which may include new or worsened ischaemia presenting as wall-motion abnormalities, and is crucial in the diagnosis of coronary artery diseases 36 . Furthermore, subjects with heart failure may sometimes seem asymptomatic at rest, as the heart sacrifices its efficiency to maintain the ...
Materials and methods To provide such information during the procedure, a novel surgical assistance system for open heart bypass graft surgery was designed which merges preoperative maps of the coronary arteries with intraoperative data. The patient-specific vessel map was generated from multi-slice ...
In total, 90 consecutive clinical coronary CT angiography examinations with heart rate > 75 bpm were evaluated. Table 1 describes the clinical characteristics of the 90 patients in this study. The mean patient age was 61.5 years ± 8.4; 44 of the 90 patients (48.9%) were men. The...
In recent years, transcatheter aortic valve replacement (TAVR) has become the leading method for treating aortic stenosis. While the procedure has improved dramatically in the past decade, there are still uncertainties about the impact of TAVR on coronar
tissue movement such as breathing,peristalsis,bladder filling, heartbeat, or other involuntary motion. This further translates to greater mismatch and complexity as the number and distance between regions of interest increases. For example, when using a rigid technique, it is easier to register to ...
Planarity. Planarity for the three artery locations (PV, DV, and SB) of the LMCA and LAD bifurcations were all directed toward the heart and of similar magni- tude (LMCAbif: PV ¼ À5.50, DV ¼ À5.14, SB ¼ À4.36; LADbif: PV ¼ À1.16, DV ¼ À2.09, SB ¼ ...
10 ms) than the conventional SR method (∼1-5 mins), with comparable spatial resolution and 1.5-dB higher contrast-to-noise ratio (CNR). Besides, the proposed method with single PW can achieve higher CNR than DAS with 75 PWs in reconstruction ofin-vivoimages of human carotid arteries....
The diagnosing areas also include spinal/tendon injuries, ligament tears chest, and abdomen (heart, liver, kidney, and spleen) [44]. For medical image fusion, there are intensive applications on different human organs where the impact of MRI takes place. These applications include prostate studies...
the second medical image of the subject comprising the one or more regions of the one or more coronary arteries of the subject; identify the one or more regions of the one or more coronary arteries of the subject from the first medical image in the second medical image; analyze the second...
it is necessary to introduce the contrast material directly to the heart arteries by coronary catheterization, a highly invasive procedure involving the insertion of a catheter tube through the patient's arteries. While effective, this procedure is generally undesirable because of the risks that it im...
