Conclusion

The Hologram is a system for non-expert healthcare, with the idea that it can be practised in any setting, although it would be more at home around the kitchen table than in a clinical setting. The Hologram describes itself as a feminist peer-to-peer health care system; that is to say, it is feminist in its approach and roles are fulfilled by the four participants; there are no professional or leadership roles. It is built from a very simple premise: three people, known as the triangle, meet on a regular basis, in person or online, to focus on three elements of the well-being of a fourth person, known as the hologram. These three elements are the physical, mental and social health of the hologram (the subject). In turn the hologram teaches the triangle how to give and also receive care. Over time, each triangle reflects a multifaceted image of the person, hence the term hologram. The viral nature of this system comes from the method of expansion, in which each member of the triangle seeks to become the hologram for a different triangle of people, and from there the same pattern repeats creating an ever expanding network.17 This work of art demonstrates that you don’t need professional expertise to create networks of care. You can gather a group of friends and care for one another.

Learning a motor skill is not by itself very useful if the learned skill cannot be stored and retrieved later. Where and how memories are stored and how they are retrieved remains conjectural. It is generally assumed that memories are stored in synapses. Macromolecules have also been implicated in memory storage and retrieval. In his classical experiments conducted early in the twentieth century, the American neuropsychologist Karl Lashley showed that rats retained the memory of a learned motor task even after 98% of the cortical areas related to the task were removed, irrespective of which areas were spared. This suggested a distributed nature of memory, as in a hologram, which is a two-dimensional recording on a photographic medium of an interference pattern produced by a laser beam, part of which is applied directly to the medium and the other part is reflected from a three-dimensional object. When a laser beam of the same frequency is applied to the medium, a hologram appears as a three-dimensional image of the object. Holograms of different objects can be stored on the same medium using laser beams of different frequencies. An important aspect of holography is that any small part of the hologram can be used to reproduce the image of the whole object, which means that the information on the object is stored in a distributed manner. What neuronal mechanisms can give rise to distributed memory also remains conjectural.
Holograms

In 2001, I was asked to create a hologram of a fractured spine “that would rise off the mediation table and spin around.” It was a hard assignment to convince the lead attorney otherwise, to tell him “impossible,” even after fruitless and embarrassing calls to Hollywood. Today, a “hologram” isn't out of the question. Especially if the judge will allow VR headsets. Headsets are being used to bring the jurors into the scene or replicate the medical condition of the plaintiff.

The next level in cardiac imaging is the full integration of digital and physical reality by using extended reality technology.47 The span of this technology ranges from an overlay of virtual objects on the real-world environment in “augmented reality” to an entire digital replacement with the option to substitute or remove physical information as well as to add digital information in “virtual reality”. The technical feasibility of creating real-time interactive 3D digital holograms in a standard catheterization laboratory has already been demonstrated.48 Furthermore, artificial intelligence technology is making its way into routine use to create dynamic valve models and enhance the diagnostic performance of current imaging tools.49

Other non-invasive imaging techniques which may become increasingly adopted are ECGI and Holographic imaging systems. ECGI allows an assessment of tissue characterization and can be used to locate areas exhibiting late electrical activation. Refinement of body surface mapping systems now means that instead of multiple electrode vests, a more straightforward ECG belt [154] can derive information on local electrical delay in order to guide LV lead implantation. Holographic imaging systems like the Holoscope (Real View Imaging, Yokneam, Israel) allow users to interact directly with a live 3D digital hologram. Physicians can manipulate the image (rotating, slicing, measuring, and marking) [155] fostering a greater understanding of the patients own unique anatomy.

Another interesting HI development are augmented reality (AR)-based headsets. AR-based headsets enable projection of multidimensional full-color holograms superimposed on the real world using holographic lenses. An advanced sensor system maps the environment around the user to anchor the holograms to the real world. Using voice commands and hand gestures AR-based headsets are very suitable to be introduced into the catheterization theatre. Potentially providing the cardiologist with additional 3D anatomical information and direct guidance projected on the patient.50 Besides HI, there is an increased use of 3D printing of cardiac structures for pre-procedural interventional treatment planning.51
