“…Figure 2 Third dataset comprised nine MR prostate images obtained from publicly available database of The Brigham and Women's Hospital [48]. This dataset has been extensively used for research on medical procedures [49,50]. Out of these images, one was randomly selected as the reference image and the rest eight were labeled as subject images.…”

This paper presents a novel method for 2D inter-subject non-rigid image registration. It is motivated by the ideas derived from elastodynamics which is the subclass of linear elastic theory. We propose to model the non-rigid deformations as elastic waves which are characterized by elastodynamics wave equation. Our registration method is formulated in a multi-resolution manner such that it is able to recover significant deformations. The proposed scheme recovers local (non-linear) as well as global deformations. The results of image registration by the proposed technique were validated via similarity measures for real MR brain images, BrainWeb dataset and MR prostate images. We have also used overlap measures (Jaccard distance, Dice coefficient and Overlap coefficient) over the segmented deep-brain structures including: lateral and third ventricles, putamen and caudate nucleus for real image dataset to further validate our proposed registration scheme. The proposed scheme was also compared with demons, Level set and free-form deformations (cubic B-spline) algorithms implemented in ITK toolkit and symmetric normalization method available in ANTs software package. Our proposed algorithm shows marked improvement of the inter-subject non-rigid registration, both qualitatively and quantitatively, over the four above-mentioned methods. This comparison was performed on all the three types of datasets mentioned above. 2D synthetic experiments comprising of Patch-'C', Square-Rectangle and Circle-'C' were also performed with our algorithm and compared with other four methods. Both qualitative and quantitative results B Sahar Ahmad Pakistan show that our method performs better than the other four methods. Results suggest that our proposed algorithm has improved accuracy over lemons, level set and free-form deformations (ITK implemented) and symmetric normalization method (ANTs based), tested over two types of brain and one prostate MRI. The commonly used synthetic experiments also suggest the superiority of our proposed scheme.

“…14 Recently, they reported the performance of robotically assisted needle guide placement using transperineal MR-GB and compared that method with the manual placement through the template guide. 15 The robotic device used in this study applied a motorized template to guide the needle with a control resolution of 0.001 mm. The investigators used 3DSlicer (this is the name of open source software http://www.slicer.org/) software for motion control of the robotic device and to optimize the needle placement.…”

“…In particular, systems for breast [75] and prostate interventions [76] that allow precise puncture on the basis of MRI images acquired during the intervention are widely used. After suitable registration of the target unit, the needle trajectory is calculated directly from a graphically marked MRI position in some systems [77].…”

ABSTR AC TBackground MRI is attractive for the guiding and monitoring of interventional procedures due to its high intrinsic soft tissue contrast and the possibility to measure physiologic parameters like flow and cardiac function.Method The current status of interventional MRI for the clinical routine was analyzed.Results The effort needed for the development of MR-safe monitoring systems and instruments initially resulted in the application of interventional MRI only for procedures that could not be performed by other means. Accordingly, biopsy of lesions in the breast, which are not detectable by other modalities, has been performed under MRI guidance for decades. Currently, biopsies of the prostate under MRI guidance are established in a similar fashion. At many sites blind biopsy has already been replaced by MR-guided biopsy or at least by the fusion of MR images with ultrasound. Cardiovascular This document was downloaded for personal use only. Unauthorized distribution is strictly prohibited.interventions are performed at several centers for ablation as a treatment for atrial fibrillation. Conclusion IntroductionMRI has an intrinsically high soft-tissue contrast and can be used to measure physiological parameters, such as blood flow (flow rate and flow volume), diffusion, temperature, and movement. Since its introduction into the clinical routine in the 1980 s, it has also been used for guiding and monitoring interventions. However, in contrast to CT and ultrasound, the use of MRI for guiding interventions requires significant technical effort. Due to the disruptive effect of the strong main magnetic field and the alternating electromagnetic fields, the monitoring of patients during an intervention by measuring ECG signals, oxygen saturation, or blood pressure requires special equipment. These monitoring systems must not interfere with the MRI scan and must be MR-safe (according to DIN EN 62 570:2010 -05). The list of requirements regarding monitoring equipment provides an indication of the development effort, with suitable monitoring equipment representing only one of the components necessary for MR-guided interventions.In addition to MRI safety, all catheters and instruments must be adapted to this modality. To ensure MRI safety, metal must be largely avoided since, depending on the length and orientation to the main magnetic field, it can heat up and consequently even result in burns. Achieving rigidity and torsion stability of catheters or guide wires without the use of metal for reinforcement represents a technical challenge. In the case of needles, breaking resistance is one of the more difficult properties to achieve for MR-safe designs. Moreover, instruments must be able to be effectively visualized without adjacent structures being superimposed by artifacts. The tip must be able to be identified and definitively differentiated from the shaft since MRI as a cross-sectional imaging method typically uses individual slices even for guiding interventions and does not use projections as in fluoroscopy...
