Commitments and Contingencies Disclosure [Text Block]	Note 9. Commitments As of March 31, 2024, the Company had commitments to purchase and install two Leksell Gamma Knife Esprit Systems (“Esprit”), one Gamma Plan workstation, one Linear Accelerator (“LINAC”) system, and one Magnetic Resonance imaging guided LINAC (“MR LINAC”). The LINAC, MR LINAC and one Esprit will be placed at future customer sites. The remaining Esprit upgrade is scheduled to occur during 2024 at an existing customer site. The Company also has one commitment to de-install a Gamma Knife unit at an existing customer site. Total Gamma Knife and LINAC commitments as of March 31, 2024 were $13,752,000. There are no deposits on the condensed consolidated balance sheets related to these commitments as of March 31, 2024. It is the Company’s 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 $13,042,000 and a line of credit of $7,000,000 and is actively engaged with financing resources to fund these projects. The Company borrowed $2,400,000 on the Revolving Line as of March 31, 2024, which was paid off in April 2024. On September 4, 2022, the Company entered into a Maintenance and Support Agreement, which provides for maintenance and support of the Company’s PBRT unit at Orlando Health from September 2022 through April 2026. The agreement requires an annual prepayment of $1,865,000 for the current contractual period ( one year). This payment portion was recorded as a prepaid contract and is being amortized over the one-year service period. As of March 31, 2024, the Company had commitments to service and maintain its Gamma Knife and PBRT equipment. The service commitments are carried out via contracts with Mevion, Elekta and Mobius Imaging, LLC. The Company’s commitments to purchase two LINAC systems also include a 9-year and 5-year agreement to service the equipment, respectively. Total service commitments as of March 31, 2024 were $14,120,000. The Gamma Knife and certain other 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.
