In this paper, we propose a novel method to generate panoramic X-ray images intra-operatively by using the previously introduced camera augmented mobile C-arm by Navab et al. [1]. This advanced mobile C-arm system acquires registered X-ray and optical images by construction, which facilitates the generation of panoramic X-ray images based on the motion estimation of the X-ray source. Visual mar...

The recent publication of a number of high resolution bacterial voltage-gated sodium channel structures has opened the door for the mechanisms employed by these channels to distinguish between ions to be elucidated. The way these channels select between Na(+) and K(+) has been investigated in computational studies, but the selectivity for Na(+) over Ca(2+) has not yet been studied in this way. ...

3D reconstruction of arterial vessels from planar radiographs obtained form multitude of angles around the object has gained increasing interest. The motivating application has been interventional angiography. In these procedures data acquisition, visualization, decision making, and the action are all incorporated in one loop that is time critical. This project encompasses an entire workflow; f...

Sodium channels are voltage-gated sodium-selective ion present in the membrane of most excitable cells. comprise one pore-forming α subunit, which may be associated with either or two β subunits [179]. α-Subunits consist four homologous domains (I-IV), each containing six transmembrane segments (S1-S6) and a loop. The positively charged fourth segment (S4) acts as voltage sensor is involved cha...

BACKGROUND According to Beck theory, dysfunctional attitude has a central role in emergence of depression. The aim of this study was to determine contributions of dysfunctional attitude and general health index to depression. METHODS In this case-control study, two groups of subjects participated. The first group consisted of 65 patients with major depression and dysthymic disorder, who were ...

First flexible robotic intra-operative nuclear imaging for image-guided surgery José Gardiazabal tum.de Tobias Reichl tum.de Aslı Okur tum.de Tobias Lasser tum.de Nassir Navab tum.de Functional imaging systems for intra-operative use, like freehand SPECT, have been successfully demonstrated in the past, with remarkable results. These results, even though very positive in some cases, tend to suf...

Recently, Tuceryan and Navab introduced a method for calibrating an optical see-through system based on the alignment of a set of 2D markers on the display with a single point in the scene while not restricting the user’s head movements (the single point active alignment method or SPAAM in short) [33]. This method is applicable with any tracking system, provided that it gives the pose of the se...

Background: In this research a rapid vulnerability and risk assessment at territorial level is performed. Methods: The methodology used, initially proposed for ancient masonry churches, extended applied to ten historic mosques in Kermanshah city. method could be considered as preliminary approach of structures, refers LV0 method, since the used requires simple qualitative information. It involv...

Since the introduction of closed chest synchronized DC shock treatment for atrial fibrillation by Lown in 1962 (Lown, Amarasingham, and Newman, 1962a; Lown et al., 1962b) many thousands of patients have undergone this treatment. Complications have occurred on occasion. Arrhythmias, some fatal, have been reported by Ross (1964), Morris et al. (1964), Killip (1963), and Turner and Towers (1965). ...
