A miniature multi-detector gamma probe (12 CdTe) for ambulatory monitoring of the left ventricular function

Ambulatory monitoring of ventricular function parameters together with ECG data could help with the follow-up of patients with coronary disease [1,2]. This can be achieved by the continuous recording of the left ventricular volume curve, from which a number of important relevant parameters can be derived such as the left ventricular ejection fraction (LVEF). The LVEF is defined as the ratio of the ventricular blood ejected by the heart during its contraction (Vmax-Vmin/Vmax). Nuclear Medicine (NM) methods using the gamma camera are widely recognized as the "gold standard" for single LVEF measurements, but ambulatory monitoring requires miniaturized probes.
