From treatment precision to hospital value: four business impacts
Markerless tumor tracking (PerfectTracking) is backed by data measured in clinical trials and clinical operation at QST Hospital. Here is how that precision translates into hospital management, in four points.
01
High precision = better treatment outcomes
Position error below 1 mm for 97.3% of the beam-on time. Margins can be kept to 2–3 mm, lowering the dose to normal tissue: fewer side effects, earlier discharge, higher turnover.
02
High precision = hypofractionation and shorter takt time
Because the tumor itself is tracked, hypofractionation becomes feasible. More patients can be treated per room per year, and the burden of hospital visits on patients is reduced.
03
Markerless = zero invasiveness, zero waiting
Patients who cannot receive markers become eligible. Lead time from referral to the start of treatment is shortened, preventing patients from leaving for other facilities.
04
Same result whoever operates = lower hiring hurdle
Operation does not depend on experience or skill level, reducing the burden of recruiting and training staff. Even small facilities can run respiratory-gated treatment.
