Purpose

The twilite is the device created to measure the time-course of radioactivity in the whole blood with high temporal resolution. The data acquisition is performed with the dedicated PMOD module PSAMPLE. The PMOD software with its modular structure allows for comprehensive off-line analysis of radio tracer data.

The main application of the Sampler is the quantification of PET studies.

Quantification is unique and the gold standard methods require the arterial input function (AIF). The joint use of the twilite system and PSAMPLE software allows the accurate measurement and correction of the whole blood tracer activity. The corrected blood activity measurements are used to identify the plasma activity. This represents the essential information needed for quantification purposes. The PKIN module is the dedicated tool for blood data post processing and quantification. The present PKIN modeling tool offers an easy and intuitive access to the wealth of developed methods to a broader community.
