Radiation therapy dose calculation methods, systems and computer program products, for use with a treatment delivery device for treating a patient and utilizing a scattered radiation detector in making independent dose calculations. The scattered radiation detector is configured to acquire measurement information during patient treatment, which is used to determine an estimate of the output of the treatment delivery device. Other information is acquired including patient imaging data, gantry angle information and collimator position information utilized during patient treatment. The acquired information is utilized along with the treatment delivery device output estimate to determine dose delivered to the patient.

Radiation therapy dose calculation

A radiotherapy system includes a radiotherapy device, such as a LINAC, operable to direct a radiation beam from a head thereof during operation, a field detector positioned to be within the radiation beam during operation of the radiotherapy device and operable to generate a beam measurement signal, a reference detector positioned to be outside of the radiation beam during operation of the radiotherapy device and operable to generate a reference signal, and at least one computer in signal communication with the field detector and the reference detector and configured with software to normalize the beam measurement signal based on the reference signal and to output a normalized beam measurement.

System and method for radiation beam measurement normalization

A lift table provides stability and portability for a radiation measurement scanning system. The lift table may be fixed for radiation measurement or configured for storage. Further, the lift table may be easily disassembled and assembled to allow efficient transporting. The lift table supports a multiple axes scanning system for measuring radiation from a radiation source, such as a linear accelerator (LINAC) and includes a leveling platform, all of which are provided by a desirable weight and portability.
