OPERATOR'S MANUAL FOR THE
SYSTEM
2 SYSTEM DESCRIPTION 2.1
GENERAL The System is compact and easily transportable within a typical Radiotherapy or Radiology treatment clinic or other laboratory. The dosimeters are placed on the patient and measured by the Reader before and after irradiation. All data is output via the mobileMOSFET Remote Monitoring Dose Verification Software, provided with the system to control the Reader and generate a report for the patient’s record. In operation, the mobileMOSFET Reader is set up in the treatment room and connected to the required number of Dosimeters. The maximum number of MOSFET dosimeters is five per Reader. Alternatively, one can connect a single MOSFET Linear Array to a mobileMOSFET Reader. The mobileMOSFET Software can support up to eight Readers simultaneously during a single procedure. The measurement procedure is controlled by a PC using the mobileMOSFET Software through the RS-232C cable or Best Medical Canada Ltd provided wireless transceiver (BMC Part No. TN-RD-38). MOSFET dosimeters or the MOSFET Linear Array can be taped to the patient or placed in a phantom. The dose measurements are carried out by clicking the “START” and “READ” buttons on the Dose Measurement Screen. In applications, the mobileMOSFET Software can: • Handle up to five (5) verification sessions simultaneously. Operations in each session are totally independent. • For each verification session, up to eight (8) Reader modules (or up to 40 dosimeters/8 Linear Arrays) can be used. Operations on each Reader module (i.e. Start or Read) can be performed collectively or individually. • For each Reader module, all dosimeters will be measured at the same time, however, measurement on individual dosimeters can also be easily performed (see Section 4.6). The following section contains a detailed description of the System components. For setting up, operating and calibrating the System, see Sections 3.0, 4.0 and 7.0, respectively.

OPERATOR'S MANUAL FOR THE 3.2
SYSTEM
BATTERY OPERATION The mobileMOSFET is intended to operate on battery power. The battery level for the mobileMOSFET Reader Module is indicated on the Equipment Setup and Dose Measurement screens, as well as windows that will pop-up advising you if your battery level is getting low. There are two methods to recharge the batteries, Fast Charge and Trickle Charge. The charging status is visible by the LEDs on the side of the Reader. A green LED indicates that the unit is in Trickle Charge, while a red LED indicates the Reader is in a Fast Charge. To Fast Charge the mobileMOSFET Reader Module, ensure the unit is turned OFF prior to connecting the unit to a power source. A Fast Charge will completely charge a mobileMOSFET with a drained battery in approximately three hours. Once the batteries are charged, the red LED will go out and the green LED will come on, indicating Trickle Charge. Trickle Charge supplies the battery with power at a continuous low rate thereby keeping it charged. Trickle Charge allows the user to continue treatment sessions when the Reader's battery is running low. Instead of having to be concerned with the battery losing power, the user can just continue on with the session. To use Trickle Charge, the mobileMOSFET must be ON and the power supply connected to the Reader. Prior to first use, place the Reader on Fast Charge (mobileMOSFET turned OFF and power connected) until the red (Fast Charge) LED goes OFF and the green (Trickle Charge) LED comes on. This will take a maximum of three hours.
Figure 3-1: mobileMOSFET Reader Module Status Panel 3.3
CONFIGURE BIAS SENSITIVITY The Bias located inside the Reader provides regulated voltage to the MOSFET dosimeters. This ensures reproducibility and linearity over the lifetime of the MOSFET. The mobileMOSFET Reader provides a choice of two Bias sensitivities in order to cover a wide range of doses with optimum reproducibility. The system allows you to choose between two options: Standard (STD) for routine use, or High (HI) Sensitivity for low doses. ATTENTION BEFORE USING THE mobileMOSFET, IT IS RECOMMENDED THAT YOU CHOOSE ONE SENSITIVITY SETTING AND LEAVE IT THERE FOR THE DURATION OF THE LIFE OF THE DOSIMETERS TO BE USED.
Page 18 of 62
OPERATOR'S MANUAL FOR THE
SYSTEM
To determine which sensitivity best meets your needs, please review the chart in Section 5.3, or contact Best Medical Canada Ltd for a copy of our Technical Note #3, “Reproducibility Using Model TN-RD-22 Dual Sensitivity Bias Supply”. A Sensitivity Switch is located on the front of the Reader adjacent to the five dosimeter ports on the left-hand side (refer to Figure 5-4: System Connections). The switch is recessed so that it cannot be accidentally switched to the wrong setting. In order to change the setting, use a fine tipped object, e.g. a pen, to move the switch to the appropriate setting. 3.4
CONNECT DOSIMETERS MOSFET dosimeters require a permanent connection to a Reader for optimal accuracy readings. If your dosimeters are to be used for the first time, connect them to the Reader for at least one to twenty-four hours before use. Only connect and calibrate those dosimeters that are to be used (up to five (5) individual MOSFETs or one (1) Linear Array), and follow this procedure when ordering replacement dosimeters. You must designate the type of dosimeter, single or array that you are using, i.e. TN-252LA5, when configuring the equipment. (For Calibration, see Section 7) NOTE:
Single MOSFETs and the MOSFET Linear Array CANNOT be read simultaneously on a Reader. If you wish to read the MOSFET Linear Array, ensure that no MOSFETs are connected to the Reader and then designate which type of Linear Array you will be using. To do this, go to the Equipment Setup window in the mobileMOSFET Software, click on the Configuration button and follow the instructions provided. Conversely, if you wish to read single MOSFETs, ensure the MOSFET Linear Array is not connected to the Reader.

SYSTEM
CONNECT SYSTEM 1) Connect the system together with all cables (see Figure 3-3: Equipment Set-up for a Wireless Connection, below). NOTE: If you are using the wireless connection, DO NOT connect the READER-PC CABLE. 2) Prior to first use, place the Reader on Fast Charge. Turn the mobileMOSFET OFF and connect the universal power adapter for the Reader to the “POWER IN” jack on the back of the Reader, then plug the country specific line cord into the AC outlet. The red Fast Charge LED will go on. When the Fast Charge LED goes off and the green Trickle Charge LED goes on, the battery is fully charged. This will take a maximum of three hours. 3) Power on the system and allow the electronics to warm up for at least fifteen (15) minutes before proceeding. If the green Power LED is not flashing, the power switch must be switched up to the momentary position to reconnect the battery power.
3.6
CONNECT PC
3.6.1 Wireless Connection Mount the TN-configured Bluetooth™ wireless transceiver on an interior wall of the treatment room. Attach the 5V DC power supply, and connect the transceiver to the PC’s COM port using the RS-232 cable (See Figure 3-3: Equipment Set-up for a Wireless Connection).
