Deep brain stimulation (DBS) therapy requires extensive patient-specific planning prior to implantation achieve optimal clinical outcomes. Collective analysis of patient's images is promising in order provide more systematic assistance. In this paper the design a normalization pipeline using group specific multi-modality iterative template creation process presented. The focus was compare performance selection freely available registration tools and select best combination. workflow applied...
The success of deep brain stimulation (DBS) relies primarily on the localization implanted electrode. Its final position can be chosen based results intraoperative microelectrode recording (MER) and tests. optimal often differs from one selected for chronic with DBS aim study was to investigate, using finite element method (FEM) modeling simulations, whether lead design, electrical setup, operating modes induce differences in electric field (EF) distribution consequence, clinical outcome....
Abstract Deep brain stimulation (DBS) is an established therapy for movement disorders such as essential tremor (ET). Positioning of the DBS lead in patient’s crucial effective treatment. Extensive evaluations improvement and adverse effects at different positions various current amplitudes are performed intraoperatively. However, to choose optimal position lead, information has be “mentally” visualized analyzed. This paper introduces a new technique called “stimulation maps,” which...
This paper presents a study on the influence of strong magnetic field NMOS transistors' electrical characteristics. Experiments have been carried out in small animal 7T MRI scanner, and shown that up to exists but remains manageable. It is demonstrated it depends transistor size, orientation chip inside field, gate-to-source voltage. A theoretical analysis good agreement with experiments has developed. Extrapolation ultra-high i.e. above 10T, shows at such may be challenging, can lowered by...
Group analysis of patients with deep brain stimulation (DBS) has the potential to help understand and optimize treatment movement disorders. Probabilistic maps (PSM) are commonly used analyze correlation between tissue symptomatic effect but applied different methodological variations.To compute a group-specific MRI template PSMs for investigating impact PSM model parameters.Improvement occurrence dizziness in 68 essential tremor implanted caudal zona incerta were analyzed. The input data...
In this paper, we show that B-spline quarks and the associated quarklets fit into theory of biorthogonal multiwavelets. Quark vectors are used to define sequences subspaces [Formula: see text] which fulfill almost all conditions a multiresolution analysis. Under some special on parameters, they even satisfy those properties. Moreover, prove possess modulation matrices perfect reconstruction condition. Furthermore, existence generalized dual known be at least compactly supported tempered...
This paper presents a tracking system using magnetometers, possibly integrable in deep brain stimulation (DBS) electrode. DBS is treatment for movement disorders where the position of implant prime importance. Positioning challenges during surgery could be addressed thanks to magnetic tracking. The proposed this paper, complementary existing procedures, has been designed bridge preoperative clinical imaging with surgery, allowing surgeon increase his/her control on implantation trajectory....
Abstract Deep brain stimulation (DBS) is a therapy for Parkinson’s disease (PD) and essential tremor (ET). The mechanism of action DBS still incompletely understood. Retrospective group analysis intra-operative data recorded from ET patients implanted in the ventral intermediate nucleus thalamus (Vim) rare. Intra-operative tests generate rich their use has not yet been explored. Objective. To implement, evaluate, apply workflow to probabilistic maps (PSMs) using Vim. Approach. A...
Neuroscience studies entail the generation of massive collections heterogeneous data (e.g. demographics, clinical records, medical images). Integration and analysis such in research centers is pivotal for elucidating disease mechanisms improving outcomes. However, collection clinics often relies on non-standardized methods, as paper-based documentation. Moreover, diverse types are collected different departments hindering efficient organization, secure sharing compliance to FAIR (Findable,...
Abstract This paper is concerned with near-optimal approximation of a given univariate function elements polynomially enriched wavelet frame, so-called quarklet frame. Inspired by hp -approximation techniques Binev, we use the underlying tree structure frame to derive an adaptive algorithm that, under standard assumptions concerning local errors, can be used create approximations error close best for cardinality. We support our findings numerical experiments demonstrating that this approach...
Deep brain stimulation (DBS) represents today a well-established treatment for movement disorders. Nevertheless the exact mechanism of action DBS remains incompletely known. During surgery, numerous tests are frequently performed in order to evaluate therapeutic and adverse effects before choosing optimal implantation site lead. Anatomical structures responsible induced have been investigated previously, but only based on data obtained with implanted The present study introduces methodology...
This paper is concerned with near-optimal approximation of a given function $f \in L_2([0,1])$ elements polynomially enriched wavelet frame, so-called quarklet frame. Inspired by $hp$-approximation techniques Binev, we use the underlying tree structure frame to derive an adaptive algorithm that, under standard assumptions concerning local errors, can be used create approximations error close best for cardinality. We support our findings numerical experiments demonstrating that this approach...
