Biological optimization for tumor treatment plans can focus on local recurrence risk in tumor sub-volumes. Understanding the diagnostic accuracy of functional imaging is crucial for optimizing clinical outcomes.

Area of Science:

Radiation oncology
Medical imaging
Computational biology

Background:

Current treatment planning often optimizes based on individual tumor voxels.
Biological optimization offers a more nuanced approach by considering tumor sub-volumes.

Purpose of the Study:

To explore region-specific biological objective functions for treatment optimization.
To investigate the impact of diagnostic accuracy in functional imaging on treatment outcomes.

Main Methods:

Identifying and quantifying risk characteristics for local recurrence using functional imaging and biopsy data.
Analyzing the influence of sensitivity and specificity of imaging techniques on treatment planning.

Main Results:
