1 RT Workspace from Standard Imaging

2 In 1895 Wilhelm Röntgen discovers the X-ray (receives Nobel prize in 1901) From radium was chiefly used for radiation treatment (based on work of Marie Curie who received 2 nobel prizes for her work)

3 The Cobalt Bomb developed in the early 1950 s The first machine capable of irradiating tissues deep inside the body Aim and shoot

4 From 1950 to 1970 the linear accelerator was developed and improved In 1971 the CT was introduced and 3D planning became a possibility No longer point and shoot

5 MRI introduced in the 1970s PET introduced in the 1980s MLCs and IMRT introduced in the 1990s IGRT introduced in the 2000s With more complicated machines and treatment techniques comes more complicated planning

6 Physician Consult (Physician) Plan Second Check (Physicist) Weekly Chart Audit (Therapist) Desk Notification (Front Desk) Treatment Scheduling (Tx Scheduler) Simulation (Physician, Therapist) Treatment Planning Treatment Planning (Physician, Dosimetrist, Physicist) Dosimetrist, Physicist) Daily Patient Specific QA (Physicist) Treatment Delivery (Therapist) Review of Images (Physician) Weekly Weekly Chart Check (Physicist) Weekly Management Visit (Physician) Completion of Treatment (Front Desk, Tx Scheduler)

7 Patient Volume Imaging (Imaging Tech) Images/Patient set up in TPS (Dosimetrist) Treatment volumes Contoured and Rx (Physician) Plan Creation (Dosimetrist) Plan Review (Physician, Physicist) Move plan to R&V (Dosimetrist) Order Beam Modifiers (Dosimetrist) Prepare plan for IGRT (Dosimetrist) Prepare plan for QA (IMRT) (Dosimetrist) Print the plan (Dosimetrist) Billing (Dosimetrist) Treatment preparation Plan QA (Physicist) Collect QA data (Physicist) Analyze QA data (Physicist) Prepare QA reports (Physicist) Billing (Physicist) Plan QA

8 Satellite Clinic A 25 Km West Main Hospital Satellite Clinic B 25 Km East

9 Developed in a group of clinics to solve a problem Wanted a solution that could be accessed from any computer Wanted a solution that would automatically notify each person when a process required their attention Wanted a solution that was intuitive so that any user could be up and running in a minimal amount of time

10 SQL Server Database Full SQL Server recommended but SQL Server Express can be used (free) Can be network based or web based Client software can be installed on any computer that has access to the database

11 Filter and Sort A filter bar allows the user to filter the board on any column s information. Clicking a column header sorts the board based on that column s information The Workflow Boards All tasks necessary to complete a radiotherapy plan are tracked. Clicking on the board to complete a task automatically lets the next person in line know that they have a new task to complete Colleague s ToDo List View any other RT Workspace user s ToDo list perfect for covering during vacations, etc.. Personal ToDo List Items are added automatically from the boards or manually by any RT Workspace user in a single glance know exactly what tasks need your attention

12 Planner Physician

13

14 With improved communication every team member can function more efficiently Physicians know in a single glance what is required of them Dosimetrists spend more time on planning instead of searching out answers to questions Therapists don t have to worry about making sure their patients are ready to start treatment

15 A dosimetrist reduces their unproductive time 15% (1.2 hours per day recovered) That equates to $14,400 per year* in recovered productivity Three dosimetrists = $43,200 per year Multiple sites??? *salary.com May 2011 Average medical dosimetrist salary = $96,825/year

16 RT Workspace was invented by a physicist so there are several tools built into the software specifically for physics Detailed equipment manager includes tracking calibrations and notifying when calibrations are due TG142 Monthly Linac QA Module Patient specific IMRT QA Module Electron cutout output factor module

17 In a single glance know where every patient is in the planning process Increase efficiency and productivity throughout the clinic Happier team members and more satisfied patients

19 The TaskGroup 142 report : Quality assurance of medical accelerators specifically spells out QA for imaging systems used in radiotherapy Planar MV and kv imaging (Monthly) Scaling Spatial resolution Contrast Noise Uniformity

20 The TaskGroup 142 report : Quality assurance of medical accelerators specifically spells out QA for imaging systems used in radiotherapy Cone Beam CT (Monthly) Geometric Distortion Spatial resolution Contrast HU Constancy Noise Uniformity

21 Some Machine QA Tasks that are called for in TG 142 Light/radiation field congruence Collimator, gantry and couch rotation isocenter (starshot) Jaw Positioning Radiation vs mechanical isocenter MLC Tests

22 PIPSpro QC Software measures MV and kv imager performance allowing you to quantify the quality of your imaging systems and track the degradation over time. Powerful analysis engines allow for important machine parameter testing

23 Invented by one of the physicists that was on the team that invented the Las Vegas phantom included with most imagers Realized that a subjective test wasn t good enough and could result in acceptance even with poor image quality The QC-3 phantom and PIPSpro were invented to provide objective, quantifiable and repeatable results for image quality Las Vegas Phantom QC-3 Phantom and stand

24 Developed for on board kv imaging systems including Varian, Elekta and Cyberknife Custom stand for Cyberknife systems uses fiducial tracking tools on the Cyberknife system to automatically position for image acquisition

25 MV (EPID) and kv (OBI) Imager QC The QC-3 phantom (MV) and the QCkV-1 phantom (kv) provide quantitative results for resolution, contrast-to -noise and overall noise of the imaging system

26 There are over 55 publications that validate the use of PIPSpro software and published results exist for most MV imagers of what to expect when utilizing PIPSpro software and the QC-3 phantom. With these published results it is easy to verify whether your imager is performing to specification.

27 Cone-beam CT testing CBCT module automatically analyzes image sets of the CATPHAN phantom included with Varian and Elekta systems Comprehensive QA of the CBCT imaging system in less than a minute!

28 Powerful analysis engines allow PIPSpro to perform important TG142 machine parameter testing utilizing specialized phantoms and your machine s imaging system Radiation Field/Light Field alignment tests Jaw position testing Gantry, couch and collimator rotation analysis (starshots) Stereotactic isocenter alignment test (Lutz test) MLC testing

29 The TaskGroup 142 report : Quality assurance of medical accelerators specifically spells out QA for imaging systems used in radiotherapy Planar MV and kv imaging (Monthly) Scaling Spatial resolution Contrast Noise Uniformity (Coming Soon)

30 The TaskGroup 142 report : Quality assurance of medical accelerators specifically spells out QA for imaging systems used in radiotherapy Cone Beam CT (Monthly) Geometric Distortion Spatial resolution Contrast HU Constancy Noise Uniformity

31 Other TG142 tasks that are covered by the tools in PIPSpro Light/radiation field congruence Collimator, gantry and couch rotation isocenter (starshot) Radiation vs mechanical isocenter (stereo) Jaw Positioning MLC Tests

32 Quantitative, repeatable results for imager quality including kv and CBCT testing Complete most TG142 tasks for imager quality assurance quickly, easily and accurately Recommended in the TG58 report on Clinical use of electronic portal imaging Perform important TG142 machine QA Speed up QA by using imagers and powerful analysis engines in PIPSpro eliminating the need to use film.
