“…In case of active fetal movements, volume can be acquired using the 3D live mode (4D) facility rather than using the static 3D mode. This option has demonstrated its clinical value when reconstructing the fetal face 5 and/or the cardiac structures using the spatio-temporal-image correlation (STIC) technique [6][7][8][9] . Tonni et al 5 have demonstrated that 3DUS have enhanced the diagnostic accuracy in detecting cleft lip (CL) and cleft palate (CP) in a routine second trimester scan on low-risk pregnant women.…”

Since the introduction of sonography into clinical practice, two-dimensional ultrasound (2DUS) has represented the standard application in obstetrics care. Nonetheless, technological advancement has brought to healthcare givers a new opportunity that is three-dimensional ultrasound (3DUS). Are there nowadays convincing evidence that 3DUS offer advantages over 2DUS and have gained recognized as well as well established role to justify its inclusion into routine obstetrics practice? The technological advancement reached by 3DUS warrant appropriate operator training program in order to acquire expertise to manage ultrasound applications and software. When this "goal" is reached, there is no doubt concerning the fact that one of the main advantages of 3DUS over 2DUS is represented by anatomic acquisition of a volume. Once a volume data set has been acquired, it can be sectioned on-line or transferred to an external personal computer for post-processing analysis. At this stage, "navigation" within the volume is possible, and operators can then freely sectioned or rendered the volume on-demand. This is of dramatic importance in teaching and training clinical setting. Furthermore, volume can be acquired on standardized plane at remote site even by inexperienced operator in 3DUS and send for expert consultation using telemedicine. Although stored volume data sets are large, up to 10 megabyte, they can be compressed to about 15 to 20% of the original file size and submitted via Digital Imaging and Communications in Medicine (DICOM) technology for off-line consultation without noticeable loss of details or image quality 1 . Moreover, volume data sets can be shared by expert on dedicated website and be used in multicenter studies while demonstrating a high sensitivity and reliability 2,3 . 3DUS with its applications allow operators a simultaneous and less time consuming (when compared with 2DUS) rendering of the anatomical landmarks in three orthogonal planes when using the multiplanar mode. In such case, the region of interest is displayed on the upper left quadrant on the ultrasound video equipment while the sagittal plane, the coronal and the axial are rendered in plane A, plane B and plane C, respectively. The planes obtained from the 3D volume are parallel and not oblique or at an angle, as is the case with conventional 2DUS. In addition, when comparing 2DUS vs. 3DUS studies of pathological cases, one of the most important advantages offered by "navigating" inside the volumes generated by 3DUS is the ability to follow the green "reference" dot that indicates the

“…In many centres, 3D ( Figure 5) and 4D (real-time) ultrasonography has superseded traditional 2D technology, although the sensitivity and specificity of newer technologies for cleft lip and palate diagnosis are broadly similar. 15 A positive antenatal diagnosis can be a difficult time for many parents, with the joy and excitement of parenthood being tinged by feelings of shock, stress, anxiety and guilt that the cleft has somehow been their fault. The first questions parents ask at this stage are:  What caused the cleft?…”

Management of patients with non-syndromic clefts of the lip and/or palate part 1: from antenatal diagnosis to primary surgery

Patients with clefts of the lip and/or palate require input from a diverse group of medical, surgical, dental and parasurgical specialties working as part of a multidisciplinary team in the UK. Co-ordinated care ensures that the patient receives optimal treatment whilst minimizing the burden of care for the NHS and family. The primary care dentist has an important role in the overall management of patients with clefts. Because the dentist-patient/parent relationship is of a long-term nature, the primary care dentist can also provide useful support and advice for families as they progress through the care pathway. This three-part article will illustrate the integration of dentistry with the other aspects of care. Clinical Relevance: Dentists should be aware of the different types of cleft lip and/or palate that occur and the role of the dentist in the overall management of patients who have clefts.

“…Then, the gray-levels of the phantoms' faces should be between the gray-levels for real fetal faces and real fetal skulls in 3D US images, while gray-levels for the phantoms and real fetal faces could be close to each other. Actually, by visually comparing US images for our phantoms with real fetal faces [28] and skulls [29], it turns out that gray-levels for our phantoms and real fetal faces are almost identical, while real fetal skulls are brighter due to the larger reflection coefficient value (31.8%).…”

SUMMARYToward the actualization of an automatic navigation system for fetoscopic tracheal occlusion (FETO) surgery, this paper proposes a 3D ultrasound (US) calibration-based approach that can locate the fetal facial surface, oral cavity, and airways by a registration between a 3D fetal model and 3D US images. The proposed approach consists of an offline process and online process. The offline process first reconstructs the 3D fetal model with the anatomies of the oral cavity and airways. Then, a point-based 3D US calibration system based on real-time 3D US images, an electromagnetic (EM) tracking device, and a novel cones' phantom, computes the matrix that transforms the 3D US image space into the world coordinate system. In the online process, by scanning the mother's body with a 3D US probe, 3D US images containing the fetus are obtained. The fetal facial surface extracted from the 3D US images is registered to the 3D fetal model using an ICP-based (iterative closest point) algorithm and the calibration matrices, so that the fetal facial surface as well as the oral cavity and airways are located. The results indicate that the 3D US calibration system achieves an FRE (fiducial registration error) of 1.49±0.44 mm and a TRE (target registration error) of 1.81±0.56 mm by using 24 fiducial points from two US volumes. A mean TRE of 1.55±0.46 mm is also achieved for measuring location accuracy of the 3D fetal facial surface extracted from 3D US images by 14 target markers, and mean location errors of 2.51±0.47 mm and 3.04±0.59 mm are achieved for indirectly measuring location accuracy of the pharynx and the entrance of the trachea, respectively, which satisfy the requirement of the FETO surgery. key words: 3D location, fetal oral cavity and airways, 3D ultrasound calibration, iterative closest point algorithm, 3D fetal model, 3D electromagnetic tracking device
