Advanced functionalityEverything you want to doThe BV Pulsera consists of a mobile C-arm standand a Mobile View Station. It offers a choice of Xray and imaging functionality, as well as a variety ofoptions and accessories. The functionality of thecomplete system is described in the following pagesand the text that is important for you depends onthe system configuration chosen.Mobile C-arm stand Ultra compact foot including pushbar andhandles for easy maneuverability and positioningof the stand. Compact, counterbalanced C-arm provides allrequired projections. Extended rotation: C-arm rotates a full 135º C-arm has a very low lateral position. Rear wheel steering concept for easymaneuverability and positioning of the stand Dedicated parallel movement with ergonomicallydesigned handgrips for easy positioning alongsideoperating table. Source to Image Distance (SID) is 100 cm. Streamlined user interface for easy control duringprocedures. Cable deflectors brush aside any floor cables. System includes footswitch, handswitch,radiation indicator.The ultra compact footensures easy maneuverabilityand positioning of stand.6 Remote control Laser alignment tool Ergonomically designed C-arc handles guaranteeeasy C-arc positioning.X-ray generation Rotating anode X-ray tube with excellent coolingrate for the most demanding interventionalprocedures. Pulsed Acquisition Mode Pulsed Fluoroscopy Mode Because of the integrated pre-filter, the compactconverter X-ray generator ensures a homogeneousX-ray spectrum with the lowest possible skinradiation. BodySmart will find the region of interest, definethe optimal measuring field and follow the regionof interest, ensuring optimal kV/mA settings andresulting in the best possible image quality. Anatomically Programmed Fluoroscopy (APF)sets fluoroscopy parameters automatically,providing consistent image quality for everyexamination type. Automatic High Penetration for optimal imagequality in heavy objects even in the steepestprojections e.g., lateral hip.C-arm steering with parallel movement for positioning alongsideoperating table
X-ray collimation Full lead shutters can be rotated and movedtogether or independently to provide realprotection against direct radiation and thusreduce scatter radiation. An additional beam filter (of 0.1 mm Cu) reducespatient and clinical staff skin dose by 40% overconventional filters. Shutters and Iris can be set on Last Image Hold. The Iris collimator limits the X-ray beam to theactual field of the image intensifier Automatic Shutter Positioning for functionalitythat will position the shutters according to theregion of interest with one touch of a buttonImaging System Choice of two triple-mode, image intensifierconfigurations:- 23/17/14 cm (9/7/5").- 31/23/17 cm (12/9/7"). Compact CCD/TV camera Image rotation digital, live and on Last ImageHold Carbon fiber X-ray grid. Digital rotation and mirroring up/down andleft/right 1 K2 imaging throughout whole imaging chainX-ray modes Low Dose Fluoroscopy with Last Image Hold. High Definition Fluoroscopy with Last ImageHold. Real pulsed fluoroscopy (12.5 pulses/second)providing low dose motion blur-free fluoroscopicimages. Half- and quarter dose pulsed fluoro modesreduce dose up to 75%. SharpShot digital exposure mode for diagnosticquality images and archiving purposes ld. Radiographic mode for cassette exposures. Image grabImage processingSmartVision, a highly advanced, full digital 1Kx1Kimaging chain in combination with unique state-ofthe art image processing functions ( likeBodySmart, Automatic Shutter Positioning,advanced noise reduction algorithms) includes: Dedicated 12-bit image pipeline processor.

