5 the start of the next RFA1 ON sequence should be set to sample the narrowest RF data pulse at least 10 times. Otherwise, significant edge jitter will be added to the detected data pulse. ASH Transceiver Block Diagram Figure 2 is the general block diagram of the ASH transceiver. Please refer to Figure 2 for the following discussions. Antenna Port The only external RF components needed for the transceiver are the antenna and its matching components. Antennas presenting an impedance in the range of 35 to 72 ohms resistive can be satisfacto - rily matched to the RFIO pin with a series matching coil and a shunt matching/ESD protection coil. Other antenna impedances can be matched using two or three components. For some impedances, two inductors and capacitor will be required. A DC path from RFIO to ground is required for ESD protection. Receiver Chain The output of the SAW filter drives amplifier RFA1. This amplifier in - cludes provisions for detecting the onset of saturation (AGC Set), and for switching between 35 dB of gain and 5 dB of gain (Gain Se - lect). AGC Set is an input to the AGC Control function, and Gain Se - lect is the AGC Control function output. ON/OFF control to RFA1 (and RFA2) is generated by the Pulse Generator & RF Amp Bias function. The output of RFA1 drives the SAW delay line, which has a nominal delay of 0.5 μs. The second amplifier, RFA2, provides 51 dB of gain below satura - tion. The output of RFA2 drives a full-wave detector with 19 dB of threshold gain. The onset of saturation in each section of RFA2 is detected and summed to provide a logarithmic response. This is added to the output of the full-wave detector to produce an overall detector response that is square law for low signal levels, and tran - sitions into a log response for high signal levels. This combination provides excellent threshold sensitivity and more than 70 dB of detector dynamic range. In combination with the 30 dB of AGC range in RFA1, more than 100 dB of receiver dynamic range is achieved. The detector output drives a gyrator filter. The filter provides a three-pole, 0.05 degree equiripple low-pass response with excellent group delay flatness and minimal pulse ringing. The 3 dB bandwidth of the filter can be set from 4.5 kHz to 1.8 MHz with an external re- sistor. The filter is followed by a base-band amplifier which boosts the de- tected signal to the BBOUT pin. When the receiver RF amplifiers are operating at a 50%-50% duty cycle, the BBOUT signal changes about 10 mV/dB, with a peak-to-peak signal level of up to 685 mV. For lower duty cycles, the mV/dB slope and peak-to-peak signal level are proportionately less. The detected signal is riding on a 1.1 Vdc level that varies somewhat with supply voltage, tempera - ture, etc. BBOUT is coupled to the CMPIN pin or to an external data recovery process (DSP, etc.) by a series capacitor. The correct value of the series capacitor depends on data rate, data run length, and other factors as discussed in theASH Transceiver Designer’s Guide. When an external data recovery process is used with AGC, BBOUT must be coupled to the external data recovery process and CMPIN by separate series coupling capacitors. The AGC reset function is driven by the signal applied to CMPIN. When the transceiver is placed in power-down (sleep) or in a trans - mit mode, the output impedance of BBOUT becomes very high. This feature helps preserve the charge on the coupling capacitor to mini - mize data slicer stabilization time when the transceiver switches back to the receive mode. Data Slicers The CMPIN pin drives two data slicers, which convert the analog signal from BBOUT back into a digital stream. The best data slicer choice depends on the system operating parameters. Data slicer DS1 is a capacitively-coupled comparator with provisions for an ad - justable threshold.

The TR1000 employs RFM’s amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of character- istics. All critical RF functions are contained in the hybrid, simplifying and speeding design-in. The receiver section of the TR1000 is sensitive and stable. A wide dynamic range log detector, in combination with digital AGC and a compound data slicer, provide robust performance in the presence of on-channel interference or noise. Two stages of SAW filtering provide excellent re - ceiver out-of-band rejection. The transmitter includes provisions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter employs SAW filtering to suppress output harmonics, facilitating compliance with FCC 15.249 and similar regulations.

RF-IVD, MODEL 1136, INTERNAL PHOTOGRAPHS The assemblies shown in Figure 1-3 consist of four Printed Circuit Board (PCB) assemblies. The lower board is the electrometer board. When it is used as a Diode Pod, it converts the current from the radiation detection diodes to digital values for transmission back to the Base Station. When it is used as a Base Station, it receives data from a Diode Pod and relays it to an Operator Module or a Personal Computer via a cable. The upper two boards shown in Figure 1 are the battery module and the RF transceiver. The fourth board is the antenna mounting pad (Not visible) located directly beneath the antenna. The first three boards slide into grooves in the extruded aluminum case. Figure 1 shows them as they are being removed from the case after the end panel has been removed. Figure 2 shows the assembly after the Battery module has been removed. Figure 3 shows the electrometer board after the RF transceiver has been unplugged. The blue cable connects the transceiver to the antenna.

