“…Kerrien et al [19] proposed a fully automated 3D-2D subtraction angiography registration method. This method compares the 2D angiographic image with the Maximum Intensity Projection (MIP) of the 3D angiographic volume [20] in two ways, firstly, by maximizing the intercorrelation information of the two images for a wide range of registration, and then by recovering the rigid body motion of the remaining part using an improved optical flow technique [21], and the registration effect of this method is shown in Figure 3. This method can effectively solve the problem of translation and rotation errors arising from matching the 3D vascular skeleton projection with the 2D skeleton extracted by DSA.…”

The registration of preoperative three-dimensional (3D) medical images with intraoperative two-dimensional (2D) data is a key technology for image-guided radiotherapy, minimally invasive surgery, and interventional procedures. In this paper, we review 3D-2D registration methods using computed tomography (CT) and magnetic resonance imaging (MRI) as preoperative 3D images and ultrasound, X-ray, and visible light images as intraoperative 2D images. The 3D-2D registration techniques are classified into intensity-based, structure-based, and gradient-based according to the different registration features. In addition, we investigated the different application scenarios of this registration technology in medical clinical treatment, which can be divided into disease diagnosis, surgical guidance and postoperative evaluation, and also investigated the evaluation method of 3D-2D registration effect.

Thirteen novel isatin-ampyrone Schiff bases derivatives were synthesized in only two steps of 70%-90% overall yields. In vitro cytotoxic activity of these new Schiff bases against three human tumor cell lines (MCF-7, A549, and SCOV3) as well as normal breast cell line (MCF-10A) were evaluated by MTT assay. Structure-activity relationship of the tested compounds revealed that chlorine group at C-5 position of the isatin ring significantly increased the cytotoxic activity. This study generally led to introduce a highly active molecule (M 12 ) with IC 50 values of 5.12, 25.5, and 12.9 μΜ, on MCF-7, A549, and SCOV3, respectively. Furthermore, molecular docking studies of the synthesized compounds were also done to investigate their binding modes towards VEGFR-2 and JNK3-MAP kinase as the main targets for isatin-containing anticancer agents. Binding free energy values of the compounds showed positive correlation with their cytotoxic activities. To confirm the docking results, molecular docking simulations of potent compound (M 12 ) against VEGFR-2 and JNK3 MAP kinase were also performed. According to the cytotoxic results and in silico ADMET predictions together, M 12 can be considered as a potent candidate for the future anticancer studies.

The Type 4 hydrogen storage tank has an internal liner made of polymer material. Instead of the joining of two cylinder-shaped liners through butt-joint thermal fusion bonding, a faster joining can be achieved through lap-joint laser welding. Non-destructive testing is required to inspect the quality of laser-welded areas and to detect pore defects. In this study, the interface of a laser-welded region is investigated using optical coherence tomography to detect internal pore defects, where the maximum thickness of the liner is found to be approximately 3 mm. Optical coherence tomography images with defects are then used for supervised YOLOv2 deep learning. Real-time detection of internal defects is successfully performed on laser-welded liner samples.
