Introduction to Biograph - Part 3 - Images

Introduction to Biograph - Part 3 This concludes Part 3 of the Introduction to Biograph PET/CT web based training; syngo MI Acquisition Workplace.  You should now be able to:  Describe the user interface of the syngo MI Acquisition Workplace and state the purpose of the chronicle, task cards and subtask cards   List the steps of patient registration and selecting a study Demonstrate the steps for positioning a patient and acquiring the scan  Describe the functions of reconstruction and auto tasking   By the end of this course you will be able to:  Describe the user interface of the syngo MI Acquisition Workplace and state the purpose of the chronicle, task cards and subtask cards   List the steps of patient registration and selecting a study Demonstrate the steps for positioning a patient and acquiring the scan  Describe the functions of reconstruction and auto tasking syngo is used on most Siemens Imaging Workstations   Task Cards selectable on left (left monitor) or right (right monitor)   Divide imaging and display functions   Active task card is highlighted   Menu changes with corresponding task card selection Protocol Chronicle displays a list of activities that are performed by the protocol   The Active Activity is indented   The Activity Name is displayed on the card   Squares indicate reconstruction jobs for that activity Subtask Cards contain groups of parameters controlling different parts of the task including: scanning reconstruction automatic processing The Active Card will be highlighted as seen in the image below. The Status Bar is located at the bottom of the display.  It contains the following information: Left - Examination specific information Center - Warnings, messages, and application icons Right - storage capacity icons showing available disk space Storage Capacity Indicators turn red when the disk space is low. The PET System Alert will indicate the following issues: Problem with ICS/ACS/Gantry Communication Click the System Alert icon to view the PET Acquisition monitor Restarting the PET Computers (ACS and PRS)  Options >> Restart PET Computers  The PET Cine Display feature is located under the Options menu. It is a MIP generated image. Visual representation is not intended for diagnosis. Each frame represents and intensity projection from a different angle. (1) Selected reconstruction (2) Animated cine display (3) Pause button stops the playback and switches the display to the frame scrolling window (4) Click to change the rotation direction (5) Displays the current frame rate. Enter a new value to change the rate, or use the up/down buttons to advance the frame rate in single frame increments (6) Use the up/down buttons to advance the frame rate in single frame increments Select Patient >> Register to begin entering patient information. Enter the following information in the Patient Registration window: (The 5 fields within the red rectangle are DICOM required) a.  Last name b.  First name c.  ID d.  DOB e.  Sex f.  Weight g.  Hospital Name h.  Physician/Operator information i.  Select study (PETCT)   Select Patient >> Register. Within the Patient Registration window enter the patient’s last name. Click the Search button at the bottom of the window. Within the Patient Search window, click on the desired patient. Click OK.      Once the table is in position, the patient may require one or more positioning accessories. (7) Click the play button to start the playback and return to the cine playback window (8) Click to display the previous frame (9) Drag the scrollbar with the mouse to select individual frames for display (10) Click to display the next frame (11) Displays the width (W) and center (C) of the window. The width value is the range of grayscale values displayed. The smaller the width the greater the contrast. The center value is the midpoint of the grayscale at the midpoint of the window range, and thus the brightness level of the image.    To access the Patient Model Dialog, enter the required patient data in the Patient Registration window. When complete, click the Exam button or select Patient then Exam from the menu bar.  On the Examination Card click the Select/Change Exam button. 1.  Choose Adult or Child Protocols. 2.  Mouse over the body image or icons to select the protocol. 3.  Select to replace or append protocol. 4.  If appending a protocol, select to cut or keep the topogram.   5.  Select if/how to show reference lines. 6.  Select patient position. 7.  Select API Language. 8.  Click OK to confirm entries.   Acquisition Modes Whole Body Dynamic Cardiac Gated Respiratory Gated Dual Gated Select each tab below view information on the Step and Shoot and Continuous Bed Motion (CBM) protocols. •  Bed moves sequentially in equal distances determined by the PET axial FOV •  Standard on all Biograph scanners •  Bed is moved continuously through the PET FOV •  Optional license needed Select the tabs below to view information about acquiring the CT scan. Verify the CT scan parameters on the Scan subtask card. Review the Auto Tasking subtask card if needed. Verify the CT reconstruction parameters on the Recon subtask card. First you will need to verify the routine CT parameters defined on the CT Routine subtask card. When all parameters are set, click the Load button. When the system prompts you to move the table into position, select the Move button on the Control Box. When prompted, press the Start button on the Control Box. Select the tabs below to view information about acquiring the PET scan. The first step for PET acquisitions is to complete the radiopharmaceutical (Pharm field), dose (Dose and mCi fields), scan length, and table position on the Routine subtask card. On the Routine subtask card click the Residual Dose icon to enter or edit the residual dose. On the Recon subtask card, edit the reconstruction parameters from the Recon method menu. Specify any automated tasks on the Auto Tasking subtask card. Click the Load button to activate the PET scan. Press and hold the Move button on the Control Box. Click the Start button on the Control Box. PET Acquisition Monitor (PAM) 1. Remove jewelry, glasses, prosthetics, etc. 2. Position patient on the table using necessary accessories 3. Position arms up for lung, thorax and abdomen scans. This will: a. Reduce beam hardening and scatter artifacts b. Reduce CT FOV truncation artifacts c. Improve PET IQ 4. Ensure object of interest is as near to the center of the measuring field as possible a. Avoid image artifacts on subsequent reconstructions 5. Make sure patient is comfortable and immobilized. a. Avoid motion artifacts b. Avoid poor attenuation correction 6. Make sure IVs and patient leads are long enough and can’t get caught anywhere.   1. Move the table vertically to the appropriate height. 2. Move your patient horizontally into the gantry. 3. Laser markers emanate from 3 points in the gantry opening. 4. To turn on the laser markers, use the button on the gantry. 5. Center the patient in the FOV. 6. Patient must remain still and you should observe the patient.   Select the tabs below to view the fields available for reconstructing a CT image. Select the tabs below to view the fields available for reconstructing a PET image. Secondary Monitor (left) Primary Monitor (right) Viewing Examination TrueD Basic Recon 3D (optional Fused Vision) 3D (optional Fused Vision) Life (online CT user documentation, LifeNet)   Ensure the laser is positioned at the start of the imaging region.   Check topogram parameters for accuracy on the Routine subtask card.   Adjust parameters on the Scan subtask card.   Auto Tasking automatically sends the acquired image to viewing, filming or transfer.   5. 6. 7.    The final steps will require you to first click the Load button. Next, click in the Topogram pink box to start the prompt. Press the Start button on the Control Box. Step & Shoot CBM
