The present invention provides tissue processing systems, apparatus, and methods. [Solution] Provided herein is a system for treating patient tissue. The system comprises an energy delivery console and at least one energy delivery device. The energy delivery console can deliver a first dose of energy and a second dose of energy. The energy delivery device comprises a first delivery element configured to deliver a first dose of energy to target tissue and a second delivery element configured to deliver a second dose of energy to target tissue. The first dose of energy may include the delivery of energy that reversibly alters the target tissue, and the second dose of energy may include the delivery of energy that irreversibly alters the target tissue. The first dose of energy is delivered to enhance the therapy provided by the second dose of energy.

The invention relates to the technical field of traditional Chinese medicine pharmacy, and discloses a dynamic energy-adjusting traditional Chinese medicine electron beam gradient irradiation sterilization method which comprises the following steps: S1, online sensing and information fusion; s2, modeling a dose demand field; s3, energy dose mapping and energy adjustment strategy generation; s4, dynamic gradient irradiation is executed; and S5, process verification and feedback optimization. By sensing the thickness and density of the medicinal materials and non-uniform distribution of microbial loads on line and establishing a dynamic dose demand field matched with the thickness and density of the medicinal materials, 'on-demand distribution 'of doses is realized, so that a dose'demand window' is formed, and in the irradiation process, the system can automatically identify high-risk areas such as thick areas and microbial hotspots of the medicinal materials, so that the irradiation efficiency of the medicinal materials is improved. The energy deposition of the region is automatically improved; and the active ingredients and appearance quality of the medicinal materials are protected to the greatest extent while the sterilization effect is ensured.

The application discloses an X-ray thermoacoustic imaging method based on a diffusion model and sound velocity compensation and relates to the technical fields of X-ray thermoacoustic imaging and deep learning imaging reconstruction. The application fully considers the influence of the non-uniformity of sound velocity on the thermoacoustic wave propagation path and time delay, and proposes a new method of combining sound velocity compensation and diffusion model reconstruction; under the premise of not increasing the hardware complexity of the imaging system, the sound velocity modeling is used to realize the accurate correction of the wave propagation path, and the imaging artifacts and spatial positioning errors are effectively avoided; meanwhile, the image inversion framework based on the conditional diffusion model has excellent noise suppression and high-frequency detail recovery capability, and can generate high-quality thermoacoustic images with clear structure and significant contrast under imaging conditions such as low signal-to-noise ratio and low energy dose.

Systems (100) and methods for additive manufacturing are provided. In some embodiments, a method for additive manufacturing includes forming a portion of an additive manufacturing object within a reservoir (104) of a solidifiable material (102) by causing a plurality of energy beams (110) of a plurality of energy sources (108) to scan through a plurality of respective scan regions in the solidifiable material. The scan regions can overlap at one or more object locations such that a combined energy dose delivered to the one or more object locations by two or more of the energy beams is greater than or equal to a threshold dose for causing the solidifiable material to solidify. The method can also include advancing the reservoir of the solidifiable material relative to the energy sources. The forming process and the advancing process can be repeated to manufacture the additive manufacturing object.

A method of forming a microelectronic device includes forming positive tone photoresist on the microelectronic device, filling a trench, extending over a top surface adjacent to the trench, and covering a thickness monitor on a substrate containing the microelectronic device. The photoresist in and over the trench is exposed at a trench energy dose, and the photoresist in the monitor area is exposed at a monitor energy dose that is less than the trench energy dose. The photoresist is developed, leaving photoresist in the trench having an in-trench thickness less than the depth of the trench and leaving an in-monitor thickness of the photoresist on the monitor area less than an unexposed thickness. The in-monitor thickness of the photoresist on the monitor area may be measured and the measured thickness value may be used with a calibration chart to estimate the in-trench thickness of the photoresist.

This invention provides a method for measuring radiation dose that can be easily measured using readily available materials. [Solution] Using cellulose fibers or a structure made of cellulose fibers, radiation is irradiated onto the dosimeter material, thermogravimetric measurements are performed on the dosimeter material after radiation irradiation, the thermogravimetric rate of the dosimeter material is determined from the results of the thermogravimetric measurements, and the radiation dose corresponding to the thermogravimetric rate at any temperature within the range of 200°C to 300°C is obtained based on the correlation between the thermogravimetric rate and the radiation dose. As shown by arrows A and B in Figure 2, the electron beam irradiation energy (Dose) is estimated from the differential thermogravimetric first derivative rate (DTG).

A method of treating an eye condition associated with protein aggregation in the lens is disclosed. The method may include: radiating the eye with a radiofrequency (RF) energy dose in at least one frequency. The at least one frequency may be selected to cause disaggregation of lens protein aggregates of groups: a-crystallins, P-crystallins, and y- crystallins
