HIT 5 // Virtual simulation – 5 mobile lasers

Adapted to each radiation treatment room, HIT (High Impact Technology) laser positioning systems distinguish themselves by allowing to treat patients with greater accuracy (up to +/- 0.1mm). Plus, it makes the adjustment of the equipment automatically and faster. The HIT system optimizes the time spent treating patients and improves the usability for the professionals operating the equipment.

CYRPA’s HIT precise patient positioning lasers allow a faster and more accurate virtual simulation.
Le HIT 5 is compatible with all CT scanners.

The HIT 5 system is composed of five mobile lasers that generate:

- A sagittal vertical line
- Two vertical transversal lines
- Two horizontal lines


Thanks to the fact that all five lasers are mobile no couch movement is needed on the transversal plane.

With a touch of a button the cross or the diode laser line may be red and/or green, with every time a precision of positioning of +/-0,1mm, offering a more precise and faster use. The double diode can be adapted to each patient’s skin tone and has the advantage of a built-in redundancy. The change from one color to the other is done remotely and instantly.

The adjustments of the laser beams are accessible remotely via a Tablet PC and a wireless network and with a PC in the control room with CYRPASoft.This session of adjustments lasts approximately 10 minutes.

The system is coupled to a phantom for the automatic adjustment and calibration of the laser beams, which is called the “SmartPhantom CT”.

And what about double-checked accuracy?
The CYRPA technology for mobile lasers includes a built-in microprocessor and encoder that gives real-time feedback to the software on the requested position. Additional to this, an external linear encoder verifies the position of the optical head, and double-checks its position to ensure the best accuracy in patient-positioning.
