Abstract
Provided is a data acquisition system comprising a CPU, radiation detector, buffer, and a storage device in communication with the buffer and which is capable of storing information received from the buffer. The data acquisition system includes a method for sequentially monitoring data from one region of interest based on data obtained from a previous region of interest, and finally recording the data of a final region of interest for use as medical data.

A method of acquiring medical data using a data acquisition system including a radiation detector, a storage device, and a processor, said method comprising the steps of:
- administering a particular bolus to a patient;
- acquiring, using said radiation detector under control of said processor, a first set of data from a monitored region that is a first region of interest;
- for n=2 to N, performing, based on the transition of the particular bolus through the patient, the steps of:
- a) detecting, utilizing the bolus and using said radiation detector under control of said processor, an (n−1)th trigger condition based on an (n−1)th set of data,
- b) defining, using said processor, an nth region of interest different from the (n−1)th region of interest in response to said (n−1)th trigger condition;
- c) acquiring, using said radiation detector under control of said processor, an nth set of data from the nth region of interest;
- and
- d) repeating steps (a) through (c) for each value of n, where N is equal to or greater than 3;
- and then
- recording said Nth set of data into said storage device for including in said medical data.
