PseudoPatient®

PseudoPatient® is a unique, personalized approach that optimizes patient safety and treatment outcomes by minimizing the risk of side-effects during brain radiotherapy.

Our innovation allows for an integrated evaluation of all treatment processes via a patient-specific, anatomically-exact model of real patient’s head and brain tissue. By applying all processes on the exact anatomical replica, radiotherapy professionals are enabled to evaluate the whole treatment chain avoiding patient’s exposure to potential risks.

The critical demands in cranial radiotherapy applications (SRS/SRT) for accuracy and precision are met for the first time by PseudoPatient®: a truly personalized and individualized pre-treatment verification service.

PseudoPatient® advanced technology is internationally patented, FDA 510(k) cleared and ISO13485 certified.

The PseudoPatient® can accommodate any type(s) of detector or detectors the end-user would like, placed at any designated locations within the brain. This allows dosimetry tailored to the user’s needs and dosimeters availability. Placing detectors at designated locations also allows for dose measurements at the most dosimetrically demanding areas and clinical cases. In contrast, other commercially available solutions can accommodate inserts for dosimeters at limited pre-defined positions using selected dosimeters without any room for customizability/flexibility.

Key Features

  • Exact anatomical replica of real patient’s anatomy.
  • Direct measurements on anatomic regions of high interest (PTV, OAR). Providing options as High spatial resolution (of ~1mm³) 3D relative dosimetry. Absolute 2D film dosimetry. Absolute point dose measurements.
  • End-to-end evaluation of all treatment processes.
  • Medical record evidence of true treatment results under realistic conditions.

Intended for

Patient-specific pre-treatment verification of all radiotherapy processes.

Unique value-adds of PseudoPatient® are for:

  • Patients: Treatment checked, approved, improved or rejected prior to real implementation. Potentially leading to better outcomes, lower side-effects, and higher quality of life.
  • Clinicians: : Increased confidence in complex brain treatment delivery and total control of the process, Consultation tool for better doctor-patient communication.
  • Physicists: Minimization of uncertainties. Individualized quality monitoring through real end-to-end pre-treatment testing.
  • Clinics: Faster adoption of latest techniques, (such as SRS), leading to higher patient throughput and ROI, as well as data acquisition on individual treatment accuracy. Opportunity for data-driven continuous improvement and standardization. Differentiation and stronger brand name through unique patient experience, aiming to address the specific individualized needs for maximized safety and efficacy.

PseudoPatient vs other approaches

  • The PseudoPatient ® phantom is an exact anatomic replica of the real patient. It is NOT an approximation, human-looking android.
  • Availability of the real patient’s CT scan allows for more realistic contouring of organs-at-risk and target locations involved in intracranial SRS (e.g., brainstem, optic chiasm, etc.).
  • Dose measurements can be implemented in prescribed regions of interest specifically for each case, achieving true end-to-end verification.
  • The PseudoPatient® phantom can be filled with polymer gel covering the total brain-tissue volume, enabling high-fidelity 3D dose measurements (resolution of approximately 1mm3).
