Providing prevention, diagnosis, and treatment of patients after COVID-19 using artificial intelligence.

Objective: The aim of this research was to investigate the prevention, diagnosis, and treatment of patients after COVID-19 with the possibility of using artificial intelligence and virtual reality in combination with traditional approaches to patient rehabilitation.

Materials And Methods: Statistical methods were used to evaluate the situation of COVID-19 worldwide and in Slovakia until March 2022. We investigated the rehabilitation options of breathing exercises, upper and lower limb rehabilitation, and cognitive tasks in patients with post-COVID syndrome who met the criteria for a combined rehabilitation program using virtual reality.

Possible consequences of Covid-19 on the nervous system.

Objectives: The aim of the survey was to find out what the possible consequences are of the COVID-19 disease on the nervous system and to propose a method of using artificial intelligence.

Material And Methods: Recent research has shown that the risks to patients due to severe acute coronavirus 2 respiratory syndrome (SARS-COV-2) differ most significantly depending on age and the presence of underlying comorbidities such as: cardiovascular disease, hypertension, diabetes and others. The consequences of COVID-19 on the nervous system are especially important.

Combined methods of rehabilitation of patients after stroke: virtual reality and traditional approach.

Objectives: The aim of the research was to verify the possibilities of using virtual reality in combination with classical approaches to the rehabilitation of patients after stroke.

Material And Methods: As part of rehabilitation, we examined the possibilities of rehabilitation of the upper, lower limbs and fine mobility of the upper limbs in a selected group of patients that met the criteria for inclusion in a combined rehabilitation program using virtual reality with a focus on testing different approaches, devices and applications. At the same time, we tried to identify quantitative and qualitative parameters that could be objectively measured and based on them to evaluate the progress of patients in rehabilitation or in personalizing individual rehabilitation scenarios.

Computerized brain atlas in functional neurosurgery.

Computerized brain atlas is a new application area in the practical use of stereotactic neurosurgery. Our approach provides a solution for the straightforward definition of a coordinate system (CA-CP), localization of the selected target point, trepanation points and trajectory transformation of the stereotactic electrode or canula for functional neurosurgery. These problems were solved by comparison of CT, MR and the Schaltenbrand-Wahren atlas.

Combination warp-matching method for stereotactic neurosurgery.

Digital image warping is a growing branch of image processing that deals with geometric transformation techniques. A geometric transformation is an operating that redefines the spatial relationship between points in an image. Physically based modeling is a field strongly attracting research interest in recent years.

Mathematical methods using CT and MR images for stereotactic neurosurgery.

A new application area in the practical usage of magnetic resonance imaging (MRI) has been identified as a methodology of stereotactic operation. In particular, our approach provides a solution for the straightforward definition of target and trepanation points for the purposes of stereotactic neurosurgical operation, and an exact testing of its result. The definition of the proper transformation between different examination data sets is a crucial mathematical problem.

MR-guided stereotaxy in functional neurosurgery.

MR imaging enables the localization of the anteroposterior commissural line, but sometimes it is difficult to define the anterior commissure point. The corpus callosum is more easily identified in this case. We performed an MR imaging using the following methodology; a single transverse scan from which a coronal scan is planned with compensation.

[CT and MR imaging in stereotaxic neurosurgery].

The combination of CT and MR examinations indicates a specific approach to the treatment of brain mass lesions. CT guided stereotaxy is sufficient for well demarcated tumors, haemorrhages and abscesses. MR guided stereotaxy is necessary to be performed in invasively growing brain tumors where explicit histological verification and localisation must be ascertained.

Transformation of computed tomography and magnetic resonance images.

This paper discusses the transformation of computed tomography (CT) and magnetic resonance (MR) images, which maps the stereotactic volumetric cube of one examination to another. There are some mathematical problems connected with the present method. This approach provides a better visual detection and localization of the target point for the neurosurgeon or radiologist.

Stereotactic technique and pathophysiological mechanisms of neurotransplantation in Huntington's chorea.

In Huntington's chorea, embryonal brain tissue (striatum) was implanted in the caudate nucleus bilaterally, using stereotaxy assisted by CT. A special cannula allowed the placement into the brain of 3 or 4 grafts of embryonal tissue along the determined trajectory by one introduction of the cannula. The pathophysiological mechanism of neurotransplantation in Huntington's chorea is to compensate for the degenerated striatal tissue by embryonal striatum, so it is necessary to supply a quantity of embryonal striatal tissue which enables the whole functional integrity.