OPERATIONAL DESCRIPTION Radio Frequency – In-Vivo Dosimeter "RF-IVD2" Model 1136 DESIGNED AND MANUFACTURED BY SUN NUCLEAR CORPORATION MELBOURNE, FL USA 321-259-6862 http://www.sunnuclear.com 1.0 Product Operational Overview The Sun Nuclear Model 1136 RF-IVD2 is a system that measures the radiation output of a radioactive substance such as a Co-60 source or a linear accelerator, during the treatment of a patient. Because the radioactive source is located near the middle of the treatment room an RF link makes the movement of personnel, patients and equipment around it safer, i.e. no cables to trip over and no cables to roll carts over. The system consists of 3 components: Display Module (user interface), Base Station (rf transmitter and receiver), and Detector Pod (rf transmitter and receiver). The Base Station and Detector Pod are identical and are interchangeable through system setup. The diode radiation detectors are connected to the Detector Pod through Lemo coaxial connectors. The radiation therapist connects the radiation detectors (diodes) to the Detector Pod and then positions them on the patient in order to measure the radiation from the accelerator. At this time, the patient is on the treatment couch of the accelerator, already positioned for treatment. The detector pod is battery operated and is positioned within 3 to 10 feet of the beam entrance to the patient. Also at this time, the beam is not on and the RF-IVD2 is not making a dose measurement. The therapist then leaves the treatment room that is shielded with approximately 3 feet of concrete and a heavy interlocked door. The patient is restrained on the couch because the treatment plan requires position accuracy to within millimeters, therefore no movement is allowed. Dose measurement is then remotely started on the RF-IVD2 from the Display Module in the control room and the accelerator beam turned on. A treatment fraction generally lasts for ½ minute or so. When the beam turns off, the RF-IVD2 is stopped and the dose value is displayed. The RF-IVD2 display value is recorded or printed on an accessory printer. The therapist then enters the room and removes the detector from the patient. The recorded RF-IVD2 measurement is a QA test that verifies the dose output during treatment from the radiation machine. The actual treatment plan is calculated in the Treatment Planning Computer (TPC – not part of the RF-IVD2) which uses dosimetry data acquired from a NIST traceable calibrated ion chamber and 3D water phantom. The plan output should also include the "expected" dose at the point of the IVD detector placement. Then the measured IVD dose and the expected TPC dose can be compared for verification. If the expected dose is not verified, the measured dose should not be used to adjust future treatments. Instead, an investigation should be conducted as to why the error occurred. The IVD is calibrated at the institution using the NIST traceable calibrated ion chamber as a standard, the same standard that is used to calibrate the accelerator and the TPC. Therefore, the IVD offers a closed loop QA test of the implementation of the plan. 2.0 RF Transceiver The RF Transceiver is a completely self-contained hybrid in a 7mm X 10mm, surface-mount, 20-terminal metal can. It operates at 916.5 MHz, +/- 0.2 MHz. The modulation is On/Off Keyed. We are using a baud rate of 4630 bits/sec. The data stream is Manchestered encoded. The manufacturer’s specification for the hybrid that we are using is attached to the back of this document. This hybrid is mounted on a two-sided circuit board with a bottom ground plane and a top copper poured ground plane around all of the circuit traces and component mounting pads. There is an 8-pin connector that connects the transceiver to the microcontroller based electrometer board beneath the transceiver’s printed circuit board . The transceiver gets its power, control and data thru the connector from the electrometer board. The transceiver’s power supply Voltage is 3.0V. The power is filtered to keep noise from the electrometer board from getting on the RF output. The two control lines place the transceiver in either transmit mode, receive mode or “Off” mode. There is one transmit line for data to the transceiver and one receive line for data from the transceiver. The RF output track on the printed circuit board from the transceiver hybrid is impedance matched to a 50 Ohm coaxial cable connector. The other end of the coaxial cable is plugged into another 50 Ohm connector that is soldered to the antenna mounting pad. The antenna mounting pad has a “Reverse SMA” connector that is not readily available to the consumer. The ¼ wave helical whip antenna mounts to the “Reverse SMA” connector. The case is an aluminum extrusion with metal end panels. The system has been tested to meet section 15.249 of Part 15. We are not measuring a patient biometric, i.e. a physical parameter of a human being. There is no electrical connection to the patient. We are measuring radiation coming from a radioactive isotope or a particle accelerator. A patient does not have to be present for this equipment to be used. 3.0 Location of Intended Use The radio frequency communication is only performed in the treatment vault of a hospital, clinic or university. The treatment vault is a shielded room having solid high density steel reinforced concrete walls and ceiling, a minimum of 3 feet thick. The door is an 8 inch thick steel and boron polycarbonate laminate. The treatment vault must be well shielded to protect personnel from very high energy x-rays (20 MV) and is built on the ground floor of the institution. The shielding to prevent high-energy x-rays from leaving the room also prevents RF energy from entering or leaving the room. Refer to the following System Block Diagram. 1 ® TR1000 916.50 MHz Hybrid Transceiver The TR1000 hybrid transceiver is ideal for short-range wireless data applications where robust operation, small size, low power co…
