Commitments and Contingencies Disclosure [Text Block]	Note 8. Commitments As of September 30, 2025, the Company had commitments to purchase and install two Leksell Gamma Knife Esprit Systems (“Esprit”) and two Linear Accelerator (“LINAC”) systems. The Esprit upgrades and one LINAC installation are anticipated to occur in the first or second quarter of 2026 or later at existing customer sites. The remaining LINAC is reserved for a future customer site. Total Gamma Knife and LINAC commitments as of September 30, 2025 were $7,884,000. There are no deposits on the condensed consolidated balance sheets related to these commitments as of September 30, 2025, nor are there any penalties if the Company decides to not execute on these commitments. It is the Company’s current intent to finance substantially all of these commitments. There can be no assurance that financing will be available for the Company’s current or future projects, or at terms that are acceptable to the Company. However, the Company currently has cash on hand of $5,345,000 and capacity under its Revolving Line of $7,000,000. The Company borrowed $2,000,000 on the Revolving Line as of September 30, 2025, which was repaid in October 2025. On September 4, 2022, the Company entered into a Maintenance and Support Agreement with Mevion Medical Systems, Inc. (“Mevion”), which provides for maintenance and support of the Company’s PBRT unit at Orlando Health from September 2022 through April 2026. The Company’s maintenance commitment for the final service period, September 2025 through April 2026, is $1,184,000. As of September 30, 2025, the Company had commitments to service and maintain its Gamma Knife, LINAC, and PBRT equipment. The service commitments are carried out via contracts with Mevion, Elekta, Solutech, and Mobius Imaging, LLC. The Company’s commitment to purchase one LINAC system also includes a 5-year agreement to service the equipment, respectively. Total service commitments as of September 30, 2025 were $6,870,000. The service contracts are paid monthly, as service is performed. The Company believes that cash flow from cash on hand and operations will be sufficient to cover these payments.
