new machine, but isn’t 3Mhz more effective at heating tissues? Let us assume that we are heating up the top side of the penis where this “steel cord” runs which is the septum, it is is VERY close to the surface. Even more, if we use a fulcrum, with the tension added the penis flattens on top of the fulcrum exposing the septum literally 1-2millimeters under the surface. As far as I understand the 1Mhz frequency goes way deeper than the penis flattened on top of the fulcrum. Waves would be heating up the fulcrum in that case, while 3Mhz frequency targets 0.5cm in depth which would hit the septum more effectively than the 1Mhz.

Here is an interesting study where they discovered that 3mhz ultrasound goes deeper that they thought. 3mhz can effectively heat depth of 2.5cm and not just 0.8 - 1.6cm depth.

Hello,

Can´t blame you getting lost. Unfortunately it seems intentional on misleading buyers on these.
If you look closer you can findout that they tell the total output, so it is not actually the w / cm^2 intensity.

Output Intensity: 1.6W (Low), 2.6W(Medium), 4.6W(High)

The ERA (Effective Radiating Area ) being 6.6 cm^2 it gives the 0,696 w / cm^2.

Their data sheet actually gives 0,65 w / cm^2 for temporary max. output. I suppose it is calclutade by the total area of the head.

FutureShock just posted a great study.

Manko007 did make a comparison and the temperature reached 1MHz or 3MHz are similar. 3MHz just get you there sooner.
Both surely work, in theory 3Mhz is better on heating ratio but there are other positives on 1MHz one being better tolerated on higher intensities.

It depends a lot of on the shape and material of the fulcrum how it behaves. It wont be necessarily absorbed, it could be reflected back instead.
I am not recommending on using any reflectors whatsoever for safety reasons. Instead for the efficiency of 1MHz I do recommend using backing medium such as the flesh of your own leg firmly against the shaft. Or any other medium having similar acoustic impedance as the soft tissue, like the ultrasound gelpads do.

Let take it another shot. This time with greater accuracy.

ERA is 6.16 cm ^2

Therefor the maximum intensity is 0,746 w / cm^2.

And it operates in pulsed mode only (29% max). Fot the heating purposes continuous mode is needed(100%).

Anyways it is not enough.

I am not in the position to say which would be the best choice. There are many asking the similar question, I hope you don´t mind answering all at the same time.
In fact I am in favor of using multiple lower intensity transducers than sole higher performing one.

In general there are some specs to check out:

- Continuous mode crucial. Can be experessed as Duty cycle 100%.
- Intensity more than 1.6 w /cm^2. By the posts in here and from the literature we can say 2.0 w/ cm^2 being quite optimal.
- 1MHz or 3MHz, it is more about the way the heating is executed than the frequency.
- Look for the machines which has Non-uniformity Ratio (BNR) maximum of 5:1 . The smaller the ratio the better the waveform.
- ERA (effective Radiating Area ) minimum of 4cm^2 and maximum the diameter of this area still fitting flat against your shaft.

And keep reading the posts user are posting here on their experiences.
