The four-chamber view of heart plays an important role in clinical diagnosis of cardiac disease. According to the geometric structure of heart, we propose a method to automatic acquisition of the four-chamber view in volume data. First, the contrast-medium enhanced part of dual source CT data is segmented and morphological operations are applied. Second, the Dijkstra Algorithm considering 3D Euler Distance as weighting factor is introduced to extract the center line of atrium and ventricle. Finally, the four-chamber view of heart is estimated based on the 3D Euclidean Distance and the geometric characteristics of the center line. In this paper, 40 patients (age from 49 to 81) are examined, and the recognition rate is 91.25%.

Abstract Fetal cardiac screening is an obligation for everybody performing prenatal ultrasound. The heart, as a small and always moving object, is still the most difficult part of the fetal anatomy evaluation. Knowing this, different methods of improving antenatal screening for congenital heart defects (CHD) were introduced. Spatial temporal image correlation (STIC) is the newest one. Its target was to automatic acquisition of the fetal scan from the abdomen, through 4 chamber view toward the three vessel view and off-line analysis of the anatomy of the fetal cardiovascular system. Is that really possible? Does STIC improve screening of CHD? Would it be helpful in the more precise diagnosis of complicated heart defects? These are still the open questions, which will be discussed in the article.

ABSTRACT A 37 years old Thai pregnant woman with MCDA twins, para 1, was suspected of severe twin-twin transfusion syndrome (TTTS) at 21 weeks’ of gestation. Quintero staging was applied in this cases. Neither of the fetuses exhibited signs of hydrops. Abnormal four-chamber view was demonstrated in a recipient fetus. Two-dimensional and color Doppler showed complex cardiac malformations which include (1) hypoplastic left ventricle, and (2) large atrial septal defect, (3) atretic tricuspid valve, and (4) the blind right atrium communicating with the left atrium through the ostiumprimum defect. For more information, threedimensional (3D) echocardiography was used toreconstruct“thin slab” of the fetal heart and its outflow tracts. A double-outletright ventricle (DORV) was highly suspicious. Congenital cardiac anomaly can decompensate the compromised myocardium of the recipient fetus. In addition to conventional 2D echocardiography, the application of advanced 3D echocardiography with ‘thin slab’ technique can help for the examination of fetal heart.

3D echocardiography (3DE) will gain increasing acceptance as a routine clinical tool as the technology evolves due to advances in technology and computer processing power. Images obtained from 3DE provide more accurate assessment of complex cardiac anatomy and sophisticated functional mechanisms compared with conventional 2D echocardiography (2DE), and are comparable to those achieved with magnetic resonance imaging. Many of the limitations associated with the early iterations of 3DE prevented their widespread clinical application. However, recent significant improvements in transducer and post-processing software technologies have addressed many of these issues. Furthermore, the most recent advances in the ability to image the entire heart in realtime and fully automated quantification have poised 3DE to become more ubiquitous in clinical routine. Realtime 3DE (RT3DE) systems offer further improvements in the diagnostic and treatment planning capabilities of cardiac ultrasound. Innovations such as the ability to acquire non-stitched, realtime, full-volume 3D images of the heart in a single heart cycle promise to overcome some of the current limitations of current RT3DE systems, which acquire images over four to seven cardiac cycles, with the need for gating and the potential for stitch artefacts.
