SIORT Flash system

1.1 Beam specifications: Energy and radiation fields The ElectronFlash linear accelerator works in electron mode only. The standard device is provided with two different nominal electron energies: 7 MeV and 9 MeV. ElectronFlash can provide different radiation fields, ranging from Ø 1 cm up to Ø 12 cm. The flatness of lateral profiles, measured at zref depth, is equal or better than 7% at the nominal distance 100 cm between the sample and the electron exit window. The symmetry of the radiation field is better than 3%. Fields are available both in circular and in squircle shape with side (diameter) 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 12 cm. Additional fields can be provided on request.

1.2 Available Dose Rates The ElectronFlash can vary its dose rate from 0.005 Gy/s up to 1200 Gy/s with reference field Ø 10 cm. Dose rate is varied by modifying all the parameters hereinafter listed, being these settings one each other independent: − E-gun Peak current; − E-gun pulse duration: it can be set in the range from 0.2 μs up 4 μs; − Pulse Repetition Frequency (PRF): it can be set in the range from 1 Hz up 350 Hz with 1 Hz increment. The ElectronFlash Control Interface allows to program an irradiation in three modalities: 1. Single pulse irradiation; 2. Train of pulses; 3. Irradiation halted by Monitor Units reading. If ElectronFlash irradiates in modality 2 (Train of pulses), intervals between pulse trains (i.e., m pulses followed by n pulses) from 5 ms to 1 min are programmable by the End User.

1.3 Control system Machine and beam diagnosis is designed according to IEC 60601-2-1, the standard describing the requirement for a Medical Radiotherapy linac (Medical electrical equipment - Part 2-1: Particular requirements for the basic safety and essential performance of electron accelerators in the range 1 MeV to 50 MeV). Safety and security interlocks are provided and displayed, in particular all the interlocks that guarantee the safety of the operators (doors, emergency buttons). Before executing any irradiation, the beam energy and the desired dose rate must be programmed and consequently displayed at Control System. The Human Machine Interface (HMI) allows to display and edit the parameters hereinafter listed:
− E-gun Peak current;
− E-gun pulse duration: it can be set in the range from 0.2 μs up 4 μs;
− Pulse Repetition Frequency (PRF): it can be set in the range from 1 Hz up 350 Hz with 1 Hz increment.
− Monitor Unit – both MU set and delivered, as per EN 60601-2-1;
− Number of pulses: Number of pulses set and delivered.

CT scan installed

As a result of several years of work, they were able to install a new CT machine at the J. Endre Szántó United Social and Health Institute. The official handover ceremony of the device was held in the afternoon of December 14 at the clinic. As the opening of the event, Elek Boglárka Répásiné and her student Ivett Bodnár performed a short song and violin program. At the event, the director Dr. Géza Bobkó greeted the gathering and introduced the institution. The dispensary was founded in 1984, at which time care continued in several separate buildings scattered throughout the city.

The currently operating unit was built in 1990, which has been responsible for the day-to-day care of patients since then. There are currently 30 specialist clinics operating, where they primarily treat patients from the Szerencsi district, but there are overlaps with other areas as well. This year, a total of 128,000 patients visited the clinic until November 30, i.e. approximately 400 people per day. In 2017, they dreamed that they would also like to perform CT examinations locally, for which they submitted their application even then. Due to a lack of funds, they did not receive the grant then, but in 2021 they managed to win the amount of more than HUF 200 million. Dr. contributed to the implementation of the application. Deputy Minister Zsófia Koncz, also a Member of Parliament, said in her speech that her father already believed in this project. He considers this development unique, as it is rarely possible to perform CT examinations in rural towns, and Szerencs is the first such town in the county. This is a great opportunity, as the time factor is important in health care, and less waiting time can often save lives. He emphasized that, as a result of a lot of work, this is a special gift to Szerencs and the region before Christmas.

The instrument was presented by radiologist Dr. Szilvia Varga. During his lecture, he first described the history of medical imaging devices, which have undergone significant changes in their methods and the time required for the examination over the decades. The device arriving at Szerencs is a SinoVision AlphaCT 358 Plus model, which has a larger 75 cm diameter opening than the traditional CT opening. With the tender, they also received a new ultrasound machine, a Mindray DC-70 type. Tibor Nyiri, the mayor of the city, took the floor, who considers the development of technology and healthcare to be of such a high standard. He emphasized that the fight against pathogens is continuous, viruses and diseases are part of everyday life. It is important that people receive the best care here in Szerencs as well. The head of the city emphasized that the preparation and implementation of a tender is a complex process that requires serious teamwork and collaboration. In his opinion, it is a reassuring feeling that the waiting and response times are getting shorter, as well as knowing that you can count on the workers here. After the mayor's speech, a toast was held to celebrate this momentous occasion. After the champagne toasts, the ribbon in the national color was cut, which officially put the new CT device into use. At the end of the event, the attendees had the opportunity to view the device and the spaces created for it. The tender for the development of the outpatient specialist care center in the Szerencs region was thus concluded, and the city's dispensary was further enriched as a result.
