Title: Innovations by Keith A. Solberg
Introduction
Keith A. Solberg is an accomplished inventor based in Bloomington, IN (US). He holds 2 patents that contribute significantly to the field of ion beam therapy. His work focuses on developing advanced dosimetry systems that enhance the precision and effectiveness of cancer treatments.
Latest Patents
One of his latest patents is titled "Fast, high-rate, position-sensitive absolute dosimeter for ion beam therapy." This invention features a gas scintillation detector designed to provide in-beam absolute dose monitoring for ion beam radiotherapy treatments. It employs spot or raster beam scanning, particularly with microsecond-scale beam pulses. The detector captures prompt primary scintillation light emitted by gas molecules excited by the beam, yielding electronic signals that can be processed to provide output data proportional to the delivered dose. This capability allows for real-time feedback to adjust beam intensity during treatment. Additionally, when multiple photo-detectors collect scintillation light, the invention can measure spot beam position with spatial resolutions of approximately one millimeter.
Another significant patent is the "Dose profile measurement system for clinical proton fields." This invention includes a beam profile measurement detector that efficiently verifies dose distributions created with active methods of clinical proton beam delivery. The Multi-Pad Ionization Chamber (MPIC) consists of 128 ionization chambers arranged in one plane, measuring lateral profiles in fields up to 38 cm in diameter. The MPIC pads have a 5 mm pitch for fields up to 20 cm in diameter and a 7 mm pitch for larger fields, achieving an accuracy of about 0.5 mm in field size determination. The Multi-Layer Ionization Chamber (MLIC) detector contains 122 small-volume ionization chambers stacked for depth-dose profile measurements, capable of measuring profiles up to 20 cm in depth with high precision.
