... imaging techniques ( Fig. 1) are a crucial method to examine the inside of the body without making a surgical incision. Imaging is no longer only used for medical diagnosis, but is increasingly vital for image-guided therapies. Moreover, cutting-edge imaging methods are being used to investigate systemic activities including flow rates, oxygen concentrations, and ...

... with the following iodine concentrations were prepared using standard iodine solutions and distilled water in the following ratios: 1:0, 3:1, 2:2, and 1:3. As indicated in (Fig. 9), we obtained various spectra and compared them to the background spectrum. We can determine iodine edge in every concentration by eliminating background as shown in (Fig. 10). By taking the integration of each edge and drawing a relationship between the value of integration and concentration, we ensured that the detector was effective in differentiating between iodine concentrations. The curve must be a straight line as shown in (Fig. 11), but small variations may occur due to sample preparation conditions. ...

... relationship between The time-over-threshold (TOT) and different foil thicknesses. With increased Al foil thickness, cluster and pixel counts decreased. The most TOT was absorbed by pixels 1 and 2 when an Al foil wasn't used. While using an Al foil with a 16 mm thickness, the TOT absorption was divided throughout various pixels as illustrated in (Fig. 14). ...

... studied the characteristics of a GaAs pixel detector using a variety of currents to determine the most effective currents for GaAs pixel performance. Subsequently, we determined the number of clusters with increased current, as shown in (Fig. 15). Thus, we investigated the relationship between TOT and various currents ranging from 10 µA to 150 µ A. When an Al filter with a 4mm thickness was used, pixels one and two absorb the most TOT at the current 150 µA. ...

... another significant aspect of a GaAs detector that can be studied in this regard is the number of pixels in a cluster. Increasing the bias voltage can result in an increase in the number of pixels in a cluster because a stronger electric field can improve charge collection and reduce charge sharing between neighboring pixels, as shown in Figure 19(b), at which high voltage we find clusters that contain 6 pixels, but generally the count of clusters that contain 6 pixels is lower than that of clusters that contain more pixels as shown in (Fig. 16). ...
