3D Heart Replica

Uses include individual study, for diagnosis and planning care.

3D-Printed Heart Replicas Look, Pump Like the Real Thing, By MIT News, February 24, 2023

A doctor holds a custom-made robotic heart.

MIT engineers are hoping to help doctors tailor treatments to patients’ specific heart form and function, with a custom robotic heart. Physicists at the Massachusetts Institute of Technology (MIT) led a team that developed a procedure to enable the creation of three-dimensionally (3D) printed replicas of patients’ hearts.

After converting medical images of a patient's heart into a 3D computer model, the researchers used a polymer-based ink to 3D-print a flexible shell identical to the patient's heart.

The researchers developed sleeves that may be wrapped around a 3D-printed heart and aorta to replicate a patient's blood-pumping ability.  Said graduate student Luca Rosalia, "The advantage of our system is that we can recreate not just the form of a patient's heart, but also its function in both physiology and disease."

More Digital Humans Emerging

Recall Microsoft's patent of a particular person, just mentioned here.   Recall too the 'uncanny valley', and other disturbing side-effects.   And the magic can collapse quickly of the conversation is not convincing.   But I expect this kind of play being quite common in not too many years.    I have mentioned our own primitive attempts here to simulate conversational brand equity.    Learned much before the capabilities were ready.

'Are You Real?'   By Gregory Goth, Commissioned by CACM Staff, January 26, 2021

A Digital Employee developed by IPoft company Amelia.

The digital human is a chatbot partnered with a lifelike avatar to add a visually relatable element to interactions.

Tyler Beck, chief operating officer of Dothan, Ala.-based Five Star Credit Union, recently began evaluating artificial intelligence-based technologies for the $500-million institution serving portions of Alabama and Georgia. As his research progressed, he said he was contacted by a vendor's representative via LinkedIn.

"When I finally got to talk to the company, the lady wasn't on the call," Beck said, "and it hit me she wasn't real. She was artificial intelligence. And not only was the interaction I had with her powered through AI, her profile picture was created through AI. That did a lot to tell me it was on a whole different level than I realized it was at. The functionality and use cases for AI, especially in financial services, is going to be great."

Among the latest iterations of AI-based platforms is the "digital human," a chatbot partnered with a lifelike avatar intended to add a visually relatable element to an interaction. Though Beck and many other business executives are not quite ready to pull the trigger on installing virtual tellers or advisors quite yet, several vendors are quickly emerging. The ecosystem that will enable their technologies to assume prominence is still in its infancy, but is growing quickly.

Additionally, vendors are branding their products to be readily identified as more than disembodied chatbots. New York-based Amelia (formerly known as IPSoft), for example, has trademarked the phrase Digital Employee for its platform, while Austin, Texas-based UneeQ's World Wide Web domain name is digitalhumans.com.

"We are fairly bullish on it," said Jim Lundy, founder and CEO of technology consultancy Aragon Research. "We've seen them in action. We are still in the very early innings and I say that because a lot of the bots that have been deployed thus far are terrible, but for every nine that are bad or average, there is usually one that is amazing."   ...

Patenting a Chat Bot of a Particular Person

The idea has been suggested before, here with slightly different capabilities.  Interesting depending hw well it could be implemented.   With image and realistic voice.   Consider too, who owns the particular replica of a person?    And how they are portrayed?     Worth patenting.

Microsoft patent would let us chat with the departed  by Peter Grad , in Tech Xplore

A chilling episode of the Twilight Zone that first aired 60 years ago focused on a young boy (played by Bill Mumy) who frustrated his parents by insisting he speaks to his grandmother daily on the toy phone she had given him just before she died. When his grieving and exasperated mother finally grabbed the phone to toss it away, she was startled to hear her mother's voice on the line.

The episode touched on the yearnings we all share of speaking one last time to a loved one no longer with us.

If a recently disclosed Microsoft patent comes to fruition, we'll be able to see, hear and converse with long-gone relatives. Or more accurately, with 3-D motion images complete with realistic voice reconstruction and distinct personality traits culled from a trove of the individual's communications on social media platforms. In short, a chat bot.

"Creating a Conversational Chat Bot of a Specific Person" is the dry but accurate title of a patent filed by Dustin Abramson and Joseph Johnson Jr. of Microsoft in 2017 and approved this month.  ... '
