Fig. 7From: Multimodality calibration for simultaneous fluoroscopic and nuclear imagingMontage of frames from a simultaneous hybrid acquisition (Additional file 1) of two syringes connected via a three-way valve filled with 49Â MBq of 99mTc showing fluoroscopic images in grayscale and nuclear images in color overlay. Images were obtained with a parameter set acquired by physical measurement (a) and with a parameter set acquired by the calibration method (b)Back to article page
