Abstract Stereotactic radiosurgery (SRS) is one of the surgical alternatives for drug-resistant essential tremor (ET). Here, we aimed at evaluating whether biologically effective dose (BED Gy2.47 ) relevant improvement after stereotactic radiosurgical thalamotomy in a population patients treated with (unplugged) isocenter and uniform 130 Gy. This retrospective longitudinal single center study. Seventy-eight consecutive were clinically analyzed. Mean age was 69.1 years (median 71, range...
A comparison was made between the image quality of a photon-counting CT (PCCT) and dual-source (DSCT). The evaluation performed using Catphan phantom, physical metrics, such as noise power spectrum task transfer function, were measured for both PCCT DSCT at three dose indices (1, 5 10 mGy). Polyenergetic virtual monoenergetic reconstructions used to evaluate performance differences by simulating Gaussian spot with radius mm calculating detectability index. highest iterative reconstruction...
The new Leksell Gamma knife convolution algorithm requires evaluation prior to implementation in clinical practice. superiority of this algorithm, which takes into account tissue electron densities, was evaluated using EBT3 GafChromicTM films within an anthropomorphic phantom. CIRS head phantom chosen for its relevance validate the algorithm. Absolute dose and distributions were measured compared with outputs calculated from Plan algorithms (TMR10 algorithm). absolute homogeneous region...
