Although the photon yield is relatively low, the high level of activity administered makes quantitative gamma camera imaging of 177Lu possible [21, 22].
In summary, serum, tumour and normal tissue enzyme levels could be monitored by direct measurement on tissue samples and by serial quantitative gamma camera imaging of radiolabelled antibody-enzyme conjugate.
In addition to high-energy beta-radiation, 166Ho emits gamma radiation that allows gamma camera quantitative imaging and dosimetry [10, 11].
All additional images were obtained with a Zeiss Axioplan 2 Imaging microscope using a Retiga 1350EX camera (Quantitative Imaging Corporation, Surrey, BC, Canada) with Northern Eclipse software (Empix Imaging, Mississaga, ON, Canada).
This section first presents the created models and then presents a quantitative analysis of the camera pose estimation.
The absolute quantitative accuracy of gamma camera SPECT quantification has typically been reported to be within 20% for a range of radionuclides [2, 4].
Instead, quantitative monitoring of the camera count rate during routine QC or less careful calibration source acquisition using a planar acquisition could be performed for each patient or each morning to check for large changes in the camera sensitivity and as an indicator that recalibration is needed.
In addition, we demonstrate that in vivo imaging with a CCD camera is quantitative and a more reproducible measurement of transgene expression than ex vivo measurement, which requires animal sacrifice during the experiment.
The vestibular clinical examination (spontaneous nystagmus, positional maneuvers, head shaking test) was performed by means of quantitative VNG with a camera connected to a software analyzing the data (EDM, Euroclinic, Italy).
Quantitative evaluation of range cameras requires scenes with ground truth distance measurements.
