Operational strategy

Measurement

dlc quest crack download It is important that the length of the prostate is known and that the robot is positioned at the bladder neck. The measurement phase of operation allows the surgeon to move the robot under computer control along the prostate from the bladder neck to a landmark feature - the Verumontanum - to define the region in which cutting will take place. Cuts past the verumontanum may damage the sphincter muscles so these are to be avoided. The surgeon estimates the position in the prostate using visual cues - i.e. his skill in identifying features from a video image from within the prostate. The image below shows the screen the surgeon sees while measuring the prostate. In the top left is a real time camera image from within the prostate. To the right is a gauge indicating the position of the resectoscope tip, while underneath are a set of control buttons and simple instructions for the surgeon. The controls are activated by touching a light pen to the screen over the appropriate button.

Imaging

winxp manager 7.0.9 keygen Once the robot is positioned at the bladder neck and the prostate measured, an ultrasound probe is passed down the resectoscope and the robot set to acquire scans and retract in 5mm intervals. This builds up a three dimensional ultrasound image of the prostate. Once this image is in the computer the surgeon can use it to design the cavity to be cut.

Cavity design

askysoft screen recorder crack Having scanned the prostate, the surgeon can mark on each image the region he wishes to remove. The cutting volume is then presented to him as a three dimensional model that he can manipulate to optimise the cutting volume and time. The image below shows the screen the surgeon uses to outline the cutting volume overlaid onto each slice of the ultrasound image. Drawing the outline is simply a matter of sketching it onto the ultrasound image with the light pen.

The computer starts by making each cone as long as possible, however the surgeon can fine-tune the cutting program by adjusting the cone lengths and turning on or off specific cones (the initial geometry specified by the surgeon may be such that some cones the computer generates more-or-less completely overlap other cones. A case in point is shown below. To save cutting time, the surgeon can shorten the right hand cone (marked green). Click here or on the image for a larger version.

Cutting

i sms crack s60v3 Finally, the robot is set to cut the prostate. Starting at the bladder neck and working backwards towards the verumontanum, each cone is cut as a sequence of concentric rings. When a cone is complete the robot retracts a little and cuts the next one. During the cutting procedure information is presented to the surgeon in three forms:

  • cst studio suite 2012 crack a side view in schematic form showing progress along the prostate
  • keygen horizon a video image from within the prostate

The real time image of the prostate is top-left, the schematic view showing a top-view of each cut is shown to the right, while each cut, overlaid on ultrasound is shown bottom right. A time indicator and position within the cutting program is also shown. In addition, since this is still at an early stage, engineering information is displayed at the bottom of the screen.
