This invention relates to MEMS X-ray sources based on carbon nanotube coated with metal oxides and metal oxide crystals and insulated with parylene for parallel microbeam intraoperative 100 to 1,000 Gy radiation therapies with minimal toxicity to normal tissue. It sterilizes cancer stem cells that cause tumor recurrence and metastasis. It generates high brightness, 10,000 to 20,000 Gy/s radiations that is closer to synchrotron radiation's dose rate. The parallel microbeam generating X-ray sources are microfabricated with CNT and its variant herringbone, stacked carbon nanotube. They are implantable or contact therapy X-ray sources. Each microfocus carbon nanotube based X-ray source is capable of switching a series of parallel microbeam simultaneously or in sequence. The 100-1,000 Gy single fraction radiosurgery exposes tumor antigens that induce local and systemic tumor immunity. It avoids adaptive resistance to radiation therapy as with 2 Gy daily fractionated radiation therapies that lasts several weeks.

Presented systems and methods facilitate efficient and effective generation and delivery of radiation. In one embodiment, a radiation generation component includes a high intensity target that produces Bremsstrahlung radiation in response to impacts by charged particles, wherein the high intensity target is configured with operating limitations based primarily on catastrophic failure mechanisms rather than fatigue failure mechanisms. The high intensity target is configured to be compatible with a loading system of a radiation generation system. The high intensity target can have a catastrophic failure strain percentage in the range of 0.5 to 4.0 percent. The catastrophic failure mechanisms can include at least one selected from the group comprising ultimate tensile strength, fracture strain, and melting point. The high intensity target can have a product life in a low cycle fatigue regime range. The high intensity target can comprise a material with a melting temperature in the range of 800 C. to 3,700 C. The high intensity target can be configured to load in an accelerator enclosure. The high intensity target can include an identification feature. The Bremsstrahlung radiation can correspond to average dose rates greater than 1.0 greys per second (Gy/s).

A method of obtaining, from a target compound, a radioisotope of a target element comprised in the target compound includes irradiating the target compound with high energy photon irradiation (gamma irradiation). Thereby the target element radioisotope is formed. The method is performed such that the target element radioisotope is of different oxidation state than the target element, and is comprised in a target element radioisotope compound that is separable from the target compound by a physical and/or chemical separation method.

Systems and methods for shuttle mode radiation delivery are described herein. One method for radiation delivery comprises moving the patient platform through the patient treatment region multiple times during a treatment session. This may be referred to as patient platform or couch shuttling (i.e., couch shuttle mode). Another method for radiation delivery comprises moving the therapeutic radiation source jaw across a range of positions during a treatment session. The jaw may move across the same range of positions multiple times during a treatment session. This may be referred to as jaw shuttling (i.e., jaw shuttle mode). Some methods combine couch shuttle mode and jaw shuttle mode. Methods of dynamic or pipelined normalization are also described.
