Over the past thirty years, a number of researchers have investigated on 3D organ reconstruction from medical images and there are a few 3D reconstruction software available on the market. However, not many researcheshave focused on3D reconstruction of breast cancer’s tumours. Due to the method complexity, most 3D breast cancer’s tumours reconstruction were done based on MRI slices dataeven though mammogram is the current clinical practice for breast cancer screening. Therefore, this research will investigate the process of creating a method that will be able to reconstruct 3D breast cancer’s tumours from mammograms effectively.  Several steps were proposed for this research which includes data acquisition, volume reconstruction, andvolume rendering. The expected output from this research is the 3D breast cancer’s tumours model that is generated from correctly registered mammograms. The main purpose of this research is to come up with a 3D reconstruction method that can produce good breast cancer model from mammograms while using minimal computational cost.

Objectives Routine imaging modalities combined with state-of-the-art reconstruction software can substantially improve preoperative planning and simplify complex procedure by enhancing the surgeon’s knowledge of the patient’s specific anatomy. The aim of the current study was to demonstrate the feasibility of interactive three-dimensional (3D) computed tomography (CT) reconstructions for preoperative planning and intraoperative guiding in video-assisted thoracoscopic lung surgery (VATS) with 3D vision. Methods Twenty-five consecutive patients referred for an anatomic pulmonary resection by a single surgeon were included. Data were collected prospectively. All patients underwent a CT angiography in the diagnostic pathway prior to referral. 3D reconstruction of the pulmonary anatomy was obtained from CT scans with dedicated software. An interactive PDF file of the 3D reconstruction with virtual resection was created, in which all the pulmonary structures could be individually selected. Furthermore, the reconstructions were used for intraoperative guiding on double monitor during VATS with 3D vision. Results In total, 26 procedures were performed for 5 benign and 21 malignant conditions. Lobectomy and segmentectomy were performed in 20 (76.9 %) and 6 (23.1%) cases, respectively. In all patients, preoperative 3D reconstruction of pulmonary vessels corresponded with the intraoperative findings. Reconstructions revealed anatomic variations in 4 (15.4%) patients. No conversion to thoracotomy or in-hospital mortality occurred. Conclusions Preoperative planning with interactive 3D CT reconstruction is a useful method to enhance the surgeon’s knowledge of the patient’s specific anatomy and to reveal anatomic variations. Intraoperative 3D guiding in VATS with 3D vision is feasible and could contribute to the safety and accuracy of anatomic resection.

In this paper we present a simple stand-alone system performing the autonomous acquisition of multiple pictures all around large objects, i.e., objects that are too big to be photographed from any side just with a camera held by hand. In this approach, a camera carried by a drone (an off-the-shelf quadcopter) is employed to carry out the acquisition of an image sequence representing a valid dataset for the 3D reconstruction of the captured scene. Both the drone flight and the choice of the viewpoints for shooting a picture are automatically controlled by the developed application, which runs on a tablet wirelessly connected to the drone, and controls the entire process in real time. The system and the acquisition workflow have been conceived with the aim to keep the user intervention minimal and as simple as possible, requiring no particular skill to the user. The system has been experimentally tested on several subjects of different shapes and sizes, showing the ability to follow the requested trajectory with good robustness against any flight perturbations. The collected images are provided to a scene reconstruction software, which generates a 3D model of the acquired subject. The quality of the obtained reconstructions, in terms of accuracy and richness of details, have proved the reliability and efficacy of the proposed system.

The virtual human plan has been the hot point of recent research. The objective of this study is to explore the possibility of three-dimensional (3D) reconstruction of functional fascicular groups inside short segmental peripheral nerve. A 5 cm length of common peroneal nerve was horizontally sliced at 0.25 mm intervals, and each section was stained with acetycholinesterase histochemical staining. The 2D panorama images were acquired by high-resolution digital camera under 100 x microscope and mosaic software; different functional fascicular groups were distinguished and marked. The topographic database was then matched using image processing software, through the 3D reconstruction achieved using 3D reconstruction software (Amira 3.1). The reconstructed 3D images could be rotated or zoomed in any direction and the intercross and recombination processes of nerve bundles could be observed. Based on the serial histological sections and computer technology, the 3D microstructure of short segmental peripheral nerve functional fascicular groups was reconstructed. These results provide the possibility of 3D reconstruction of long segmental peripheral nerve functional fascicular groups.

<p><strong>Abstract.</strong> This paper presents an investigation as to whether and how the selection of the SfM-MVS software affects the 3D reconstruction of submerged archaeological sites. Specifically, Agisoft Photoscan, VisualSFM, SURE, 3D Zephyr and Reality Capture software were used and evaluated according to their performance in 3D reconstruction using specific metrics over the reconstructed underwater scenes. It must be clarified that the scope of this study is not to evaluate specific algorithms or steps that the various software use, but to evaluate the final results and specifically the generated 3D point clouds. To address the above research issues, a dataset from the ancient shipwreck, laying at 45 meters below sea level, is used. The dataset is composed of 19 images having very small camera to object distance (1 meter), and 42 images with higher camera to object distance (3 meters) images. Using a common bundle adjustment for all 61 images, a reference point cloud resulted from the lower dataset is used to compare it with the point clouds of the higher dataset generated using the different photogrammetric packages. Following that, a comparison regarding the number of total points, cloud to cloud distances, surface roughness, surface density and a combined 3D metric was done to evaluate and see which one performed the best.</p>

Abstract. The creation of three-dimensional models for the cataloguing and documentation of cultural heritage is today an emerging need in the cultural sphere and, above all, for museums. The cultural heritage is still catalogued and documented based on descriptive files assorted of photographic images which, however, fail to outline its spatial richness, possible only through the use of 3D artefacts. The essay aims to propose a methodology of digitalization by low-cost and easy-to-use systems, to be employed even by non-expert survey and photogrammetry’s operators. The case study of the statue of San Nicola da Tolentino, preserved at the Sant’Agostino complex in Bergamo, offered the possibility of a comparison between 3D models acquired with different digitalization tools (professional/action/amateur cameras and smartphone) and processed by several image-based 3D Reconstruction software and methods.
