The TIPS procedure is an endovascular operation guided by biplane fluoroscopy. The goal is to pass a needle from the hepatic vein through the liver into the portal vein. We are developing a software for real-time, 3D guidance of the procedure. This paper discusses means of automatically defining the needle from biplane fluoroscopic views.

INTRODUCTION Cardiovascular magnetic resonance (CMR) allows very accurate, but time-consuming, volume assessment by the short-axis slice summation technique. The single and biplane methods of volume assessment are used less, partly because FLASH cine imaging provides poor blood-myocardium contrast in long-axis views. TrueFISP gives excellent blood-myocardium contrast, even in patients with hear...

background:   hallux valgus deformity is a common chronic problem in middle age and elderly. different surgical procedures have been introduced so far with their proposed indications for each. this study aimed to compare three   current procedures namely chevron osteotomy, scarf osteotomy and mcbride technique.     methods:   in this study, 44 patients were included from 2010 to 2013. all patie...

i ntroduction:   the  trigeminocardiac  reflex  (tcr)  refers  to  the  sudden development of bradycardia as well as asystole along with arterial hypotension associated with any manipulation of sensory branches of the trigeminal nerve. clinically, the tcr has been reported to occur during craniofacial surgery. it is crucial to learn about this sudden physiological response during maxillofacial ...

Simultaneous biplane left ventriculography was performed in 59 patients with ischaemic heart disease. A comparison was made of the frontal (EFF), lateral (EFL), and biplane (EFB) ejection fractions. Discrepancies between the three measurements in the same patient were frequent observed. The patients were then grouped according to the presence or absence of signs of transmural myocardial infarct...

Femoral osteotomy is performed for osteonecrosis of the femoral head to prevent progression collapse and promote repair process by transposing necrotic lesion nonweight-bearing portion. The purpose this review article was summarize current knowledge on two types osteotomy: transtrochanteric anterior or posterior rotational curved varus osteotomy, both which are currently osteonecrosis, mainly i...

Aims To determine whether left ventricular volumes and ejection fractions calculated from single plane two-dimensional echocardiograms using the algorithm (0·85AL) correlate with those calculated using the biplane Simpson’s method, and whether small changes in volumes and ejection fraction occurring post-infarction could be detected from single-plane as well as from biplane two-dimensional echo...
