SPECT/PET Image Reconstruction Scientist — Hybrid

Inovait; Vancouver; Hybrid; CAD 100,000 - 130,000; Full time

Job summary

Ascinta, based in Vancouver, BC, is hiring an Applied Physicist to develop SPECT and PET image reconstruction algorithms. You will benchmark iterative reconstruction, perform Monte Carlo simulations, and validate methods using simulated and clinical datasets alongside medical physicists and software engineers.

Join a team focused on cancer therapy via advanced imaging with production-quality code in C/C++, optimization for CPU/GPU, and collaboration across academia and industry.

Qualifications

• M.Sc. or Ph.D. in Physics or related field.
• Strong background in particle physics and radiation detection.
• Experience formulating and solving inverse problems; knowledge of EM.
• Strong numerical methods and linear algebra.
• Hands-on Monte Carlo simulations (Geant4, GATE, MCNP, FLUKA).
• Strong Python and C/C++ programming.

Responsibilities

• Design, implement, and validate iterative tomographic reconstruction for SPECT and PET imaging.
• Develop and validate Monte Carlo particle transport simulations of imaging systems with system modelling.
• Generate simulated validation PET/SPECT datasets; define quantitative performance metrics and verify accuracy.
• Formulate and solve inverse problems, including accurate system matrix modeling and corrections for physical degradation effects.
• Write high-performance reconstruction code in C/C++ and optimize speed and resources on CPU/GPU hardware.
• Benchmark reconstruction performance with systematic parameter optimization using realistic patient simulations and phantom scans.
• Collaborate with software engineers to integrate reconstruction workflows into Ascinta's software ecosystem.
• Participate in scientific research activities; contribute to reports, conferences, and publications.