Trace-subtract shows maximum opacification ofvasculature using CO2 or iodine contrast. ViewTrace creating a trace image, post processed Roadmap images support catheter guidance. SmartMask reduces dose and contrast mediumusage by re-using previously acquired maskimages for roadmapping Remask lets you reselect the best image in yourrun as a mask image for contrast runs. Landmarking highlights background anatomy forreference. Real-time pixel shift compensates for movementartifacts. Subtraction on/off simplifies the orientation forsubtracted images or during roadmap procedures.(Remote control, MVS)Choose either a 9"or 12" triple-mode image intensifier,to match your applicational requirementsVascular imageThe Vascular Package, which includes subtraction,can easily be combined with Extended Processingfunctions such as Zoom and MeasureThe Vascular Package, which includes subtraction,can easily be combined with Extended Processingfunctions such as Zoom and Measure8
Mobile View Station with uniqueintelligent viewing conceptThe ultra compact Mobile View Station perfectly fitsin the surgical workflow. The unique intelligentviewing concept of the Mobile View Station providesyou with easy transportation, easy system set-up,flexible monitor positions and extended viewingcapabilities. When the Mobile View Station is in theOR, patient demographics can easily be enteredmanually or retrieved via the hospital network. Afterentering these data, the monitors can be rotated andthe clean side of the MVS can be positioned as closeas possible to the operating table and operating staff.Depending on the way you work – standing orseated- excellent viewing is guaranteed by the heightadjustment possibilities of the monitors. After theprocedure is finished, you simply turn the monitors180 degrees and you can post-process the images andsend the to the PACS.Height of the LCD monitors can beincreased/decreased with 25 cm (10”). This steplessheight adjustment can be done manually and willbring ergonomical operation, easy transportationand easy storage Designed to accommodate paper/transparencyprinter, Medical DVD Recorder, ViewForumSurgical Workstation and a fully integratedDICOM connectivity solution. On top of the standard 500 images, the followingmemory extensions are available:- 5,000 images on hard disk (8 frames/second).- 10,000 images on hard disk (25 frames/second).System controlsA variety of intuitive system controls provide theutmost flexibility in controlling procedures.User Interface on C-arm Stand Streamlined user interface for easy control duringprocedures. Includes pre-set AnatomicallyProgrammed Fluoroscopy parameters (APF). Workflow oriented flat panel shows functionalseparation of keys and can be easily cleaned. Choice of language is incorporated into thesystem (English/French/Spanish/Swedish/German)Two different types of LCD monitors can beprovided: 18" standard color LCD monitors providingoptimal image quality 18" high brightness color LCD monitorsproviding superb image quality. Optionally a height adjustment for the monitorsis available.9
Advanced functionalityUser Interface on Mobile View Station Vequion competent user interface consisting ofon-screen display and alphanumeric keyboardwith touchpad. Touchscreen option for the left monitor. Easyaccess to the different menus, performing patientadministation or post-processing on acquiredimages, with a tip of your finger . Touchscreen iscompatible with the High Brightness andStandard color LCD monitors. Multi-patient database provides fast access toclinical images and patient data. Image handling can be controlled via remotecontrol, C-arm stand, or Mobile Viewing Station. Choice of language is incorporated into thesystem. (English/French/Spanish/Swedish/German) DICOM functionality can be operated at theMobile View Station.10Safer treatment environmentWith every new system Philips Medical Systemslook at how we can incorporate better shielding andimprove our X-ray exposure to further reduce dose.A number of Philips unique features help drasticallylower dose during procedures: Unique beam filters reduce patient skin dose by40% over conventional filters. Pulsed fluoro modes (1/2 dose and (1/4 dosemodes) reduce dose up to 75%. Independently movable lead shutters providebetter radiation protection than semi-transparentshutters. SmartMask saves dose and contrast medium byletting you re-use previously acquired subtractedand non-subtracted images as masks forroadmapping. The system lets you adjust the collimator,shutters, and image orientation during Last ImageHold without applying radiation. Automatic Shutter Positioning will position theshutters according to the region of interest, withone touch of a button.
Handheld Remote ControlThe remote control unit is a handheld infraredkeypad used to control the main image handlingfunctions. For sterile operation, it can be used in atransparent sterile plastic cover.

LabVIEW uses the parallel communication to send the joint angles of the robot arm to the ARM. ARM microcontroller uses five PWM (Pulse Width Modulation) signals in order to control the robot arm, which was geared up with servo motors. Robot arm was controlled manually through the LabVIEW GUI (Graphical User Interface) controls.
