  Piranha, even on this extremely low level, still makes corrections for the beam filtration. The Piranha can measure both kV and dose rate at very low levels for instance on Mini C-arm systems. Piranha can (as an example) successfully measure the tube voltage as low as 43 kV with a 25 µA tube current.

• Page 112: Hvl, Total Filtration, And Quick-Hvl

  Total Filtration and Quick-HVL The total filtration is measured continuously when the Piranha is used under fluoroscopy. The following pictures illustrates this excellent feature for the Piranha and the Internal detector (shown for Barracuda MPD): The fluoro is started and the total filtration is estimated and automatically displayed during two seconds.

• Page 113
  Fluoroscopy and Pulsed Fluoroscopy The displays with measured values are continuously updated every four seconds. Add 10 mm of aluminum. The Piranha will «notice» that the filtration is changed and shows a new total filtration value. The dose rate is now much lower. The added filtration does not affect measured kVp at all.

• Page 114: Pulsed Fluoroscopy

  Select type of measurement in similar way as for normal continuously fluoroscopy to setup the system. Piranha is set-up for this application to calculate the number of pulses per second (Hz or pps), the dose/pulse, and pulse dose rate. The picture below explain the difference between the pulse dose rate and the traditional dose rate.

• Page 115
  5. Measurements with the Piranha System Fluoroscopy and Pulsed Fluoroscopy The following pictures illustrates how the Piranha system is used this type of measurement. These pictures describes the check of the output levels in pulse fluoroscopy mode (showing Barracuda MPD).
• Page 116
  5. Measurements with the Piranha System Fluoroscopy and Pulsed Fluoroscopy using the Piranha Dose Probe. Hints: Pulsed fluoro screen is very handy to use for several applications and is not restricted to only measure pulsed fluoro. It has application when measuring in Cine mode with heavy filtered beam that make the signal too low to use the Cine mode or when the dose rate is extremely low.

• Page 117: Mammography

  Position Check. The mammography kV calibrations available for the Piranha is ranging from 18 to 49 kV. To confirm which range is used the digit 1 or 2 is displayed in square brackets on the bottom left corner of the QABrowser screen, as shown below.

• Page 118: Setting Up The Piranha For Mammography

  Piranha is repositioned. The kV and radiation waveform is always stored together with the RTD values and can be displayed by tapping the Wave button. The kVp calibration for Piranha is made without the compression paddle in place.

• Page 119: Kvp, Time, And Dose Measurements With The Internal Detector

  2. Make sure that the image receptor is positioned at a clinically relevant distance (typically 600 mm). 3. You should place the Piranha flat on the image receptor with its long axis parallel to the chest wall making sure the centre of the detector surface is placed in the centre of the light field, as shown in the pictures above (40 mm distance shown).

• Page 120
  3. Make a Position Check, as shown above. It is recommended to make the check at 28 kV. After the check the Piranha automatically changes back to the previously selected kV range. 4. Set kVp and mAs (or mA/time) to the desired values.

• Page 121: Dose Measurements With The Piranha Dose Probe

  5. Measurements with the Piranha System Mammography 5. Make an exposure. The RTI logo flashes to indicate that the Piranha has detected the exposure. 6. Read the values in the RTD. 7. Repeat measurement for other generator set values. There are some mammographic units that are bit peculiar when it comes to kV measurements, for instance The Hologic Selenia and IMS Giotto.

• Page 122: Hvl Application

  8. Repeat the measurement for other generator settings. To get a good HVL value, using the Piranha Dose Probe, you must correct it according to the tables in the Piranha Dose Probe DETECTOR DATA manual. It is often more convenient to measure HVL with the Piranha using the built-in HVL application.

• Page 123: Quick-Hvl

  Quick-HVL Quick-HVL The Piranha is able to measure HVL for mammography in one shot. Quick-HVL is available for measurements with or without compression paddle. If the parameter «All w. HVL» is chosen, the QABrowser will display quick-HVL values for every measurement.

• Page 124: Corrections For The Compression Paddle

  5.5.7.1 Corrections for the Compression Paddle The Piranha is well collimated above its small detector area, and will measure the same whether the compression paddle is placed directly on top of the Piranha or high above. This is NOT true for an ion chamber.

• Page 125
  (at 605 mm SDD). A practical consequence of usage of the normalizing function and scatter factor is that the Piranha can be kept at the same position on the breast support all the time when data is collected for AGD.

• Page 126: Beam Correction Factor

  Piranha is placed flat on the breast support. (This assuming that the focal point is situated at the chest wall, which normally is the case.) You can find the product version on the label on the back side of your Piranha. Distance from…

• Page 127: Average Glandular Dose, Agd (Mgd)

  On the other hand, the HVL measurement should be done without any scatter contribution and with good geometry. The Piranha is well collimated above its small detector area. Due to this fact it registers a narrower angle of the X-ray field and thus much less scattered radiation compared to an ion chamber.

