The blood analysis function is the main function of the blood lab computer, and allows the user to analyze sample sets. The functions related to PET studies are selected by choosing Blood Analysis from the main menu, and then Related to PET from the submenu. In order to use these functions, you should have first prepared a sample set by preweighing it (see the previous section).
Once you have selected blood analysis related to PET, you will be prompted to enter a password. This password is the same password used by PCAM on the VAX. After the password has been entered, the programme will attempt to synchronize clocks with CELIA. If the password was incorrect or an error occurs an error message will appear. Unfortunately, it is impossible to tell the difference between a network error and an incorrect password. Therefore the programme gives you a second chance to enter the password if an error occurs (please see the error descriptions in the Error Messages section of this document).
Once the clocks are synchronized, the programme will acquire the most recent run number from BRUTUS. You will then be presented with an entry screen that has the most recent run number already entered. If it correct, click on OK. If not, correct it using the <BACKSPACE>, <DELETE>, and number keys, and then click on OK. All data for a run is referenced on the computer using the run number. Therefore it is extremely important that the run number you enter is the run number of the study you wish to work on.
The programme will search the hard disk and then the VAX for patient data and sample time data. If this data does not exist, the programme will continue, and attempt to retrieve it at the end of the study.
Once all of this data has been checked for, you will be presented with a menu. Select either Scale or Well Counter from this menu, depending on which instrument you wish to use. The appropriate screen will appear.
