Managing a conflict of interest

Hello, 板倉重弘. We welcome your contributions, but if you have an external relationship with the people, places or things you have written about on the page Focused ultrasound, you may have a conflict of interest (COI). Editors with a conflict of interest may be unduly influenced by their connection to the topic. See the conflict of interest guideline and FAQ for article subjects for more information. We ask that you:

avoid editing or creating articles about yourself, your family, friends, colleagues, company, organization, clients, or competitors;
propose changes on the talk pages of affected articles (you can use the {{edit COI}} template)—don't forget to give details of reliable sources supporting your suggestions;
disclose your conflict of interest when discussing affected articles (see Wikipedia:Conflict of interest § How to disclose a COI);
avoid linking to your organization's website in other articles (see Wikipedia:Spam § External link spamming);
do your best to comply with Wikipedia's content policies.

In addition, you are required by the Wikimedia Foundation's terms of use to disclose your employer, client, and affiliation with respect to any contribution which forms all or part of work for which you receive, or expect to receive, compensation. See Wikipedia:Paid-contribution disclosure.

Also, editing for the purpose of advertising, publicizing, or promoting anyone or anything is not permitted. Thank you. Zefr (talk) 22:21, 13 November 2024 (UTC)[reply]

Hi, Zefr,I have a degree in thermal engineering and ultrasound. Unfortunately, I am also a patient with prostate disease, and I read the article on HIFU (High-Intensity Focused Ultrasound) on Wikipedia. However, I was disappointed when I looked at the heat equation. It seems to be something that applies to general solid structures like steel, where some kind of heat source is used, and it is nonsensical to include it here. It doesn't apply at all to elastic bodies. In fact, the heat equation used in this context does not account for the specific characteristics of ultrasound, such as wave propagation, energy absorption, or the interaction with biological tissue. Ultrasound energy transfer involves complex phenomena like cavitation and thermal deposition, which cannot be described by a standard heat equation meant for rigid bodies. Using this equation in the HIFU context misrepresents the physics involved and is misleading.

The equation for ultrasound in elastic bodies cannot be generalized, as it varies significantly depending on the conditions. Therefore, there is no simple equation that can be used to explain it to the general public, like on Wikipedia." 板倉重弘 (talk) 19:57, 19 December 2024 (UTC)[reply]

I also thought about the potential conflicts of interest, and it seems that many of the contributors you have listed are from India and China. If I’m not mistaken, the inventor who holds the patent for HIFU appears to be from India. I saw this information on the website of a company that makes prostate treatment machines. 板倉重弘 (talk) 20:14, 19 December 2024 (UTC)[reply]

The technical points made in your reply are likely worthwhile to have on the article talk page for consideration by others. When I reverted your apparent COI comment, you had said " We are in the process of updating FDA.gov content to reflect these changes" which suggests you are involved with a company ("we") while editing the article - that is COI. You could add the usernames of yourself and other colleagues to the talk page, where there are many others shown. It is probably best to not edit articles where you have a professional or personal conflict. Zefr (talk) 21:43, 19 December 2024 (UTC)[reply]

The logic of your reply is quite definitive for me. 1. I have only looked into HIFU as a patient. 2. I have not mentioned the FDA, but I know that it is not approved for prostate treatment because the URL of the device seller said that it was pending. 3. Also, as I said, it is completely out of place to mention the thermal method for elastic bodies here. You do not seem to understand the engineering concept. It was written those equations are completely unrelated. 板倉重弘 (talk) 13:37, 20 December 2024 (UTC)[reply]

Please don't just put "(We)" in there. I'm not Indian or Chinese. 板倉重弘 (talk) 13:57, 20 December 2024 (UTC)[reply]

I came up with an analogy. In a liquid-in-glass thermometer, the red alcohol rises and falls with temperature according to the room temperature, right? (This is described by the equation written here.) Now, what happens if you wrap the red bulb of the thermometer in fur? The temperature displayed will be completely inconsistent depending on the type of fur. The way it’s wrapped and other parameters will introduce so many variables that the equation becomes one with a complex set of integrals, containing additional nested integrals within the already intricate ones. The number of parameters becomes enormous. There’s no point in writing it out, or rather, it’s impossible to write. 板倉重弘 (talk) 14:34, 20 December 2024 (UTC)[reply]