• Page 128: Mammographic Pre-Pulses

  1 s and the waveform recording time to a corresponding time. It is important to cover both signals. In this measurement setup, the Piranha will add the dose from both pulses. This is OK if the radiation quality is not changed between the signals.

• Page 129: Dental And Panoramic Dental

  This topic will describe how to measure kVp, dose, and time for a Dental and Panoramic Dental X-ray units using the Piranha only. Set up the Piranha and the handheld computer according to the description in Setting Up the Piranha .

• Page 130
  The challenges instead arise for the mechanical setup needed to position the detector in right position. The small and narrow field is only a few millimetres. The Piranha detector has very narrow detector area and is very thin and a special holder (optional) can be used to position the Piranha without any problem.
• Page 131
  The Piranha has addressed these challenges. Since the panoramic scan has an exposure time of about 10 to 20 seconds, the Piranha is set up to continuously update the display during the scan. It is preferable to select a single parameter display and angle the Palm holder, making it easy to read the values during the scan, from a distance.

• Page 132: Kvp, Time, Dose, And Dose Rate

  Use the same procedure as for the normal radiography measurement but select Dental instead of radiography and select Tube voltage as parameter. A 200 ms delay is default. 1. Set up the Piranha and the handheld computer according to the description in Setting Up the Piranha .

• Page 133
  3. It is recommended to make a check measurement to confirm that the detector area is uniformed radiated. Select a exposure time of at least 400 ms. The Piranha automatically changes back to the previous selected kV-filter after the check exposure.

• Page 134: Waveforms

  5. Measurements with the Piranha System Dental and Panoramic Dental The Piranha now first analyses the beam and displays the type of waveform. This is done once. Then the estimated total filtration is displayed. Read the measured values from the display.

• Page 135: Panoramic Systems

  Use the same procedure as for the normal dental measurement but select Panoramic Dental instead of radiographic and select Tube Voltage as parameter. A 200 ms delay is default. 1. Set up the Piranha and the handheld computer according to the description in Setting Up the Piranha .

• Page 136
  When the system passes the test, you can trust the kV reading. 7. The Piranha changes automatically back to the previous selected kV range after the Position Check. As default this is range 55 — 105 kV, R2[4] as indicated on the QABrowser screen.

• Page 137: Hvl, Total Filtration, And Quick-Hvl

  9. Select kV, mA, and scan time. 10. Start the scan. A little triangle in the RTD indicates that the Piranha detects the radiation. It is not needed to use the whole scan for the purpose of measure the kV since the display is continuously updated.

• Page 138: Ct Kvp

  Another problem is to «find» the beam, especially when using a small slice width. All these problems are minimized when using the Piranha since it can «move with the table» through the beam while the tube is in the top position. This is can easily be obtained by measuring while a topogram (scout/pilot image) is taken.

• Page 139
  5. Measurements with the Piranha System 3. Start the QABrowser and select CT from the Select type of measurement menu. 4. Select Tube voltage. 5. The real-time display for tube voltage is now shown. At the bottom of the screen you can select kV range and calibration.

• Page 140: Parameters For Ct Scanner Models

  If the Piranha is positioned in a correct way, the position is accepted and the real-time display is shown again. If not check the position of the Piranha and/or increase the slice width if possible.

• Page 141: Quick-Hvl And Total Filtration

  5. Measurements with the Piranha System With the calibration C1 the total filtration can be measured and the Piranha automatically corrects the kV value accordingly. It is optional to set a known total filtration instead, see the table below. To achieve optimal measurements of the total filtration, first perform a measurement at a low kV, preferable 80-100 kV.

• Page 142: Mas-1, Invasive Mas Probe

  This means that the measurement starts when the mAs-probe detects the tube current. The measurement is performed in the same way if you use a multi- parameter display. In that case the default trig is the Piranha and what is said below about false triggering can be ignored.

• Page 143
  1. Connect the MAS-1 probe to the X-ray generator as described in the MAS-1 User’s Manual. 2. Connect the MAS-1 probe to the external probe input. 3. Set up the Piranha and the handheld computer according to the description in Setting Up the Piranha 4.
• Page 144
  The MAS-1 probe can also be used for measurement of tube current during fluoroscopy. To measure fluoroscopy tube current with the Piranha MAS-1 Probe 1. Setup the Piranha according to the description earlier in this manual. 2. Connect the MAS-1 probe to the X-ray generator as described in the MAS-1 User’s Manual.

• Page 145: Mas-2, Non-Invasive Mas Probe

  Tube Current Probes 5.8.2 MAS-2, Non-invasive mAs Probe This section describes how to measure mAs, using the Piranha in the x-ray beam to trigger the measurement. This means that the measurement starts when the Piranha detects the radiation. The MAS-2 probe uses a current clamp probe to measure mAs and mA non-invasively.

• Page 146
  5. Measurements with the Piranha System Tube Current Probes 7. The figure to the left shows the result from an exposure with 80 kV, 100 ms, and 25 mA. The exposure time is measured with the MAS-2 probe. If you would get a message as shown in the figure to the left, the mAs probe is probably connected in the wrong direction.
