A letter to Dr JD Thomas during ASE2021

Hopefully, you won’t get another letter during ASE2022.

Doppler spectrum precision measurement will reveal more secrets of hemodynamics

Background

For many years, the Doppler spectrum was measured manually in most of times. Their shortcomings include time-consuming, less accuracy and unacceptable variation between operators. A promising automatic measurement is dawning thanks to the Doppler spectrum enveloping widely used in vascular ultrasound, yet the technology needs dramatically improved. In the point of view of engineering, a more accurate measurement is doable with the neck breaking developing computer technology. This issue is overlooked mainly for sake of barely no clinical demand. And now, it is brought in front of us due to measurement of Tau. Tau, left ventricular diastolic time constant is an established best index to describe diastolic function. The non-invasive measurement of tau theory is perfect, [1,5] the practice lags behind because the Doppler measurement accuracy is not satisfactory. From other point of view, less accurate measurement can lead to weird conclusions, even for some celebrities. [6,7]

Cao in My Eyes and Beyond

Recently, several articles from top scientific journals are the culmination of years of cracking down academic fraud campaign. Unfortunately, Cao Xuetao became the key role. With the absolute dominant influence of the journals over research area, Cao is almost the most infamous scientist right now. The Chinese Ministry of Science and Technology was also blamed for failing to handle the whole process properly.  

Dr Luigi's concern

Tau2020

One year ago, we realized the dominant Harvard Tau method has to be removed after so many rejections it caused. The reasons of rejection are “priority is not high enough”, “the Harvard Tau method is better”, “this is between Dr JD Thomas and you”…So,

The 7th letter to Dr JD Thomas

Dear Dr Thomas,

This is the 7^th letter to you. Because all the previous ones were ignored, it might be a good idea to go public.

Please formally address your Tau formula which is logically flawed in our opinion.

Verification of flawed theory needs manipulated data, which is a hot topic in the whole medical publishing industry right now.

Inspired by the recent American election, let’s give each other a chance by exchanging ideas.

We might be wrong, please show us the right way.

Why We Measure Tau?
