HIT 3 // Virtual simulation – 3 mobile lasers

ImageProduct HIT 3

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 in radiotherapy.
The HIT 3 is compatible with all CT scanners.

The HIT 3 laser positioning system consists of
- three mobile lasers: that generate one sagittal vertical line and two lateral horizontal lines,
- and two fixed lasers: that generate a vertical line on each side of the patient.



Your solution to adapt the height of transversal lasers!
The key advantage of the HIT3 configuration is that all the lines are in independent boxes. This means that adjustable positioning/fixation of transversal lasers enables deeper laser-line projection (for example, for larger patients).

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 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.
